Immunology and Homeostasis

This unit covers the basics of how the body defends itself against invaders of all kinds. As you will discover, our immune system is quite robust and innovative. Homeostatic control will be studied by looking at critical systems that do this: temperature regulation system, water balance, waste disposal, and the excretory system.
