Human Digestive System

What is the Digestive system?
The human digestive system is a complex serial publication of organs and glands that workes feed. In order to use the food we swallow up, our frame has to extravasate the food dispirited into smaller molecules that it can process; it also has to excrete waste.Most of the digestive organs (like the stomach and intestines) ar tube-like and contain the food as it makes its way through the body. The digestive system is essentially a retentive, twisting tube that runs from the rima oris to the anus, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals.
What Is the Function of the Digestive System?

Structure of Human Digestive System
* Mouth

The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first flake of food.



Chewing breaks the food into pieces that are more easily digested, trance saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
* Esophagus

rigid in your throat near your trachea .and it is a long tube that runs from the mouth to the stomach It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when were upside-down.
* Stomach

The stomach is a excavate organ, or container, that holds food while it is being mixed with enzymes that get across the process of breaking down food into a useable form. Cells in the lining of the stomach secrete a grueling acid and powerful enzyme that are responsible for the breakdown process....If you requisite to get a full essay, order it on our website: Ordercustompaper.com
