Movement Of Small Intestine Biology Essay

Movement Of Small Intestine Biology Essay In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food called a bolus while in the esophagus and gastrointestinal tract and chyme in the stomach along the gastrointestinal tract. Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward. Catastalsis is a related intestinal muscle process.(Google) Movement of small intestine The small intestine is responsible for removing nutrients from food and bringing water and electrolytes in the body. It also moves food through a specific part of the digestive tract, into the large intestine Once processed and digested by the stomach, the milky chyme is squeezed through the pyloric sphincter into the small intestine. Once past the stomach a typical peristaltic wave will only last for a few seconds, travelling at only a few centimeters per second. Its primary purpose is to mix the chyme in the intestine rather than to move it forward in the intestine. Through this process of mixing and continued digestion and absorption of nutrients, the chyme gradually works its way through the small intestine to the large intestine. During vomiting the propulsion of food up the esophagus and out the mouth comes from contraction of the abdominal muscles; peristalsis does not reverse in the esophagus. Types of contraction.(Guyton pg# 786) There are two main types of contractions that occur in the small intestine as well as other parts of the gastrointestinal tract. These movements are known as mixing contractions or segmentation contractions and propulsive contractions. While these contractions are categorized separately, both perform similar functions. Mixing movements mainly churns food but also propels it. Propulsive movements primarily push food towards the anus but also spreads it out for allowing the digestive enzymes to mix with it. Mixing or Segmentations contraction When a portion of small intestine becomes distended with chyme,stretching of the intestinal wall elicits localized cocentric contractions spaced at intervals along the intestine and lasting a fraction of minute.The contraction cause segmentation of the small intestine.They divide the intestine in to spaced segments that have the appearance of a chain.As one set of contraction relaxes a new set often begins,but the contraction this time occur mainly at new points between the previous contractions.Therefore the segmentation contraction chop the chyme two to three times per minute. The segmentation contractions become exceedingly weak when the excitatory activity of the enteric nervous system is blocked by the drug atropine. (Guyton pg # 786) While mixing contractions also propels food through the small intestine, its main function is to churn the chyme with intestinal enzymes and mechanically break down some particles.(Google) Propulsive Movements or contraction Chyme is propelled through the small intestine by peristaltic waves.These can occur in any part of small intestine ,and they move towards the anus at a velocity of 0.5 to 2.0 cm/sec,faster in the proximal intestine and slower in the terminal intestine.They normally are very weak and die out after traveling only 3 to 5 cm.This means that 3 to 5 hours are required for passage of chyme from the pylorus to the ileolic valve.(Guyton pg #787) These contractions are concentric meaning that they run around the intestine as illustrated in the diagram below. These spaced segments relax and constrict a number of times thereby à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"choppingà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚  the chyme and mixing it back and forth with enzymes, mucus, water and ions in the intestine. These contractions occur about 10 to 12 times per minute in the duodenum (first part) and jejunum (mid) of the small intestine and diminish to about 8 or 9 contractions per minute in the terminal ileum (end portion).(Google) Control of Movement through the Small Intestine A number of hormonal and nervous factors initiate and maintain peristalsis and mixing. Nerve impulses which travel throughout the small intestine are triggered by the gastroenteric reflex (refer to Defecation Reflex) and localized distention of the duodenum. These impulses are propagated via the enteric nervous system, mainly the myenteric plexus, which is the gutà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s own internal network of nerves. It is further regulated by impulses from the central nervous system via the vagus nerve and sympathetic trunk.. The   digestive hormones, cholecystokinin (CCK), gastrin and motilin increase intestinal motility while secretin decreases the activity. In addition, serotonin and insulin can increase motility while glucagon can decrease motility.(Google) Ileocecal Valve The ileocecal valve controls the entry of chyme into the colon and prevents backflow of fecal matter into the ileum of the small intestine.A principal function of the ileolic valve is to prevent backflow of fecal contents from the colon in to the small intestine. It has valve lips that closes when the pressure in the cecum builds up. In addition, the end portion of the ileum, just proximal to the ileocecal valve, has a muscular sphincter called the ileolic sphincter. This is constantly constricted and restricts the flow of chyme from ileum into the cecum unless appropriately stimulated to relax and thereby open. The ileocecal sphincter ensures that intestinal contents stay within the small intestine long enough for sufficient absorption of nutrients.