Defense Mechanisms DVD

About this program:

The human body is under constant threat from a hostile environment; parasites, bacteria, and viruses are always present and ready to attack.

When the body is unable to adapt to or overcome these threats, illness results.

This program examines both such natural barriers to attack as the skin, which is the first line of defense, as well as internal defense mechanisms like the immune system.

The program illustrates graphically how disease occurs.
