Anatomy & Physiology, Third Edition answers the demand for a leaner version of Elaine Marieb and Katja Hoehn's Human Anatomy & Physiology with less in-depth coverage of pregnancy, heredity, and the developmental aspects of various body systems, while keeping basic themes such as homeostatic imbalances strategically in place. This revised edition includes major updates to the content and figures based on current research findings. The text's all new muscle art features more realistic, natural looking colors and textures, and its new "Check Your Understanding" questions follow major sections within each chapter and serve to reinforce and test students' understanding of the major concepts of the section. Elaine Marieb's instinct for providing colorful, dynamic explication of body-system anatomy & physiology creates a focused presentation of basic principles. For this new edition, Dr. Marieb has teamed up with co-author Katja Hoehn to produce this exciting text featuring extensive art development, text revisions, and thoroughly updated supplements and media resources.
