All you want to know about Heart chamber

Heart chamber is a general term used to refer to any of the four chambers of the mammalian heart (an organ):

Right atrium: receives oxygen-depleted blood from the body via the superior vena cava and the inferior vena cava and pumps it through the tricuspid valve into the right ventricle.
Right ventricle: receives oxygen-depleted blood from the right atrium and pumps it through the pulmonary valve into the lungs via the pulmonary artery.
Left atrium: receives oxygen-rich blood from the lungs via the pulmonary veins and pumps it through the mitral valve into the left ventricle.
Left ventricle: receives oxygen-rich blood from the left atrium and pumps it through the aortic valve to the entire body via the aorta, including to the heart muscle itself through the coronary arteries.
