Full Answer

There are 200 main skeletal muscles. These are the muscles that do the obvious work of the body, such as the biceps, the quadriceps, the pectorals, the abdominals and the obliques. There are another 100 muscles or so that control the movements of the face, the hands and the feet. There are about 400 more, such as tiny facial muscles, tongue muscles, muscles that move the eyeballs and muscles of the pelvic floor, that are so small and so obscure that only medical specialists ever need to know about them.

    How do skeletal muscles aid the circulatory system?

    A:

    The skeletal muscles, the muscles that power voluntary movements of the body, aid the circulatory system as the primary method by which deoxygenated blood is pushed back to the heart through the veins. Veins have thin walls compared to arteries and are easily compressed as skeletal muscles contract, forcing blood along the vein. Backflow is prevented by the presence of valves within the veins, a feature arteries largely lack.
