relative stability of the body’s internal environment. Disruptions
to homeostasis often set in motion corrective
cycles, called feedback systems, that help restore
the conditions needed for health and life.

Our fascinating journey through the human
body begins with an overview of the
meanings
of anatomy and physiology, followed
by a discussion of the organization of the
human body and the properties
that it
shares with all living things. Next, you will discover
how the body regulates its own internal environment;
this unceasing process, called homeostasis, is a major
theme in every chapter of this book. Finally, we introduce
the basic vocabulary that will help you speak
about the body in a way that is understood by scientists
and health-care professionals alike.
