How many chambers does the heart have?

The heart has four chambers, which consist of two upper chambers known as the atria and two lower chambers called the ventricles. This anatomical structure is crucial for the heart's function, as it allows for the separation of oxygenated and deoxygenated blood. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which then sends it to the lungs for oxygenation. Conversely, the left atrium receives oxygenated blood from the lungs and transfers it to the left ventricle, which pumps it out to the rest of the body. Understanding this chamber system is essential for comprehending the circulatory process and the role of the heart in maintaining adequate blood flow and oxygen distribution throughout the body.
