How many chambers are there in the heart and which ones?
Four of them, atria (left and right) and ventricles (left and right)
There are four chambers in the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
The right atrium is located in the upper right part of the heart and receives deoxygenated blood from the body through the superior and inferior vena cava. From the right atrium, the blood flows to the right ventricle.
The right ventricle is located in the lower right part of the heart and pumps the deoxygenated blood received from the right atrium to the lungs through the pulmonary artery. The blood picks up oxygen in the lungs and returns to the heart through the pulmonary veins.
The left atrium is located in the upper left part of the heart and receives oxygenated blood from the lungs through the pulmonary veins. From the left atrium, the blood flows to the left ventricle.
The left ventricle is located in the lower left part of the heart and pumps the oxygenated blood received from the left atrium to the rest of the body through the aorta. The left ventricle has thick muscular walls to support its role as the main pumping chamber of the heart.
