1-1. THE SKELETAL SYSTEM
The human skeletal system (see figure 1-1) consists of about 206 bones. The skeleton gives shape and support to the human body. Together with the skeletal muscles, it performs movement of the body. The skeleton, especially the skull and rib cage, provides protection to vital internal organs such as the brain, lungs, and heart. The red marrow in the center of bones produces red blood cells that carry oxygen and nutrients to all parts of the body.
