Physiology is the study of the anatomical structure and function of the healthy human body and its constituent organs, tissues, and cells.
Physiology and medicine have historically shared much in common.


Hippocrates, the first physiologist and the father of medicine, said, “We are what we eat.
“Food can be both medicine and poison,” he said.
Many drugs used today are made from ingredients derived from foods traditionally known to have beneficial properties.
In this respect, nutrition can be said to have roots with early medicine or physiology.
It is essential for those majoring in food and nutrition to properly understand the healthy human body and understand it in an integrated manner.
Physiology can be said to be a basic discipline that must precede learning about nutrition to maintain health or clinical nutrition and diet therapy to cure disease.

Accordingly, this book focuses on increasing understanding of nutrition and health by providing basic knowledge about the human body so that food and nutrition majors can easily understand physiology and presenting an integrated perspective on the interrelationships of each organ in the human body and life phenomena.

This book consists of a total of 11 chapters.
The first half, Chapters 1-4, deals with the structure of the human body and the maintenance of homeostasis, and the second half, Chapters 5-9, deals with the structure and function of each organ in the human body.
Chapters 10 and 11, the latter part, cover the musculoskeletal system and energy metabolism related to exercise physiology, and are designed to help you prepare for the nutritionist exam.

In each chapter, the authors used various illustrations to enhance understanding of the human body rather than simply memorizing physiological concepts, and briefly summarized the concepts of terms to make them easy to understand.
We hope that this book will serve as a guide to readers' studies and career paths by providing up-to-date knowledge and information on physiology.
