Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight, while Joints are where two bones meet. They make the skeleton flexible — without them, the movement would be impossible.Bones also protect the body's organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
