How Does Your Heart Work?

What is a Heart? Your heart is a muscular organ that pumps blood to your body. The human heart is an
organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to

the tissues and removing carbon dioxide and other wastes. Your heart is at the centre of your circulatory
system.

The heart has four chambers: right atrium, left atrium, right ventricle, left ventricle. Your right atrium and
right ventricle receives blood that’s low in oxygen from  your whole body and sends it to your lungs
through the Pulmonary Artery. The lungs fill blood with oxygen that your left atrium receives then flows

through the left ventricle through the Aortic Artery.

Your veins carry blood to the heart and your arteries carry blood away from the heart. Your rib cage protect

your heart from danger and your heart is about the size of your fist and it doesn’t take  a rest.

It can beat more than 100,000 times in one day pumping about 2000 gallons of blood through your body.
There is about 60,000 miles of vessels in your circulatory system and it always keep them full. It have four
valves that open and close that control the blood through your heart. The Bicuspid, Pulmonary, Mitral and
Aortic valves.

Our heart is a important organ to our body. There’s a lot of interesting information's that you will know
about your heart. Take care of your heart if you want a long and beautiful life.
