What is it?
The digestive system consists of the digestive tract, a series of hollow organs to form a tube from mouth to anus. Furthermore, the digestive system is made by other organs (liver, pancreas and gallbladder) that help the body digest and absorb food.
Parts of the digestive tract
The digestive tract consists of the mouth, esophagus, stomach, small intestine, large intestine (colon), rectum and anus. The interior of these bodies is hollow and is lined with a mucus layer. The mucosa of the mouth, stomach and small intestine presents a series of glands that produce juices that help digest food. Under the digestive tract mucous layer has a sheet of muscle that contract and relax to produce a movement called peristalsis, which helps move the food to the length of the tube. The movement of these walls pushes food and liquids. Read the rest of this entry »
The term refers to the crushing digestion and subsequent breakdown of the body supplied food into its component parts. This process is necessary so that the nutrients in the blood can be passed from the bowel. With the nutrients enter the blood stream then into the individual cells.
Digestive enzymes help to divide the food.
The first step in digestion is carried in the mouth. A thorough and sufficiently long chewing of food is needed to crush the recorded food sufficiently. Only with sufficient mastication, the saliva mixed with sufficient food. This contains an important enzyme called amylase which digest the carbohydrates taken responsible for.

Digestion is the process in which the body converts food into usable components. Digestion begins in the mouth when we chew food, and is in the stomach and the intestines continued by chemical cleavage. This is done by using special proteins, the digestive enzymes.
Digestion is the metabolic rate. This process is referred to the following:
Processing in the digestive organs
Transport of food nutrients and functional carrier substances in the blood
Cell structure and excretion of waste products.
The complete digestion of a balanced meal takes about 24 hours. The food remains the next four hours in the stomach happens, then within six hours the small intestine and passes in six or seven hours the large bowel. After an equally long “stopover” in the rectum, the indigestible food residues excreted. These are just average times – the digestion of a meal always depends on its composition, physical movement and mental health from. The quickest way to digest carbohydrates – ideally in the form of fiber-rich foods – fats do, however the longest.
