Full Answer

The skeleton gives the body shape and protects its internal organs. The brain is housed inside the cranium, or skull, and is protected by the skull in the event of any trauma to the head. Likewise, the heart, lungs, liver and other internal organs are housed in the rib cage and protected from trauma by the ribs. The bones of the spine hold the body straight, enabling upright forward motions such as walking and running, notes PT Direct.

The body's muscles attach to the skeleton by way of connective tissues known as tendons. This attachment enables the muscles to extend and contract. The skeleton also produces red and white blood cells. Red blood cells, which are used to transport oxygen throughout the bloodstream, are created in the bone marrow. White blood cells, which the body uses to fight off bacterial and viral infections, are also created inside of the bone marrow, explains PT Direct.
