Human Digestive System Anatomy
Objectives:
1. Learn the anatomy of the digestive system. You should be able to find all terms in
bold on the human torso models.
2. Relate structure of the system to some of its functions.
I. Introduction:
Some terms used to describe the relative positions of body parts are used
repeatedly throughout the lab, and appear in a glossary at the end of this exercise.
II. a. EXTERNAL ANATOMY
The trunk of mammals is divided into a thorax, which is bordered by ribs, and an
abdomen. Most of the digestive system
is within the abdomen,
but the head, neck, and
thorax contain the superior end of the digestive system.
