Functions of the Skeleton

FUNCTIONS OF THE SKELETON

1.           Provides a framework that supports the body; the muscles that are attached to bones move the skeleton.

2.           Protects some internal organs from mechanical injury; the rib cage protects the heart and lungs, for example.

3.           Contains and protects the red bone marrow, the primary hemopoietic (blood-forming) tissue.

4.           Provides a storage site for excess calcium. Calcium may be removed from bone to maintain a normal blood calcium level, which is essential for blood clotting and proper functioning of muscles and nerves.
