What is Digestive System?


What do you understand by Digestive System?

The answer to this is digestive system is a sequence of unfilled organs joined in a long, distortion tube from the mouth to the anus. The inner part of this tube consists of a coating called the mucosa.

Mucosa includes tiny glands in the small intestine, mouth and stomach that fabricate juices to help in digestion of food.

Two more digestive organs are present in the body namely liver and pancreas which creates juices that reach intestines through small tubes. Besides this, fraction of other organ systems like nerves and blood has a very important and drastic role in the functioning of digestive system.

Another question which comes in the mind is that how digestion of food takes place?

The appropriate answer to this question is that it engages the mixing of food, its faction through the digestive zone, and large molecules of food chemically breaks down in small molecules.

When we masticate and gulp down food, digestion start functioning in the mouth and it is accomplished in the small intestine.

The large, unfilled organs of the digestive system consists muscles that facilitate their walls to move. The movement of organ walls can push food and liquid and also can mix the filling with each organ.

Archetypal movement of the esophagus, stomach and intestine is known as peristalsis. The muscle of the organ creates a thinning and then pushes the thinner portion slowly down the length of the organ.

Food and fluid are shoved in front of them through each vacant organ of narrowing waves. Three tasks are performed mechanically when food enters the stomach. Firstly, food and liquid consumed must be stored by the stomach. Secondly, Stomach produces liquid, food and digestive juices which need to be mixed up. The last and the foremost thing is to filter and empty its contents gradually into the small intestine.
