The muscular system is made up of… Muscles and tendons
How many muscles do we have? We have about 650 muscles in our body. Our muscles make up half of our body weight.
Our muscles are important because they… Hold our organs in place Hold our bones together so that I can move Help me chew my food Open and close my eyelids Pump my blood Allow me to run and play Help me to smile!
7 Functions a. Produce movement b. Maintain posture and body position c. Support soft tissue d. Guard entrance and exits e. Maintain body temperature
Did you know????? It takes more muscles to frown than to smile?
Why do we need tendons? Tendons attach my muscles to my bone helping my body move. Feel your tendon right above your heel in the back of your leg. This is the thickest tendon in your body.
