Formation of Joints for Movement

Bones provide anchors for muscles to attach. Tendons attach muscle to bones. Muscles pull on bones to create movement.

Blood Cell Production

Bone marrow produces red and white blood cells and platelets. Red blood cells carry oxygen. White blood cells fight infection. Platelets clot blood.

Store of Minerals

Calcium and Phosphorus are stored in the bones to keep them strong.
