What does the heart do for the heart?

Answer:
No you don't have a heart inside your heart. The heart is made up of four chambers though. This is a short explanation about the heart.
The heart is a very important muscle that you can't live without it. It pumps blood through your body.

The heart is made up of 4 different parts that are called the chambers. The chambers are called Left atrium, Right atrium, Left ventricle and Right ventricle. The left atrium receives blood from the pulmonary-vein, and pumps it into the left-ventricle. The right atrium receives de-oxygenated blood from the superior and the inferior venae cavae and the coronary-sinus. The left ventricle receives oxygenated blood from the left-atrium via the mitral-valve, and pumps it into the aorta.
