HOW DOES THE DIGESTIVE SYSTEM WORKS?

Whitout this system , the body would not be able to obtain energy and nutriens

Saliva begins to form in your mouth .Once the food is swallowed it goes down the esophagus

. Then, the muscles of the esophaghus push the

food down into the stomach .Atached to the end of the esophagus is the stomach where the food mix up into a pulp.

HOW DOES THE DIGESTIVE SYSTEM WORKS?

From the stomach the pulp goes into the small intestine –starts at the end of the stomach. Here the nutriens from the food pass into the blood .

After that most of the nutriens are removed from the blood mixture(There is lest over ). The large intestine pushes the waste into the rectum. Here, feces are formed.
