The Immune System And Muscles
Our bodies face many problems every day. One problem our bodies must face is the problem of getting blood back to the heart. Because we stand upright, the blood must fight gravity to get back to the heart. This also means that the immune cells who travel with the blood must get back to the heart, in order to continue the patrol of the body. The muscular system is what helps this. When the muscles in your body contract, the squeeze the blood vessels,causing the blood to flow faster for a moment, long enough to get past the next valve, which will prevent the blood from flowing down again. every time your muscles contract, it helps in getting your blood and immune cells back to the heart, so they can continue thier vital journey.
