The Digestive System

The offerive System why is it that 1 in 3 life-sized number perhaps even much on a fixedness basis battles some kind of digestion problems? Understanding how the digestive remains whole caboodle ordain attention to run into why digestive problems argon so greens. The digestive outline is to a greater extent than digest and bowels. It is a placement of organs that plaits solid viands into energy and is one of the or so signifi offert forges the consistence hammer outs. There atomic number 18 more(prenominal) reasons that cause so some(prenominal) people to pain with digestive problems. tercet of the virtually greens reasons be the pretermit of k this instantledge of how the digestive arranging works, scurvy nutriment and undiagnosed health check sort outs. drop of have a go at itledge of how the digestive arrangement works is one of the umpteen reasons that cause digestive problems. The digestive organization is uniquely constructed to perform its specialized map of turn a directioning forage into the energy and ex foldering food for thought for thoughts necessary to sustain life. It does this by floping graduate aliment into its basic nutrients, which imply vitamins and minerals, fats, carbohydrates, proteins and piss, before transporting them to the teensy intestine, where to the blueest degree of the nutrients atomic number 18 assumeed into the schema.The digestive system comebacks place in the alimentary plentyal, a vacuum tube that runs from the mouth to the anus and includes the o oesophagus, resist, subtile intestine, and heavy(a) intestine, colon and rectum. The coloured and pancreas a care run to digestion, nevertheless ar not ingredient of the alimentary plunderal. Digestion begins in the mouth, where chemical and mechanistic digestion occurs. nutrient inters the mouth and is chewed by the teeth, kindlecelled over and mixed with saliva by the tongue.The sensations of smel l and taste from the diet for thought sets up reflexes which stimulate the salivary glands, saliva is produced by the salivary glands and is released into the mouth. Saliva begins to break down the food, moistening it and making it easier to s skirtow and contains a digestive enzyme called amylase which breaks down the carbohydrates (starches and sugars). One of the near Coperni screwing functions of the mouth is chewing. Chewing breaks the food into pieces and al down in the mouths food to be mashed into a fragile mass that is easier to swal start and digest later.Movements by the tongue and the mouth push the food to the back of the throat for it to be swallowed. A flexible flap called the epiglottis closes over the trachea to ensure that food calculates the esophagus and not the wind pipe to keep on choking. in one case the food is swallowed, it enters the esophagus, a muscular tube that is located between the throat and the stomach. Food is move by peristalsis which pus hes the food down by means of the esophagus to the stomach. The stomach is the widest part of the alimentary wadal and acts as a reservoir for the food where it whitethorn remain for between 2 and 6 hours.The stomach has 3 main functions to lineage the swallowed food and liquid to mix up the food with various hormones, enzymes, including pepsinogen which begins the digestion of protein, hydrochloric acid, and an separate(prenominal) chemicals and to easy empty its content into the lessened intestine. The wall of the stomach is impermeable to most substances, although it does ingest some water, electrolytes, certain drugs, and alcohol. At even intervals a circular muscle at the lower reverse of the stomach, the pylorus opens allowing low-spirited amounts of food, now known as chyme to enter the scurvy intestine.Most digestion and absorption of food occurs in the fine intestine. The small intestine consists of 3 split the duodenum, the jejunum, and the ileum. The small intestine has 2 important functions. First, the digestive process is undefiled here by enzymes and other substances do by intestinal cells, the pancreas, and the liver. Second, the small intestine absorbs the nutrients from the digestive process. The inner wall of the small intestine is cover by millions of footling finger like projections called villi. The villi ar covered with tinier projections called microvilli.The combination of the two allows absorption of nutrients to occur. ununderstood material travels next to the cosmic intestine. The large intestine is to remove water and salts from the undigested material and to form solid consume that net be excreted. Bacteria in the large intestine help oneself to break down the undigested materials. The remaining contents of the large intestine atomic number 18 moved toward the rectum where feces argon stored until they leave the dead proboscis through the anus. The anus is the last part of the digestive tract. Accessory d igestive organs which include the pancreas, liver and gall ladder are not part of the digestive tract or also known as the alimentary canal, but play an important role in the digestive process. The pancreas produces enzymes that help digest proteins, fats and carbohydrates it also makes sodium hydrogen carbonate which neutralizes stomach acid. The liver produces gall, which helps the trunk absorb fat and it also regulates substances in the fall cells. The gallbladder stores bile until it is necessityed. The enzymes and bile produced by these organs move through ducts into the small intestine where they help breakdown food.The nutrients from the small intestine travel through the air to the liver, which help process the nutrients. digestive problems results from suffering nutrition. commodity nutrition is inborn for preventing decent process of the body systems especially the digestive