The Gastrointestinal System For An Intake Of Substance And Extracts The Nutrients From Food

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

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.

The digestive system is made up of all different organs which starts at the mouth and finishes at the anus but on the way involves all other organs; these organs help to break down and absorb the food.

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

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

The small intestine continues breaking down the food and absorbs most of the nutrients. The liver and the pancreas release bile and enzymes into the small bowel to aid in this process. The small intestine joins the large intestine or large bowel, a muscular tube about five feet long. The first part of the large bowel, called the colon continues to absorb water and mineral nutrients from the food matter and serves as a storage place for waste matter. The waste matter left after this process goes into the rectum, the final 6 inches, or so of the large bowel. From there, it passes out of the body through the anus.

Villi and microvilli separate the food particles, which is a physical process. Enzymes are also dumped from liver, gallbladder, and pancreas to help with digestion. Small intestines are divided into three sections; duodenum, jejunum, and ileum. The duodenum produces intestinal enzymes that help to break down nutrients more efficiently in order to ease their absorption in the jejunum and the ileum. Peristaltic contraction plays a great role in moving chyme to the large intestine from the small intestines. Large intestines is comprised of three segments; the cecum, the colon, and the rectum. Food is received in the cecum from small intestines and proceeds into the colon where water is absorbed, and undigested materials are converted into feces. Peristalsis receives the food from colon and stores them before they are expelled through the

The mouth does both mechanical digestion and chemical digestion. Mechanically, your incisors cut food into small pieces, next your canines make the food pieces even smaller, than premolars and molars crush and grind the food, finally saliva moistens the food to a slippery mass. Saliva contains enzymes which speed the chemical reaction in the body, this part is the chemical digestion. Your mouth is the first in your digestive system.

The major stages of the digestive system are ingestion, digestion, absorption, and elimination. Ingestion is the process of taking in food and water into the form of swallowing, and digestions is when the food that was consumed begins to breakdown into smaller pieces so it’s easy to be absorbed into the body. Digestion can happen with two phases, when the food is breakdown by teeth and the second phase which is the chemical breakdown, which is the breakdown of food by enzymes. The next stage of the digestive system is absorption, which absorbs the food of the digestions. The nutrients such as amino acids and simple sugars travel in the blood when then goes to the body cells, that can be broken down more or used to build a cell’s large molecule.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

The digestive system consists of mainly component including the salivary glands, the oesophagus, the stomach and the ileum. All these components play a role in the production of energy to the digestive system. The digestive system is responsible for taking food and water and using enzymes to break up complex molecules into simple soluble materials which are capable of interrelating with the capillaries attached to the cardiovascular

The large,Hollow organs of the GI tract contain a layer of muscle that enables their walls to move. The movement of organ walls-called peristalsis-propels food an liquid through the GI tract and mixes the contents within each organ group. When a person swallows,Food is pushed into the esophagus,The muscular tube that cares food an liquids from the mouth to the stomach. The stomach then stores swallowed food or liquid,Mixes the food and liquid with digestive juice it produces,An then slowly empties it's contents,Called Chyme,Into the small intestine. The large intestine then absorbs water and any remaining nutrients an changes the waste from liquid to stool which is then pushed out through the

The proses of the digestive tract are very complex and difficult to understand. There is a lot of chemistry that ties into the digestion system. There is multiple part of the digestive tract that all have different role helping the body to digestive nurturance. Most people when asked think that the stomach is the place where it all starts but they would be wrong. People also think the that the stomach is the most important but if it comes down to it that with out any part of this complex system the digestion could not take place.

The digestive system are the collection of organs that work together to break down food into nutrients so that it can be absorbed into the blood. This systems consists of four main steps which include ingestion, digestion, absorption, and egestion. The mouth is responsible for carrying out the first step which is taking in the food. The salivary glands, pharynx, esophagus, and the teeth are responsible for the second step as they are responsible to break down the complex food molecules into smaller molecules. The absorption of the food is done by the stomach, the liver, the gall bladder, and small intestines. These organs are responsible for absorbing the digested nutrients and transporting them to the bloodstreams. Finally, the last step, the egestion, is done by the large intestine, rectum, and anus. These organisms are responsible to remove the waste food materials from the body.

Other organs included in the digestive system are teeth, tongue, salivary glands, liver, gallbladder, pancreas, rectum, and anus. Digestive system allows the body break down food into different essential nutrients to be digested. This happens when transformation of vital nutrients and energy that are the important source for nourishing the body and its related functions. (Inner Body, 2016). Stages of digestion involves Ingestion which is the first stage where food intake takes place via the mouth. Then Secretion is when these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile. Swallowing. This process involves smooth and skeletal muscles in the mouth, tongue, and pharynx to shove food out of the mouth via the pharynx into the esophagus.
