What are the chambers of the heart, and describe the blood flow through the heart?

The right atrium, right ventricle, left atrium and left ventricle Deoxygenated blood enters the hearts right atrium via the superior and inferior vena cava, then is pumped to the right ventricle (through the tricuspid valve), then is pumped to the lungs to become oxygenated via the pulmonary artery. The oxygenated blood is then returned to the hearts left atrium via the pulmonary vein, this is then pumped to the left ventricle (through the bicuspid valve) before then existing the heart via the aorta
