The Sixth Edition of Human Biology  maintains the same central organizing theme of homeostasis presented in previous editions to present the fundamental concepts of mammalian biology and human structure and function. Renowned author, Daniel Chiras, approaches the scientific process in a truly engaging way that asks students to become deeper, more critical thinkers. The focus on health and homeostasis allows students to learn key concepts while also assessing their own health needs. The inclusion of recent findings on such newsworthy topics as trans fats, overconsumption, vitamins, vaccinations, cancer prevention, And The USDA Food Pyramid piques student interest and provides them with the information relevant to making informed health decisions in their own lives.

The Student Study Guide includes chapter overviews, outlines, learning objectives, study tips, art labeling exercises, and practice tests.
