Muscle System – Structure fits Function

 

Do you ever wonder how the heart does all those things fir your body? Do you ever wonder if the shape of you heart changes what it does? If your heart was shaped differently would it still do the same things or would it have different functions?

The heart is a muscle. The function of the heart is to pump blood and circulate it through the body. The structure helps the function because the heart is round so the veins that spread can go at any angle and any part of the body. Another reason is that it’s good that the heart is more at the top of your body than the bottom because it’s probably easier for blood to travel down than up. The heart is small so it is hard for it to be punctured and there are valves on the heart that make it easier to make blood flow through your body.

The heart is helpful to the brain because the brain needs a lot of blood and the heart is very close to the brain.
