Heart chamber

From Wikipedia, the free encyclopedia

Heart chamber is a general term used to refer to any of the four chambers of the Mammalia heart:

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 be delivered throughout the body, including to the heart muscle itself via the coronary arteries.
