The cardiovascular system is what allows your body to circulate blood, fight germs, and get rid of dead cells. The cardiovascular system is also known as the circulatory system which allows blood to flow through your body. In the circulatory system there are three different types of cells that each serve a different purpose. Red blood cells carry oxygen through the body, white blood cells fight of unknown bacterias, and clotting platelets that fill in scrapes, cuts, and other damaged parts of the body. All of these cells travel through the body with the help of three main organs. The Arteries pump blood away from the heart, veins bring the blood back to the heart,and capilaries which is where the arteries and veins connect to give out oxygen. If you stretch out your arteries, veins, and capillaries they could go around the world a little more than two full times. I personally thought that this article was interesting but also imformative. Here is a link to my source.
