The digestive system is a group of organs that works together to convert food into energy and basic nutrients that will feed the entire body. The digestive system breaks down food so nutrients can be absorbed by the body. The digestive system has three main functions. First, it ingests food then breaks it down so nutrients can be absorbed and it also eliminates what cannot be digested. During an average lifespan, as much as 45 tons of food can pass through one’s digestive system. Food travels almost 9m through a long tube inside the body known as the alimentary canal or the gastrointestinal tract . 1) Mouth: The process of digestion starts in the mouth. Where the food is broken down into small pieces and these pieces can be easily absorbed. 2) Pharynx: The main function of the pharynx is: it allows both air and food to pass through. The pharynx also receives the food in the digestive system after being swallowed and pushes it to the esophagus. 3) Esophagus: Esophagus is a long straight tube which connects the pharynx to the stomach. Once the food has been reduced to a soft mush, the tongue pushes it to the throat which leads to a long straight tube called esophagus. The esophagus squeezes the mass of food with rhythmic muscle contraction called peristalsis which then forces the food to the stomach. 4)Stomach: The stomach squeezes and mixes food with enzymes for hours before it releases the mixture into the small intestine. 5) Pancreas: The pancreas is an oval organ located between the stomach and the small intestine. It makes fluids to protect the small intestine from the acid. It produces important enzymes and hormones that will ... ... middle of paper ... ... ulcers c) Smoking has become increasingly and the chances of ulcers because the procedure of healing is slow, which leads to the recurrence of the ulcer. To develop normally in the colon at the places vulnerable naturally occur under the influence of pressure, where there is a single theory explain why the incidence of this disease is increased pressure in the colon that cause the weakened wall diverticula leading to infection, or blockage in the narrow opening of the diverticulum may reduce blood flow to the area, leading to inflammation. Is a disorder of the digestive system and autoimmunity that leads to the destruction of the lining of the small intestine when eating food that contains gluten, gluten is a form of protein found in grains, and this may cause damage to the intestines to be difficult for the body's absorption of nutrients, especially fat and iron.
•The forty five year old patient is diagnosed with the progressive cirrhosis inflaming the liver along with the parenchymal cells. The plain symptoms is manifested primarily because of the augmentation of edema internally in the lower abdomen.
The last parts of the large intestine are the Rectum and the Anus, the rectum is responsible for the excretion of faecal matter from the body while the anus is the actually ring of muscle at the end of the rectum which allows for the passage of waste material to exit the body.
The first part is called the duodenum, in here chemical degradation of chime starts here. It is caused by the enzymes secreted by the duodenum and the pancreas. Bile which is produced by the dog’s liver and stored in the gallbladder helps to break down the fats and helps to neutralise acid from the stomach. The second and third part of the small intestine for the dog is the jejunum and ileum. The jejunum and ileum surface area increase due to the plica circular folds which carry villi.
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
In order for this breakdown to happen, the ‘tube’ through which the food travels requires assistance from a number of other digestive organs starting with the salivary glands, and later receiving
Peristalsis that was mentioned earlier in the oesophagus is also used in the small intestine to help move food through and mix it with digestive secretions from the pancreas and the liver. Its first responsibility is the process to continuously breakdown, then the second and third responsibility is the absorption of nutrients into the bloodstream. As chyme moves through the small intestine, many of the molecules are absorbed in to the bloodstream and the small intestine has a very efficient way to help in this process. The inside of the small intestine has finger-like projections called villi and these raise the surface area of the gut. The contents of the small intestine begin semi-solid and then finish in a liquid form after passing through the organ. Bile enzymes, water and mucus contributes to the change in consistency. Then once the nutrients have been absorbed and any leftover food residue liquid has been passed through the small intestine, it will then move onto the large intestine through the ileocecal
This pear shaped organ contracts while we eat, then sends bile to the small intestine (WebMD (2).)
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
The pharynx is a large cavity behind the mouth and between the nasal cavity and larynx. The pharynx serves, as an air and food passage but cannot be used for both purposes at the same time, otherwise choking would result. The air is also warmed and moistened further as it passes through the pharynx. The larynx is a short passage connecting the pharynx to the trachea and contains vocal chords. The larynx has a rigid wall and is composed mainly of muscle and cartilage, which help prevent collapse and obstruction of the airway.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
It holds a juice that contains digestive enzymes like trypsin,it helps digest protein foods, the juice is called, pancreatic juice. It also holds amylase and maltase, they mash down carbohydrates. And finally it also holds lipase, it works with bile from the liver to digest fat. Bile is made in the liver but held in the gallbladder, a little pitted organ found just below the liver. Bile does not have enzymes instead, it holds mostly acids, salts, cholesterol, and other materials that work with lipase to break down fats.
A digestive system is where the food is passed through the animal’s body, as is broken down and used for different and specific reason to the animal. There are 3 main digestive systems; these are Monogastric (carnivore), Hindgut Fermenter and a Ruminant. Each of these digestive systems digests foods using nearly the same organs, but for different functions.
Hi there. My name is Albert and this is my adventurous story of my journey through a human. I was a delicious gourmet hamburger with fresh ingredients like salad, mustard and an angus beef pattie. I was dumped into a family feed box labelled with a massive golden arched ‘M’. Now, I’m quite an intelligent burger, unlike my other food companions and I love studying about the fascinating human digestive system when I went to Burgerton College. I’m here to tell you first-hand about my digestive journey into the human body! Here is a map of the human digestive system for your convenience to pinpoint where I am in my journey as I am recounting my story.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
