You may have already heard but we recently finished our body systems unit and model building project, but I just want to get into the specifics of a single body system. I want to talk about the muscular system. Did you know that to take one step you're using just over 200 muscles? That just makes napping not seem to bad after all.
In your body you have three types of muscles. The smooth muscle, the cardiac muscle, and the skeletal muscle. The skeletal muscle is a muscle attached to a bone, a cardiac muscle can only be found in the heart, and the smooth muscle is only found in organs. Something I should mention is if you are dedicated to getting strong and you work really hard at it just know that it takes half as long to gain muscle than it does to lose it. That is not an excuse to sit on the couch all day.
Muscles are very important in everyday life and are necessary to survival. They are really important because they help you move, help your heart beat, and help your other organs function. I chose this topic because I wanted to address how cool and interesting muscles are. Trust there is so much more to learn than I have just told you and I encourage you to learn more.
