Digestive System

MCAT Anatomy > Human Body Systems > Digestive System


The mouth to the anus is one continuous tube that is partitioned by sphincters. The path that food takes starts in the oral cavity, where the bolus is passed into the pharynx, then the esophagus and eventually where it enters the acidic stomach to be dissolved.

The chemical mixture from the stomach is sent through the small intestine where digestion is aided by the pancreas, gall bladder and liver. It moves from the small to the large intestine where the waste products are eventually excreted out of the anus.
