The human body is a complicated and beautiful machine, governed by the laws of physics and chemistry. By understanding its physiology - how it performs its varied functions - it is possible to build strategies for diagnosis, treatment, and prevention of disease. In this extensively-revised edition, a new structure, additional learning features, and an expanded use of artwork, make Human Physiology even more student-friendly than its predecessors. Human Physiology provides clear explanations of the principles that govern the body's physiological processes and shows how these can be applied. This is the ideal course companion for any student needing a solid foundation in the subject for a future career in human biology, biomedical science, or medicine.