(Guyton pg # 788) Motility disorders in small intestine Problems in the small intestine occur when food is blocked, unable to move, or contains bacteria that cannot be broken down by small intestine cells. Intestinal Dysmotility is a dysfunction that hampers peristalsis, or the contractions that move food forward. When food cannot move forward, cramps and headaches occur in the patient because the digestive process has been stopped unnaturally. Bacterial Overgrowth is a condition that leads to immediate expulsion in the small intestine. If there is an overload of bacteria, the small intestine cannot handle it, and stomach pains and vomiting occur. Cancer can strike the small intestine, although it usually is detected in other parts of the body first. Worms and parasites can occasionally affect small intestine health, although these can most often be removed by careful surgeons or specialized medicines.(Google) Movement in large intestine Movement of food through the large intestine is caused by smooth muscle contraction called peristalsis the best way to describe this is to imagine how a snake moves its abdominal muscles to move. As opposed to the more continuous peristalsis of the small intestines, faecal contents are propelled into the large intestine by periodic mass movements. These mass movements occur one to three times per day in the large intestines and colon, and help propel the contents from the large intestine through the colon to the rectum.(Google) Principal functions of colon are It absorbs water from indigestible food matter and then passes useless waste material from the body. It absorbs all the calcium. Water is added to undigested food to digest it easily.It absorbs water from indigestible food matter and then passes useless waste material from the body. Actually no digestion takes place in the large intestine this organ is almost entirely for water absorption. In the colon, the major process that takes place is the reabsorption of water.(Guyton pg # 788) Types of movements or contractions The movements still have characteristics similar to those of small intestine can be divided into mixing movements or Haustrations and propulsive movements or Mass movements. Mixing movement In the same manner the segmentation movements occur in the small intestine large circular contractions occur in the large intestine,about 2.5 cm of circular muscle contracts.At the same time longitudinal muscles contracts.These combined contractions cause the unstimulated portion of the large intestine to bulge outward in to bag like sacs called haustrations. Mass movements Much of the propulsions in the cecum and ascending colon results from the slow but persistent haustral contractions requiring as many as 8 to 15 hours to move the chyme from the ileolic valve through the colon while the chyme itself becomes fecal in quality a semisolid slush instead of semifluid.A seriesof mass movements usually persists for 10 to 30 minutes .then they cease but reurn perhaps a half day later.When they have forced mass of feces into the rectum the desire for defecation is felt.(Guyton pg #789) Another very important type of motility that occurs in the large intestine is the high amplitude propagating contraction (HAPC). These contractions only occur 6-8 times per day in healthy people, but they are extremely strong contractions, which begin in the first part of the large intestine and sweep around all the way to the rectum; they stop just above the rectum.(Google) Motility Disorders of the Large Intestine Constipation Constipation is usually described as infrequent bowel movements (less than 3 per week), passage of hard stools, and sometimes difficulty in passing stools. The sensations associated with constipation can include a constant feeling of needing to go, or a sensation of bloating or fullness. In children, constipation often leads to fecal incontinence. Diarrhea The symptoms of diarrhea are frequent, loose or watery stools, and a subjective sense of urgency. Patients with diarrhea also may worry about loss of control over bowel movements. An excessive number of high amplitude propagating contractions can be a cause of diarrhea Hirschsprungs disease Hirschspurngs disease is a rare congenital (a person is born with it) disorder that is caused by absence of nerve cells (ganglion) in the rectum and/or colon. Usually the problem involves only the bottom portion of the colon, but in some it involves the entire colon or even part of the small intestine. The part of the bowel that lacks nerve cells (aganglionic) cannot propel stool toward the anus, and therefore results in obstruction, severe constipation, or inflammation (enterocolitis). Although symptoms usually begin within a few days after birth, some people dont develop them until childhood or even adulthood. Irritable bowel syndrome (IBS) The term irritable bowel syndrome, or IBS, is used to describe a group of symptoms that occur together. These symptoms include abdominal discomfort or pain and altered bowel habit, either constipation or diarrhea. Some people have both constipation and diarrhea, just at different times. Bloating or distention of the abdomen is also common. IBS symptoms are believed to be caused partly by abnormal motility.(Google)

