Muscular System

Function: The 650 muscles in the body not only support movement controlling walking, talking, sitting, standing, eating and other daily functions that we consciously perform but also help to maintain posture and circulate blood and other substances throughout the body, among other functions.

As you tun, the muscles in your legs help with the extension and flexion of you hamstrings and quadriceps. Your muscular system and skeletal system work together to keep the form of your body.
