steel girders and reinforced concrete of the body; form internal framework that supports and anchors all soft organs; bones in legs act as pillars; rib cage support thoracic wall
protect soft body organs, ex- skull protects brain; vertebrae surround spinal chord; rib cage helps protect vital organs of the thorax
one vital part of the movement process together with muscles and tendons; bones are whats being pulled by muscles and tendons are what connects the two; if there were no muscles, we would fall to the ground; if there were no bones; we would just lay there and contract