Cyclical Political Theory Essay

Personally, I subscribe to the opinion that what we have in this world is a necessary connection between things. Technically, something can not come out of nothing. Actions are interrelated and whether we accept it or not, they overlap. Thus, I accept George Modelski’s position in his cyclical political theory. However for me, this principle is not only limited to only political events but all areas of life. In the case of World War I and World War II, I hold the position that both of them are not two separate political events. Why do I hold this claim? The truth is that if we look at both events critically, one would see that both wars are one and the same, only that it was fought in different locations and at different years. I provide the reasons for my position below. To begin with, the issues that surrounded the war are one and the same. The Germans wanted to dominate Europe and knew that to achieve this, they had to root out some other powerful nations like France, Britain, Russia and America. The German leaders also felt threatened by the expansion of Russia and wanted to root them out before they could overshadow the Germans. Furthermore, both of them were between colonial Lords. Apart from this, both wars was a scenario where the good guys are trying to stop the bad guys – the Allies being the good guys while Germany and their alliance being the bad guys. In both wars, we see elements of ideological propagation where one party wanted to feed their ideas to the other party. Summarily, I believe that the world war two was just a way of bringing what could have been brought to an end in World War I to an end. It involved the same set of people who were fight for the same cause and wanted to achieve the same results.

Introduction to Immanuel Kant’s Theory of Deontology

Christian J McGinley, Essay #3, pg. 282-319, Question #12 on pg. 303 In chapter six of the textbook titled The Moral of the Story we are introduced to Immanuel Kant’s theory of deontology. This theory is one that deals with moral obligations and refers to the decisions that rational beings make when deciding if an action can be accepted through the process of the categorical imperative or not. There are many factors that contribute to this belief however there is also a long list of flaws that play a crucial role in determining whether this theory is one that we can be held accountable or not. In this essay I will evaluate and analyze the statements provided to me at the end of the chapter that deal specifically with Immanuel Kant’s test on the categorical imperative as well as the concept of â€Å"a means to an end†. In the first set of questions listed at the end of chapter six I was encountered with a statement from Emmanuel Kant that revolved around the topic of â€Å"good will†. Kant read, â€Å"Actions are morally good only if they are done because of a good will† What Kant is saying is that consequences don’t make an action morally good, but on the other hand, good will does. Kant describes good will as a respect for the moral law expressed through ones intentions (Rosenstand, 283). The person must imagine his intentions to be a good thing for all people to practice in general, not because it will make people happy, but rather for the reason being that it is the basic principalShow MoreRelatedEssay about Business Ethics and Kant1466 Words   |  6 PagesIntroduction The purpose of this paper is to discuss how Adelphia Communications’ leadership, particularly the Rigas family, violated the trust of the public and its investors through unethical and illegal business practices.

Theodore Roosevelt s Study Of The War Of 1812 - 1318 Words

Background Theodore Roosevelt was born on October 27, 1858 and died on January 6, 1919. He was the son of Theodore Roosevelt Senior, and Martha Stewart Bulloch, and was fortunate enough to attend Harvard University and Colombia Law School. He accomplished a lot of things in his life which led to him having a successful career in whatever he pursued. He was a politician, author naturalist, soldier, explorer, and historian who happened to become the 26th president of the United States of America. Roosevelt as a Naval Officer Roosevelt started off by writing a book while still at Harvard about the Naval War of 1812 and how the US Navy played a huge role. In this book he illustrated different strategies that could’ve been used†¦show more content†¦With John D. Long sick, the current secretary of navy, Roosevelt was able to test some of his theories out while he prepared for war with Spain, which led to a naval dominance by the Americas. New York City’s Police Commissioner It all began by Roosevelt declining to run for Mayor of New York in 1894. By 1895 Roosevelt became president of the board of New York City Police Commissioners for two years and started to change the police force. As he took the president spot, the New York Police Department was known for being the most corrupt in America at the time. Roosevelt would have regular inspections of the police department and would pick new rookies based on their physical and mental statues. Roosevelt being the smart man that he was, would make a habit of walking through officers territories at night and in the morning to make sure they were doing their jobs and weren’t slacking. With the breaking apart of the board of commissioners, time would tell that Roosevelt would later replace the whole Police Commissioners with a single Police Commissioner. Theodore Roosevelt as Vice-President Roosevelt originally wanted a second term as governor or to be in the cabinet of the War Department, his closest friend Henry Cabot Lodge saw that this was a dead end and encouraged him to try and become a vice president. McKinley refused to make Roosevelt the secretary of war but didn’t have a problem to allow him to become a Vice President. Roosevelt as Vice President was

