The skeletal system is composed of 206 bones that provide structure, protect organs, allow movement, and produce blood cells. Bones are living tissues made of cells and composed of minerals and collagen. The skeletal system includes bones in the hands, face, and longest bone being the femur, with the smallest being the stirrup bone in the ear. Joints connect bones to enable the body's 230 movable joints, and giraffes have the same number of neck bones as humans.
