Presenter, Liz Fraser.

Look at the mechanics of the body's internal defense system. Distinguishes passive immunity from the body's active lines of defense: the skin and its secretions, the inflammatory response, phagocytes, and lymphocytes. Uses case studies involving chicken pox, tetanus, and tuberculosis to show different ways in which the human immune system seeks to protect the body from infection. Introduces immune system hypersensitivity and failure through case studies involving asthma and HIV.
