The Muscular System
_________________________________________
muscular system Tissues that move parts of the body and control the organs
Skeletal muscles are voluntary.
They work in pairs to move bones. As one muscle contracts, the other lengthens.
Smooth and cardiac muscles are involuntary.
Smooth muscles are found in your body’s organs and blood vessels.
The heart has its own special type of involuntary muscle called the cardiac muscle.
The muscular system provides the power and flexibility you need to move.

12. Caring for Your Bones and Muscles
Tips for Caring for Your Bones and Muscles
Do flexibility exercises.
________________________________________________________________
Choose physical activities that build cardiovascular strength.
Good posture is not stiff posture. Sit and stand in a correct but relaxed way. Your lower back should be slightly curved. If you use a backpack, try not to overload it.
When you lift heavy objects, make your legs do most of the work. See a doctor if you get hurt.
Foods high in protein can help build muscle.
Foods high in Vitamin D, calcium, and other minerals help your bones grow and become stronger.

When you lift heavy objects, keep your back straight and bend your knees.
