The Heart is a strong muscular pump which gives us blood circulation through our body. The size of an adult heart is about 13 cm (5") in length. The deoxygenated blood from our body will go into the right atrium, and then the right ventricle will pump the blood to our lung. Vice versa, the oxygenated blood from the lung goes into the left atrium, and then the left ventricle will pump the oxygenated blood back to our body through the aorta & branch arteries.
