This edition: The Skeletal System
The 206 bones of the human skeleton are a miracle of bioengineering. Lightweight and incredibly strong, our bones give us the ability to walk upright, freeing our hands for precise manipulation of objects. See how the skeleton anchors the muscles and protects our essential organs: the heart, lungs and brain. And learn how the bones themselves are chemical factories producing our red blood cells. Join world-renowned surgeon Dr. Mark Reisman as he guides you through the physiology, anatomy and diseases of the skeletal system.
