The skeletal system is like the framework of a house. The bone system offers a variety of things such as storage, "support, and protection" to the other four systems (Van DeGraaff and Fox 205).

It offers a place of "insertion and origin" for muscles and supports their shape (Britannica Electronic Encyclopedia). The spinal cord an extension of the central nervous system; is protected and comfortably cushioned inside the spinal column.

The muscular system allows for "voluntary and involuntary" movements (Chabner 521).

This system allows for the collection of food to nourish the body. The body would starve it were not for the muscular system. The "heart" is a muscle that nourishes the body at the tissue level (Columbia Electronic Encyclopedia). The muscles provide a cushion for internal organs also.

The circulatory system provides the "necessary properties for life" (Columbia Electric Encyclopedia). He heart pumps the blood throughout the body, which carries oxygen to bones, muscles, nerves, and organs. "Oxygen" provides the muscles with the fuel they need to survive and function properly (Chabner 346).

In the same time, the circulatory system protects the against blood loss when vessels...
