The immune system is crucial to the normal functioning of the human body. As the body's 'military', it prevents invaders from entering and destroys those who slip past its defenses. ""The Immune System"" discusses the human body's fundamental defense system, from its component parts to what happens when the body's defenses are breached. Common and uncommon immune disorders are also discussed, as are potential new therapies to enhance or repair the immune system. Packed with full-color photographs and illustrations, this absorbing book provides students with sufficient background information through references, Web sites, and suggested reading for further study.
