what is your heart?

Your entire system gets blood pumps from your heart. your heart  is the most important organ in your body. did you know that your heart beats more than 10000 times a day. your heart is the leader of your organs and keeps the blood for your body. your heart carries about 2.5000 a day.

Your veins carries oxygenated blood and your arteries carries deoxygenated blood. Your heart can move on its own were as all of your other organs need help from your heart. the blood cells starts in the right atrium and then travel through the left atrium. the reason that the circulatory system is called that is because the system moves in a circle.
