What are the four chambers of the heart?
The four chambers of the heart are the left and right atria, and the left and right ventricles. The right atrium and right ventricle receive deoxygenated blood from the body and pump it to the lungs to be oxygenated. The left atrium and left ventricle receive oxygenated blood from the lungs and pump it out to the rest of the body. Working together, these four chambers allow the heart to efficiently pump blood throughout the body to deliver oxygen and nutrients to the tissues.
