Muscles are made of tiny fibers in our bodies that can tighten and help us move. They are really important for many body jobs, like walking, standing up straight, pumping blood, and digesting food. For instance, the muscles in our arms and legs let us walk and pick things up, heart muscles keep blood flowing, and smooth muscles help move food in our stomachs. There are more than 600 muscles in our body, and each one is key to keeping us healthy and doing everyday things.