MAJOR CHARACTERS: Marlene, Effita, No Name, Nathan, Miss Minnie, Raymond, Ionie, Maas Barber, Long Man, Cudjoe Man, Dolly, Minna, Mr. Papacita. RECOLLECTIONS/ STORIES 1. ‘EFFITA’ This is a recollection of the Sunday ritual of taking food to Aunt Sare. Her habit of praying for the carrier of the food is explored in great detail. The comedic telling of Effie’s death announcements is another detail that is explored. We learn what happens when she gives a wrong announcement for Melwyn, and no announcement for Son Son. This recollection ends with Effie’s death in 1995, with the implication that few people attended her funeral, despite the fact that most of the people in the district were related. SETTING: Green Town, Maaga Bay, Lucea, Montego Bay. CHARACTERS: Marlene/ Nice – the protagonist and narrator. Effita – the person who did informal death announcements for the district. Son Son – the narrator’s male schoolmate who died, also Effie’s nephew. Melwyn – Marlene’s cousin who was shot by Chisel Bwoy, then given an incorrect death announcement by Effie.

She put her reclusive nature on pause once a month, when she went to town in order to visit the post office to collect packages. The story gets interesting when she got pregnant and no-one knew the father. The child became her life, and she shared him with no one, but kept him to herself. He turned out to be even more silent than his mother. It was, however, rumoured that Maas Barber, Marlene’s father, was the child’s father. In between the telling of this story, is Marlene’s explanation of her own silence. SETTING: Tam Briscoe Hill, Baltree District, CHARACTERS Marlene/ Nice – the protagonist and narrator.

Nerissa Black – Wellesley’s sister and a pupil teacher who taught the lower grades. THEMES: childhood lessons, education and society, silence. 5. ‘MISS MINNIE’ This is the story of Raymond and Miss Minnie. Miss Minnie got married to Lester after his girlfriend deserted him, as well as their young son Raymond. Miss Minnie was an extremely good mother to Raymond, making him the centre of her life, especially after Lester died. Raymond became a successful individual and took Miss Minnie with him to live in Kingston. Great changes occurred in Kingston because he met his mother and brothers, which created waves in the relationship between himself and Miss Minnie. She was eventually diagnosed with depression and low self esteem. This created another change in their relationship, to the point where Raymond would not allow another woman to get between him and Miss Minnie. Marlene declares that, based on this fact, she cannot wait on him because he will never marry as long as Miss Minnie is alive. SETTING: Baltree District, Lucea, Kingston.

There is parental love, as represented by Cudjoe Man and Dolly. Cudjoe Man is admired throughout the district for his devotion to his mentally challenged daughter. He combs her hair, dresses her, provides for her every need and is extremely protective of her. He even disregards his attraction to Minna, a possible love match, in order to concentrate on his child. We also learn of a contrasting relationship between Minna and Samson. The romantic love between theses two people is polluted by physical abuse. This abuse is whispered throughout the district, but things come to a head when Samson beats Minna with such trength and aggression that she is hospitalized. This beating occurred because Minna got in a fight with Dottie over Cudjoe Man.

