Chapter 1. The Human Organism
Basic chemical characteristics are responsible for the structure and functions of life. Cells are the
basic structural and functional units of organisms, such as plants and animals. Organelles are small
Chapter 9. Muscular System
Muscles are responsible for movement of the arms, legs, heart, and other parts of the body;
maintenance of posture; respiration; production of body heat; communication; constriction of
organs and vessels; and heartbe
Chapter 2. The Chemical Basis of Life
Atoms consist of protons, neutrons, and electrons. Protons are positively charged, electrons are
negatively charged, and neutrons have no charge. Protons and neutrons are in the nucleus;
electrons are loca
Chapter 6. Skeletal System
The skeletal system consists of bones, cartilage, tendons, and ligaments. The skeletal system
supports the body, protects the organs it surrounds, allows body movements, stores minerals and
lipids, and is the site of
Chapter 3. Cell Biology
The plasma membrane forms the outer boundary of the cell. The nucleus directs the cell's
activities. The cytoplasm, between the nucleus and the plasma membrane, is where most cell
activities take place. Cells perform th
