Actually our blood is working with the heart, they pretty much go hand and hand. The heart pumps the blood through every part of our body. From the tops of our head to the tips of our toes. It starts off by going through the aorta that’s the large artery coming from the heart. Then it goes to the Capillaries, those are the small arteries connecting the arteries and the veins together. Then the blood travels to the veins sending the blood and oxygen through out our body. So anywhere you get cut you are going to bleed.