Information System And The Pyramid Model - Click to Get Solution

Question: Discuss about the Information System and the Pyramid Model. Answer: Introduction Pepper Mint Food (PMF) is a business that is owned by Catherine Siddhoti and is based out of Maree. Catherine had started the business at her home and was started locals and tourists. There are six staff personnel in PMF and have been allocated in kitchen and delivery departments. With the increase in staff members and the expansion of business, it is becoming difficult for Catherine to manage everything through manual processes. The other competitors are gradually gaining advantage through this drawback and the use of Information Systems has been suggested to Catherine for efficient management. Information Systems Information systems are a combination of hardware and software that is required for the management of data-sensitive and data-driven applications (Systems and Systems, 2016). It would help in the analysis and storage of the data. The prime purpose of Information Systems is to transform the raw data in to meaningful information (Study.com, 2016). A special form of such systems is a management information system (MIS), which provides information for managing an enterprise (WhatIs.com, 2016). These systems are divided in to two broad categories as: General purpose Information Systems Specialized Information Systems Benefits of using Information Systems Communicatio IS makes the communication between different parties easy and quick. Catherine can easily communicate with her staff members through instant messaging, emails and video calls. Globalization and cultural gap The linguistic, cultural and geographical boundaries can be reduced with the adaption of Information Systems. Sharing of information and communication becomes a lot easier. Availability Availability of the services at all times is desired by the customers. IS would enable PMF to make the information and the services available 24x7. Cost effectiveness and productivity Supply of information to the decision-makers is an effective process required in the business. Use of IS in PMF would ensure cost-savings and the productivity will also increase by a good percentage. Information Systems for PMF The basic requirements of PMF from IS are to manage the customer details, variety of meals and pricing information along with the salaries and management of the resources. Excellent delivery system and the management of raw materials is also desired by PMF. The different types of Information Systems that would benefit PMF are as listed below. Transaction Processing Systems These are the systems which are used to maintain and manage all the transaction involved with the organization. Payroll Systems Order processing systems Stock control systems Database management systems The above four systems are suggested for PMF which would help Catherine in managing the salaries of the workers, process the delivery orders places by the customers, manage the raw material and pricing information and also monitor the inventories and products in an out of stock along with their quantities (Chris-kimble.com, 2016). Management Information Systems (MIS) These are the systems that are used by the top and middle level management for smooth running of all the activities and operations. Budgeting Systems Inventory control systems These can be used by PMF for detailed reports and would help in budgeting of the entire business and activities involved under it. Decision Support Systems They offer access to databases, analytical tools, allow "what if" simulations, and may support the exchange of information within the organization. These are the knowledge based systems which are used for modeling and analytical purposes. It would be of good aid for PMF for supporting the management decisions as they have analytical and modeling capability. These would allow the management to make correct decisions such as those revolving around financial planning and logistics systems. Management Decision through IS Management decisions can be effectively taking with the help of suggested information systems for PMF. It would allow Catherine to Making a proper budget plan for the business Assess the demands and preferences of the users Predict the future demands through the analytics results Resource management and allocation of roles to the workers along with their wages and salaries Differentiate correctly between the internal and external data sources Decision on the expansion of business to other locations Extension of the delivery time to maintain the availability of the system at all times Porters Competitive Force Model Five Forces Model was designed by Porter to develop business strategies on the basis of five suggested factors (Resources et al., 2014). The model is as described below. The model can be used by PMF for winning over the competitors in the market that is currently taking over the clients of PMF. It would also help in deciding the supplies and understanding of the preferences of the customers (Competition, 2015). Use of Computer Networks in Communication and Collaboration Computer networks such as intranets and extranets along with the internet are mandatory for PMF to have good communication management and collaboration with the stakeholders in place. Digital communication networks and local area network (LANs) can be utilized by Catherine to communicate with the staff and customers (vub.ac.be, 2016). It would be useful for PMF to Sharing of the resources among the team and staff Efficient exchange of information with the staff and customers Information sharing by using Web or Internet Interaction with other users using dynamic web pages Video conferences Parallel computing Instant messaging (tutorialspoint, 2016) Management Challenges Some of the management challenges that would occur and need to be implemented during the installation of Information Systems are: There are multiple models for the Information Systems on the basis of several factors. The choice of which model to adapt to can be challenging for Catherine Lending methodologies also differ as there is no generalized concept under this Resistance of employees to bring the newer systems in practice can be challenging as well. Proper training and manuals would have to be provided to the resources Cost constraints would also play a significant role as installation of Information Systems would require a budget to bring it in service (sa-dhan.net, 2016) Social and Ethical Issues Ethics are the principles that help in differentiating between right and wrong. IS has invited some of the ethical questions for individuals as well as for the society as it would bring along a vast social change and has the potential to threaten the existing systems in terms of money, rights and policies. These systems have the power to achieve excellent social progress and at the same time can be used to commit crimes related to information and digital media. Ethical issues have emerged as an urgent issue in the world of Internet. IS makes it easier to assemble and integrate the information but the issues such as keeping the customer information safe along with the protection of policies and rights such as intellectual property and privacy emerge. Other pressing ethical issues raised by information systems include establishing accountability for the consequences of information systems, setting standards to safeguard system quality that protects the safety of the individual and society, and preserving values and institutions considered essential to the quality of life in an information society (prenhall.com, 2016). Recommendations The three Information Systems that have been recommended for PMF are Decision Support Systems, Transaction Processing Systems and Management Information Systems. Systems such as database management system, payroll system, budgeting system and stock management system are suggested under these Information systems. Also, there are several factors which are recommended to be considered to develop a competitive business strategy. The forces such as choice and preference of the users, preferred cost range, new entries in the market, technological advancements and developments along with the other suppliers should be considered before making an accurate business strategy. Conclusions PMF is a small business that has been serving its customers with pre-packaged meals. With the expansion of the business, it is required to have Information Systems in place such as transaction processing systems, Management Information Systems and Decision Support Systems. Porters competitive model is a five force model that explains five factors that can be utilized for PMF for developing accurate business strategies. Computer networks are also extremely important for communication and collaboration with the stakeholders. However, Information Systems also possess a few challenges and issues in terms of management challenges, social issues and ethical issues. References Chris-kimble.com. (2016).
