Human Digestive System

In the digestive system, food is taken in through the mouth, broken down into small particles, and passed through the esophagus into the stomach. Stomach acids then digest a small portion of the proteins and a somewhat larger portion of the starches, passing the food into the small intestine, where the majority of the digestive process takes place. The eventual elimination of waste products drawn from the food is carried out through the lower, or large, intestine, the kidneys, and the excretory organs; this process results from the work of the digestive system but is not technically a part of it. Digestion is essential to maintaining good health; the substances processed by the digestive system must also contain sufficient nutrients to provide sufficient fuel. Quantity is not enough.

Raymond L. Powis notes that, before scientists had determined the nature and workings of the digestive system, "its role in human affairs was subject to all sorts of interpretation" (171),
