The functions of the skeletal system include:

• support, protection, movement, and production of blood cells

• digestion, absorption, and excretion

• regulation of hormones and enzymes

• transmission of nerve impulses

The functions of the muscular system include:

• Movement, posture maintenance, and heat production

• Blood cell production and mineral storage
