Answer:
1. Support
2. Protection
3. Movement
4. Supply & Storage
Explanation:
1. Support : It provides a framework to support the organs and tissues of the body.
2. Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).
3. Movement: It provides a framework for muscles to attach. Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.
4. Supply & Storage: The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
