Description:

Eating and drinking are two of the great pleasures of life, but we rarely stop to think about the winding road that our food must follow through the many complex structures of the digestive system. The digestive tract, also called the gastrointestinal, or GI, tract is a tubular system that involves a number of different organs and tissues. Its main purpose is to break down food into small molecules that can be absorbed by the cells of the body. This process is called digestion. This learning program will introduce you to digestion. It starts where the process begins—in the mouth—and follows the path taken by food through the rest of the digestive system, including the pharynx and esophagus, the stomach, and the small and large intestines. Along the way, you will also learn about the accessory organs that aid in digestion.

Upon completion of this learning program, you will be able to:

  • Describe the intake and digestion of food in the upper GI tract.
  • Identify the roles of the accessory organs in digestion.
  • Describe the digestion and absorption of food in the intestines.
  • Describe the formation and expulsion of feces.
  • Recall the nerve systems of the GI tract.
