Digestive System and the functions

Digestive systems take many forms. Some organisms, simply secrete biotoxins and digestive chemicals (eg, [enzymes]) into the extracellular environment prior to ingestion of the consequent "soup".The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food.Organs that make up the digestive tract are the mouth, esopahgus, stomach, small intestine, large intestine, rectum and anus. MOUTH
Digestion starts here when you start eating. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a porridge substance so that your body can absorb and use. ESOPHAGUS
The esophagus also know as the gullet,receives food from your mouth when you swallow the food. By muscular contractions called peristalsis, the esophagus delivers food to your stomach. STOMACH
The stomach is also know as hollow organ, that holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are done procesing,they are released into the small intestine.

SMALL INTESTINE
The small intestine is a long muscular tube that breaks down food using its enzymes. Peristalsis also is at work in this organ, moving food through and mixing it with digestive secretions from the 'friends' which is the pancreas and liver.

Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or otherwise known as the colon.

LARGE INTESTINE ( COLON )
The large intestine is a long muscular tube that connects the small intestine to the rectum. The large intestine is a highly specialized organ that is responsible for processing waste so that emptying the bowels is easy and convenient.It is also the last organ in the digestive system which is needed in disgestion

Stool, or waste left over from the digestive process, is passed through the large intestine by means of peristalsis, first in a liquid state and ultimately in a solid form. As stool passes through the colon, water is removed. It normally takes about 36 hours for stool to get through the colon. The stool itself is mostly food debris and bacteria. These bacteria perform several useful functions, such as synthesizing various vitamins, processing waste products and food particles, and protecting against harmful bacteria. When the descending colon becomes full of stool, or faeces, it begins to get rid of all the wastes.
