What is the purpose of the muscled system?

Answer 1

Muscles allow the body to move. There is your basic answer.

To give more information, you have three types of muscles. They are skeletal, smooth, and cardiac muscles. Your skeletal muscles are attached to your skeletal system as the name implies. The smooth muscles are all muscles that aren't skeletal muscles or cardiac muscles such as your diaphragm, which controls breathing, and stomach, which causes the stomach's contraction and expansion. Your cardiac muscles control the heart's beat.

So as far as the purpose of the muscles system, is to keep you alive. Without it, you could not move, digest food, or circulate blood throughout your body.
