are separated from each other by the interventricular septum.

Detailed explanation-1: -The right atrium, therefore, acts as a reservoir to collect deoxygenated blood. From here, blood flows through the tricuspid valve to fill the right ventricle, which is the main pumping chamber of the right heart.
Detailed explanation-2: -You can think of both atria (the plural form of “atrium”) as reservoirs. While your right atrium holds oxygen-poor blood, your left atrium holds oxygen-rich blood. Your left atrium then sends this blood through your mitral valve and into your left ventricle.
Detailed explanation-3: -The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.
Detailed explanation-4: -The atria perform three different functions during the various phases of the cardiac cycle, i.e. serving as reservoir during systole, passive conduit during early diastole, and booster function during late diastole.