system. Eating a well-balanced, nutritious diet and controling a healthy life-style a re the best ways to prevent digestive problems and illnesss (Lipski, 2005). The kinds and amounts of food a person take in and how the digestive system processes that food plays pro show roles in maintaining trusty health and preventing common digestive problems.Since the digestive system is accountable for breaking down food into nutrients that can be absorbed by the body and used for fuel, growth and cell repair. Good nutrition is essential for maintaining kosher functions of the body systems. Generally, health experts recommend eating roughage to help prevent constipation and diarrhea. down fats and oils which can slow down digestion. They also suggest drinking plenty of water which helps lubricate food eat up so that it passes more easily through the alimentary canal, it helps soften stool which may prevent constipation.Water also helps dissolve minerals, vitamins and other nutrients, there by facilitating their absorption by the bodys tissues. Good nutrition is not onl y essential for maintaining proper function of the body systems it is also essential for maintaining homeostasis of the body systems. The body needs unspoiled nutrition for the body systems to decent function correctly. The digestive system does assist with homeostasis merely it can not accomplish it alone. in all organs systems work unneurotic to maintain homeostasis. The digestive system provides the nutrients needed for the circulative system.As the food moves through the stages of digestion (mechanical, peristalsis, chemical) it is distressed down into simple water- alcohol-soluble molecules that can cross cell membranes. Since the circulatory system is the transportation system of the body it transports takes, gases, hormones, electrolytes and nutrients from smashing nutrition to and from the body cells. It also transports water to and from the tissues. So as these molecular-sized, water soluble particles pass through the cell membranes of cells in the digestive tract and pass through the walls of capillaries the nutrients are picked up by the line for transport. line of products in the capillaries carries the nutrients to all the cells in the body. Red seam cells, White crosscurrent cells, and Platelets and Plasma all help to maintain homeostasis. Red blood cells transport type O and hydrogen ions throughout the body. White blood cells fights transmittals and platelets assist in blood clotting and the plasma transports the blood cells. None of these occasions can function without the nutrients supplied by the digestive system. Blood also maintains homeostasis of water, electrolytes and body temperature all by acquire the nutrients necessary to function from the digestive system.The digestive system needs bully nutrition to keep it functioning properly and all organs systems working to spawnher properly to maintain homeostasis. Undiagnosed median conditions will cause digestive problems if leftfield untreated and is one of the most com mon reasons that so many a(prenominal) people suffer with digestive problems. Nearly everyone suffers from heartburn and dyspepsia now and then and these might be normal side effects of digestion, but when they occur often it might be signs of a problem and should comport aesculapian attention.Seeking medical checkup attention or being seen by a medical doctor will help to show if the heartburn or upset stomach are from normal side effects of digestion or whether any mechanical factor much(prenominal) as a hiatal herniation or even silent ulcerations of the esophagus, stomach, or duodenum by chance causing the digestive problems. A hiatal hernia and silent ulcers if left untreated could turn into a estimable problem which can cause bleeding, pain, scarring and difficulty in swallowing and can cause a chronic condition with complications.Treatment of heart burn and saloon of its complications are almost always medical, not surgical procedures these days and, if followed f aithfully are very effective. Peptic ulcers is another serious problem that many people have and do not even know it, one might mistaken them for heartburn, stomach upset and nausea. The pain and discomfort comes and goes and sometimes durable for days or even weeks. An ulcer can be treated by medication and usually takes virtually 8 weeks to completely heal.If left untreated it can cause internal bleeding and more severe damage that might need surgical repair (Monroe, 2000). The digestive system is a complex system. There is a lot of information that we know about this system and so much more that is still unknown. For example, for many years the American Heart Association has recommended taking acetylsalicylic acid to prevent heart attacks and strokes. Now, there appears to be a downside to taking a low dosage of aspirin free-and-easy. According to look into taking a daily aspirin can cause serious problems in the digestive system.Research shows that people who take aspiri n are at chance for excess gastro-intestinal bleeding or ulcers that perforate. So the question is does the risk balance the well-being? Through inquiry they have found out that there are three factors that particularly affect developing gastro-intestinal complications they are the increased risk, male gender and ulcer history. All of those things are doubled when a person takes a daily low dose aspirin and the complications can be serious including death. In fact quintette to ten percent of people with these complications will die from it.Research has proven that the thing that is in aspirin that causes these problems is the same thing that prevents heart disease and the same prostaglandin changes are the ones that somehow enhance the probability of developing GI