1 Your Amazing Muscular System By Samantha and Niki
2 Your Wonderful Muscles The Muscular System is a very important part of the human body. Some muscles help by pumping blood to the heart, some help you digest, and others help you move. If you didn’t have muscles your blood wouldn’t get pumped to the heart, you couldn’t digest, and you couldn’t move.
3 Your Miraculous Muscular System Did you know that there are three different types of muscles. Their names are cardiac, smooth, and skeletal. The cardiac and smooth muscles are involuntary. Involuntary muscles work without you thinking about it. The skeletal muscles are voluntary. Voluntary muscles let you control them.
4 A Little Bit More About Your Muscles Most of your skeletal muscles are attached to bones. Your muscles help you move by pulling on the bones and making them move. Not all muscles are attached to your bones. Some other types of muscles like cardiac and smooth muscles aren’t hooked to bones. The cardiac muscle helps by pumping blood to the heart from other parts of the body. The smooth muscle helps by tightening up and relaxing to let food pass through your small and large intestine.
