Unit 1 provide students with a basic understanding of human anatomy and physiology, including its language, the levels of organization, and the basics of chemistry and cell biology. These chapters provide a foundation for the further study of the body. They also focus particularly on how the body’s regions, important chemicals, and cells maintain homeostasis.

28.1: An Introduction to the Human Body
This chapter begins with an overview of anatomy and physiology and a preview of the body regions and functions. It then covers the characteristics of life and how the body works to maintain stable conditions. It introduces a set of standard terms for body structures and for planes and positions in the body that will serve as a foundation for more comprehensive information covered later in the text. It ends with examples of medical imaging used to see inside the living body.
28.2: The Chemical Level of Organization
28.3: The Cellular Level of Organization
Cellular and developmental biologists study how the continued division of a single cell leads to such complexity and differentiation.
28.4: The Tissue Level of Organization
