What are the parts of heart?

Here are the four chambers of the heart and their major functions:

- Right atrium - receives deoxygenated blood from the body through the superior and inferior vena cava

- Right ventricle - pumps deoxygenated blood to the lungs through the pulmonary artery

- Left atrium - receives oxygenated blood from the lungs through the pulmonary veins

- Left ventricle - pumps oxygenated blood to the body through the aorta

Other important parts of the heart include:

- Valves - prevent backflow of blood as the heart chambers contract

- Septum - muscular wall that separates the right and left sides of the heart

- Coronary arteries - supply oxygenated blood to the heart muscle

- Coronary veins - drain deoxygenated blood from the heart muscle

- Myocardium - muscular wall of the heart chambers

- Endocardium - thin membrane that lines the inside of the heart chambers
