Bones

All vertebrates have internal skeletons. The human skeleton has over 200 bones and this hard, tough structure protects and supports the rest of the body. For example, the ribs protect the heart and lungs.

The bones vary in shape and size depending on their function. The smallest bones are inside the ear and the largest is the femur (top leg bone). Male skeletons are different to female skeletons. For example, the female pelvis is a different shape to allow a baby to be born.

Bones are not solid. The outer part of the bone is compact bone and has nerves and blood vessels and in the centre there is soft bone marrow, which is where new blood cells are made. Calcium is needed to make strong bones.

Bones are joined to other bones at joints by strong tissue called ligaments.
