Quick Answer

The human skeleton protects the inner organs, supports the body's frame, stores the body's chemicals and minerals, facilitates blood transportation and formation and makes movement possible. The skeleton is made up of more than 200 connected bones. Skeletons also contain cartilage, which are the thick, rubber-like tissues found in joints.

Full Answer

According to InnerBody, each bone in the human skeleton contains blood vessels and bone marrow made of fat cells, connective tissue cells and nerve cells that help transport blood throughout the body. The skeleton also helps to hold internal organs in place. For example, the human skull keeps the brain stationary, and the chest cavity supports the heart and lungs. The human skeleton not only encases vital organs, but it also protects them from damage.

Human bodies are able to move because skeletal bones contain ligaments and tendons, which perform certain movements when specific muscles contract. The shape and size of each bone affects its potential range of motion. For example, the small bones in a person's hands make it possible to perform precise, detailed activities, such as writing or tying shoelaces. The large bones that make up the legs and arms allow humans to walk, run and lift objects.
