18. The skeleton gives shape and support to your body. • Bones protect your internal organs. For example, ribs surround the heart and lungs, and the skull encloses the brain. • Major muscles are attached to bone and help them move. • Blood cells are formed in the center of many bones in soft tissue called red marrow. • Major quantities of calcium and phosphorous compounds are stored in the skeleton for later use. Calcium and phosphorus make bones hard
