Excretory and Digestive System

By : Nash Tannehill

Digestive System

The function of the system is to convert food into energy and nutrients to feed the body. It starts in the mouth where the food is chewed up, next it goes down the esophagus where its pushed down to the stomach. The stomach breaks down the food so its easier for the small intestines to absorb the nutrients. The large intestines absorbs the water from the remaining indigestible food and then finally to the anus where its excreted.

Helping in digestion

First of all, the liver metabolizes your food and stores nutrients within the body. Secondly, the pancreas converts the food into fuel for your cells. Lastly the gallbladder holds bile produced in the liver until it is needed for digesting fatty foods.
