The Muscular System!!!
The muscular system makes up nearly half the weight of the human body, this is why when we train we sometimes put on weight instead of losing it. We put on muscle weight. The muscles provide the forces that enable the body to move. Muscles stretch across joints to link one bone with another and work in groups to respond to nerve impulses. Muscles need OXYGEN and FOOD to function properly. The muscles also help you moove.
