Introduction

Human physiology is the study of the functioning of the normal body, and is responsible for
describing how various systems of the human body work. Explanations often begin at a macroscopic
level and proceed to a molecular level. In 1926, Fritz Kahn portrayed the body as a complex chemical
plant, as seen in the painting on the right. This textbook provides an introductory explanation of the
workings of the human body, with an effort to draw connections between the body systems and explain
their interdependencies. A framework for the book is homeostasis and how the body maintains balance
within each system. This is intended as a first introduction to physiology for a college-level course. As
such, some material is deliberately left out (but references will be provided within chapters for students
wishing to learn more).
