All of your blood goes through your large veins. Your heart is in the center of your chest which contains a lot of blood so it can work. There is something green in your body and that is called vein, your vein carries all of your blood back to your heart. If you ever wonder what the thing is called that takes the blood away from your heart it is called your Arteries which the largest artery in our bodies is called Aorta. Your blood sends chemical messages.

Your bloods first loop travles from your heart to your lungs after it travels through your lungs it goes back to your heart. The second loop that the blood makes is that the blood goes through out the whole body then it goes back to your heart again. The Valves prevent from our blood flowing backward.
