Five Functions of Skeletal System

The skeletal system forms the physical foundation of the body and is composed of the bones and moveable and immovable joints.

The primary functions of the skeletal system are to:

• Give shape and support to the body

• Protect various internal structures and organs

• Serve as attachments for muscles and act as levers to produce body movement

• Help produce both white and red blood cells (one of the functions of bone marrow)

• Store most of the body’s calcium supply as well as phosphorus, magnesium, and sodium.
