The heart is divided into four chambers. The upper chambers are termed atria, and the interatrial septum constitutes the division between them. The lower chambers are termed ventricles, and are divided by the interventricular septum.

Left atrium. The upper right chamber of the heart. The left atrium receives oxygenated blood from the lungs and pumps it down into the left ventricle which delivers it to the body.

Right atrium. The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.

Left ventricle. The left lower chamber of the heart that receives blood from the left atrium and pumps it out under high pressure through the aorta to the body.

Right ventricle. The lower right chamber of the heart that receives deoxygenated blood from the right atrium and pumps it under low pressure into the lungs via the pulmonary artery.

Right and left atrium , right and left ventricle

they receive blood devoid of oxygen and pump it to lungs

and the left side receives blood from the lungs and pumps it to the whole body through the aorta!
