Heart chambers

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Heart beat

Two distinguishable sounds can be heard during the cycle of the beating heart when listened to with a stethoscope. The heart sounds are usually described as a lup-dup sound. These sounds are due to the closing of the valves of the heart. Unusual heart sounds are called murmurs.
