Accompanied by colour illustrations and a description of related anatomy, the book provides an integrated explanation of body functioning. It discusses the organisation of the human body, main features and processes that must be controlled for health, the organ systems that act as homeostatic regulators, and effectors of homeostatic regulation. It also discusses influences on homeostasis and provides case studies that place examples of ill health and health care into the context of homeostasis.

Features of the third edition include:

• An overview of microbiology and principles of infection management
• Expanded information on pharmacological principles and actions of the major classes of drugs
• Expanded discussion on physiological functions in relation to specific pathologies
• Updates on how the Human Genome project has impacted healthcare
• Additional case studies to illustrate the healthcare provider's role as an external agent of homeostatic control
• Photographs of common clinical conditions
• Access to an accompanying website with supplemental information
