Case Study on Acute Gastroenteritis

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

We eat all types of food everyday, we have one important tool that we use to break down food which is enzymes. Digestion starts once food is chewed with saliva found in our mouths. Saliva contains all kinds of enzymes and there are hundreds types of enzymes in terms of breaking down food such as amylase,

The process of digestion first begins in the mouth by in taking food (bolus). The teeth help with masticating (chewing and breaking food particles down) allowing for swallowing and increasing surface area for chemical digestion. Enzymes found in saliva also facilitates with the chemical break down of food primarily starches and fats. The food swallowed then enters into the esophagus (a tube connecting the mouth and stomach). Peristalsis helps the esophagus to push the food in the direction of the stomach. The stomach contents are highly acidic (doesn’t affect the stomach mucosa since cells secrete mucus allowing the stomach wall to be protected) with pH levels between 1.5-2.5 allowing microorganisms to be killed, breaking down of food, and activating digestive enzymes producing a thick substance known as chyme. However, breaking down of foods further occurs in the small intestine consisting of: bile created from the liver, enzymes formed from the small intestine, and the pancreas facilitate with further digestion as well as HCI denatures (unfolds proteins) allowing them to be available to attack by digestive enzymes (also responsible in breaking down the protein). The pyloric sphincter separates the stomach from the small intestine allowing the chime to drop into the small intestine. The small intestine is the primary site for

The stomach is a sac-like organ with strong muscular walls that lies in the upper abdominal cavity just under the diaphragm. The stomach looks small after it is emptied, but it expands

Food is digested by being broken down, by a variety of enzymes, into useful nutrients, which are transported around the body to places where they can be of use, and into waste products, which are excreted from the body. The digestive system is made up of a number of organs, oesophagus, stomach, liver, pancreas, gallbladder, and small and large intestines, these are then separated into the digestive tract and the digestive organs. The digestive tract is, essentially, a single continuous tube that begins at the mouth and ends at the anus, in a fully grown adult it is approximately seven metres long. Food travels through the digestive tract and the digestive organs produce the enzymes and chemicals that are responsible for

Meanwhile, the salivary glands in your mouth are producing saliva, lubricating the food so it can make it’s way down your esophagus and into your stomach. Saliva contains enzymes, substances that make chemical reactions faster and that breaks down large starch molecules into smaller molecules of sugar. The first step of digestion is complete. Once your food gets to your stomach, the stomach starts to furtherly digest your food. Food in the stomach is digested chemically, with chief and parietal cells. Chief cells produce pepsin, which breaks down protein. Parietal cells produce hydrochloric acid (HCI). These cells and their products help to chemically break down food in the stomach. Once food has been mechanically and chemically digested, the food goes into the small intestine duodenum, which  is the upper section of the small intestine. Attached to the duodenum is the pancreas and gallbladder. The pancreas is an organ that produces a variety of digestive enzymes, and the gallbladder is a storage sac that holds the bile produced in the liver. Bile is a chemical that breaks down fat droplets. The duodenum is also the organ that allows nutrients and water to pass through its walls. After completing its rounds in the duodenum, your digested food makes its way down into the small intestine, and then the large intestine. Villi in the small intestines absorbs nutrients into the bloodstream. The large intestine

The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes.

Science Script Introduction; Everyday, we eat and drink, often taking it for granted. Most people disregard what happens within our body during digestion process, So, what really happens in our body when we digest? Scene 1; Mouth Digestion first begins in the mouth, using mechanical digestion. Incisors first bite into the food breaking the polymers into smaller monomers. As the food goes further into your mouth the food is then ground by your molars.

The stomach mixes the highly acidic gastric juices and enzymes with the chyme to prepare the nutrients absorption in the small intestine. The food does not stay in the pancreas, liver, or gallbladder but simply passes by it. These digestive organs aid in the chemical digestion of chyme as it passes into the small intestine. After staying in the stomach four a few hours and passing by the pancreas, liver and gallbladder, it will go to the small intestine (Primal Pictures). Once the food is in the small intestine, it will take three to five hours from entry at the duodenum to exit from the ileum. The small intestine takes part in the further chemical digestion and absorption of the food. The nutrients from the Chinese food will pass through the wall of the small intestine and into the bloodstream so that the nutrients can spread throughout the rest of the body. The surface area for absorption will increase through tiny projections called villi. The unabsorbed portion of the bolus then enters the large intestine. Once the food remains have reached the large intestine it can take up anywhere between 10 hours to several

Carbohydrates are one of the main types of macronutrients that move throughout the digestive system. Starting inside of the mouth, the carbohydrate travels through the body until it gets broken down. The mouth has two forms of digestion, mechanical or chemical. Mechanical digestion includes chewing food, while chemical digestion uses saliva. The salivary glands belong to the accessory organs of the digestive tract, but play a very important role in digestion. They produce amylase, which breaks down the starch amylose and amylopectin into smaller portions. Breaking down starch, is an example of where chemical digestion occurs in the mouth.

When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First, Mastication begins. Mastication is the chewing of the food. A person will crush, grind and tear the food apart. That gets the food ready for deglutition. Deglutition is the swallowing of the mashed up food. When we swallow peristalsis begins. Peristalsis is what happens

Digestion starts in the mouth. Chewing mechanically breaks down the food with saliva. Saliva moistens the food and is an essential enzyme for the digestion of starch. Saliva contains ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. About 10-15 seconds after chewing has begun, the food bolus passes through the pharynx and in the oesophagus. When you swallow, the epiglottis closes to prevent the food from entering the respiratory system. The soft palate closes to prevent food from entering the nasal cavity.

To begin the process of digestion the burger must be chewed up, this is a form of mechanical digestion. The saliva produced is used to break up foods into smaller pieces so it is made easier to swallow, this is using chemical digestion. After being swallowed it travels down the esophagus, at the end of the esophagus is a muscular ring which allows food to enter the stomach. After entering it squeezes shut keeping fluid and food from flowing back up. Inside of the stomach, stomach muscles churn and mix the burger where digestive acids and enzymes are created to help break the burger down into a liquid or paste. Once broken down it leaves the stomach and enters the small intestine. As the thick liquid food

You use your mouth to chew your food, causing it to break down in pieces hence using the process of mechanical digestion, and you also use your mouth to form an enzyme known as amylase, or saliva which breaks down your food chemically, for instance when your saliva touches the bread from your sandwich it begins to form into sugars. Incase you did not know “enzymes are chemicals that are used to break down foods into other chemicals”. Saliva can also help you swallow the food by lubricating and “breaking down the complex carbohydrates into simple carbohydrates.”
