1-6. REGIONS OF THE HUMAN BODY (FIGURE 1-1)
The human body is a single, total composite. Everything works together. Each
part acts in association with ALL other parts. Yet, it is also a series of regions. Each
region is responsible for certain body activities. These regions are:
a. Back and Trunk. The torso includes the back and trunk. The trunk includes
the thorax (chest) and abdomen. At the lower end of the trunk is the pelvis. The
perineum is the portion of the body forming the floor of the pelvis. The lungs, the heart,
and the digestive system are found in the trunk.
