The skeletal system keeps the body upright and allows for movement. Key bones include the spine, ribs, skull, and pelvis. The spine protects the spinal cord and keeps us upright. The ribs protect internal organs like the heart and lungs. The skull protects the brain. The pelvis protects the bladder and forms the hips. Exercise and a calcium-rich diet are important for keeping bones healthy as we age.
