Answer:
The skeletal system has many functions. Besides giving us our human shape and features, it:
Allows movement: Your skeleton supports your body weight to help you stand and move. Joints, connective tissue and muscles work together to make your body parts mobile.
Produces blood cells: Bones contain bone marrow. Red and white blood cells are produced in the bone marrow.
Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
Stores minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.
