The Muscles
Your muscles are part of the muscular system. Your muscles
work together with the bones in your skeleton to allow you to move.
Your muscles give you strength and power!
One kind of muscle is skeletal muscle. These muscles make
movements that you make intentionally, or on purpose. For example, if
you decide to stand up, your skeletal muscles do the work. Skeletal
muscles work in pairs. When one muscle contracts, or squeezes, the
other one relaxes. This moves your bones. These muscles are
connected to your bones by tendons.
Another kind of muscle is smooth muscle. Smooth muscles do
work inside your body that you don’t have to think about. For example,
smooth muscles in your stomach push food through your digestive
system. You don’t have to do anything to get them to do their jobs.
They take care of it for you!
Another kind of muscle is cardiac muscle. The word cardiac refers
to the heart. Your heart is actually a muscle! This muscle pumps blood
through your body. It is the hardest-working muscle in your body.
Did you know that you have about 650 different muscles in your
body? Your muscles are equal to about half of your body weight! Your
muscles need to be active to stay healthy and strong. Give your
muscles the energy they need by eating healthy foods each day!
