Functions of the skeletal system

Support

Bones of the limbs and vertebral column support the body
The mandible and maxilla support the teeth
Some viscera are supported by nearby bones

Protection

Bones enclose and protect the brain, spinal cord, heart, lungs, pelvic viscera, and bone marrow

Movement

Limb movements, breathing, and other movements are produced by the action of muscles on the bones
Act as lever

. Electrolyte balance

The skeleton stores calcium and phosphate ions and releases them into the tissue fluid and blood according to the body’s physiological needs.

Acid–base balance

Bone tissue buffers the blood against excessive pH changes by absorbing or releasing alkaline phosphate and carbonate salts.

Blood formation

Red bone marrow is the major producer of blood cells, including cells of the immune system.

. Hormone secretion

Bone cells secrete hormones that influence the secretion and action of insulin and moderate the stress response.
