human body, the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems. Human anatomy and physiology are treated in many different articles. Physiology is the study of normal function within living creatures.

Understanding the Context

It is a sub-section of biology, covering a range of topics that include organs, anatomy, and biological compounds, among others. Physiology is the biological science that studies how living organisms and their parts function. While anatomy describes what the body looks like and how it’s structured, physiology asks the next question: how does it all actually work? Introduction: In this and the next Basic Physiology chapter, we discuss in more details two types of cells in the body that demonstrate several basic physiological principles that are very useful to know and to understand before studying specific organ systems.
