• 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
