The Muscular Syestem
By Abdul Adewale
How it Works
How it Affects our Life
Characteristics:Weakness and wasting of shoulder, upper arm and shin muscles. Joint deformities are common, and heart complications can be serious.
Healthy muscles let you move freely and keep your body strong. They help you to enjoy playing sports, dancing, walking the dog, swimming, and other fun activities. And they help you do those other (not so fun) things that you have to do, like making the bed, vacuuming the carpet, or mowing the lawn.
Strong muscles also help to keep your joints in good shape. If the muscles around your knee, for example, get weak, you may be more likely to injure that knee. Strong muscles also help you keep your balance, so you are less likely to slip or fall.
And remember—the activities that make your skeletal muscles strong will also help to keep your heart muscle strong!
