The book "The Wisdom of the Body" by Prof. Walter B. Cannon explores the physiological balance and homeostasis in the human body. It is the fourth volume in a series of works that have been published over more than thirty years, covering various aspects of bodily functions and responses. The main focus of this volume is on how the autonomic nervous system maintains homeostasis in terms of water, salt, sugar, proteins, fat, and calcium levels, as well as oxygen supply, acid-alkali balance, and body temperature. The author also discusses the natural defenses of the organism, the margin of safety in bodily structure and function, and the role of the sympathetic-adrenal system in homeostasis. The book is written in a clear and engaging style, making it accessible to both the general public and students of biology. It concludes with a summary of bodily stabilization and an epilogue on the relations between biological and social homeostasis.The book "The Wisdom of the Body" by Prof. Walter B.
