What are the functions of the skeletal system?
The skeletal system has several jobs, some of which are easier to see and feel than others. But they’re all important to your body and health. Your skeletal system’s major functions include: Giving your body shape: Your skeleton supports the weight of your body. It’s also the anchor for all the tissue that connects to it. Helping you move: Your joints, connective tissue and muscles all work together to push and pull parts of your body every time you move. Protecting your organs: The human skeleton is like a built-in suit of armor for organs throughout your body. Your skull protects your brain, your ribs shield your heart and lungs, and the vertebrae in your spine keep your spinal cord safe. Creating new blood cells: Bone marrow at the center of some of your bones produces new red blood cells and white blood cells your body needs to stay healthy. Storing minerals: Your bones hold your body’s supply of important minerals like calcium and vitamin D.
What are the main parts of the skeletal system?

It does contain all your bones, but your skeletal system has lots of other tissue, too. Your skeletal system is made of your: Bones: Bones are your body’s main form of structural support. Adults have between 206 and 213 bones in their bodies. Muscles: Muscles are made of tightly woven, stretchy fibers. You have more than 600 muscles in your body that help you do everything from walking, running and jumping to breathing and digesting food. Cartilage: Cartilage is strong, flexible tissue that acts like a shock absorber in joints throughout your body. Ligaments: Ligaments are bands of tissue that connect bones to other bones. Tendons: Tendons are cords that connect muscles to bone. Joints: A joint is any place two bones meet. It contains some of (or all) the pieces listed above. Advertisement