irritation that can move to bleeding, that can lead to perforation. So research has taught us that there is a high risk of developing gastro-intestinal complications including bleeding or ulcers that perforate, wit h the use of a low daily dosage of aspirin especially in the male gender and in those with a past history of ulcers.Through this research we still do not understand why the risk is much high for the male gender than the female gender, that riddle is still unknown. Reasons that cause so many people to suffer with digestive problems are the lack of knowledge of how the digestive system works, poor nutrition and undiagnosed medical conditions. The most obvious solution to maintaining good health and preventing digestive problems would be getting to know the digestive tract and taste how it works, maintaining a healthy diet and lifestyle and seek medical attention alternatively of letting the digestive problem turn into something much worse.The Digestive SystemThe homosexual body consists of number of organ systems which work collectively to execute functions of the body. The three most important human organ systems are circulatory, digestive and endocrine system. The main function of the digestive system is to process food in much(prenominal) a way that the energy molecules are absorbed by the body and the residues are left out. The physiological processes which are required for the digestive system are absorption, digestion, motility, secretion and excretion (Margaret E. Smith, 2001) Digestive System Digestive system helps the body to maintain stability, equilibrium or balance.Digestive system contributes in homeostatic regulation of the body. The body would suffer if there is no regular supply of energy and nutrients from digestive system. The digestive system helps in absorption of ions, vitamins, positive substances and water that is necessary to the body. When the food is chewed and swallowed, the food is broken down in the digestive tract to very small nutrient molecules which can be easy to enter into the villi of small intestine. (Rebecca L. Johnson, 2004) Digestive enzymes are organize by the pancreas and the digestive tract.Besides this, the liv er produces bile which is stored in the gall bladder to digest the fats. By the use of hepatic portal vein, blood passes from smaller intestine to the liver i. e. , in to the circulatory system. The liver is the alert organ of homeostasis and it monitors the blood. The liver produces urea by breaking down toxic substances like alcohol and other drugs. After eating, the liver stores glucose as glycogen and produces plasma proteins. coloured keeps the blood glucose concentration constant by releasing glucose in between eating. This is how the digestive system works along with the other systems which include circulatory system.Organs in the Digestive system There are several(prenominal)(prenominal) organs in the digestive system. The digestive system can be dissever in to two systems. They are pep pill gastrointestinal tract and lower gastrointestinal tract. The upper gastrointestinal tract consists of several organs like mouth, vocal cavity, pharynx, esophagus and stomach. The l ower gastrointestinal tract consists of small intestine, ileum, large intestine, anus and rectum. (Cheryl Jakab, 2007) The functions of some important organs include Oral Cavity The oral cavity or the mouth is the starting part of the digestive system. It accepts food by way of ingestion.Here, the food will be broken in to smaller pieces and get mixed with saliva. Saliva helps as lubrication for the food particles. The oral cavity consists of different parts which are helpful in the digestive system. They are tongue and teeth. lessened intestine The small intestine is about 35 millimeteres in length and grayish royal in color. The small intestine is the lasting intestine which is six to seven meters long. The small intestine has the general structure of the GI tract. The small intestine consists of exocrine cells in the mucosa which secretes peptidase, mucus, maltase, sucrose, lipase, maltase and enterokinase.Endocrine cells secrete secretin and cholecystokinin. The process of digestion is perfect by the small intestine. It absorbs the nutrients and sends the residue to large intestine. The gall bladder, liver and pancreas are important organs in the digestive system which is closely related to the small intestine. Small intestine is divided in to duodenum, jejunum and ileum. The small intestine helps in several functions such as hormone secretion, intestinal juice secretion, ninety percent absorption, forward actuation of contents and it is the major site of digestion.Rectum The rectum can be found in the last(a) portion of the large intestine which connects to the anus and it is a muscular tube like structure. The waste is stored here and permits expulsion when pressure on the rectal walls is caused. Anus The anus is formed by the out layers of the body, skin and the intestine. The anus is the opening at the end of the digestive tract through which the waste matter is ejected from the body. There are many diseases which are caused due to the imprope r functioning of the digestive system. The most specific disease is the Ulcer.Ulcer is the disorder caused in the upper digestive tract. Ulcer can be develop in the duodenum, lower part of the esophagus and in jejunum. There are many causes for ulcer. Some of them include certain medications, infection and disorders caused by the over secretion of stomach juices. The symptoms of gastric ulcer include burden loss, feeling heart burn and indigestion and gastrointestinal bleeding. Most of the patients suffering from ulcer suffer from bleeding which results in regurgitation blood, anemia or blood through rectum.
