THE HUMAN BODY SYSTEM Justin Glover THE SKELETAL SYSTEM The skeletal system is made up of many bones. The main bone is your spine. It allows you to bind over and pick up something. There are also the hand bone the foot bone and more. All the bones help you do stuff like walking and they also support your body. The longest bone in your body is the femur. Did you know that your bones are filled with a fatty substance called bone marrow. In the bone marrow the red and white blood cells are manufactured then released into the blood stream. And over half of the bones in your body are hand and feet bones and that your bones stop growing at age 16 for girls and age18 for boys.
