List and define the 6 main functions of the digestive system: ingestion, movement, digestion (chemical and mechanical), secretion, absorption, and elimination. Ingestion: conscious activity of bringing food and liquid into the digestive system. Movement: occurs by peristalsis (see Q9 for definition of peristalsis).
The intestine ends at the anus.. The function of the intestine is to digest and absorb food. After the initial stages of digestion (chewing and soaking in digestive juices in the stomach) the food enters the small intestine where it is mixed with other digestive chemicals including enzymes. The large molecules of which the food is made are broken down into small, soluble ones.
