- The first concise textbook on the topic of physiological circuits, it provides basic principles or ‘laws’, and then derives why physiology is built the way it is, and why certain diseases happen while others don’t.

- By the end of the book you will be able to use simple but powerful mathematical models to describe physiological circuits, turning details into useful understanding and new ways of thinking about treating diseases, including diabetes, autoimmune diseases, and age-related diseases such as lung fibrosis and cancer. The book explores (i) hormone circuits, (ii) immune circuits, and (iii) aging and age-related disease, and culminates in a periodic table of diseases.

- It is written in a very accessible style, suitable for anyone with a background in a STEM subject (including biology, engineering, physics, math, engineering, computer science, chemistry or other subjects).
