How many chambers does the human heart have?

Two
Three
Four
Five

The correct answer is: Four

The human heart has four chambers, which consist of two atria and two ventricles. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae and pumps it into the right ventricle. The right ventricle then sends the blood to the lungs for oxygenation through the pulmonary arteries. Meanwhile, the left atrium receives oxygenated blood from the lungs via the pulmonary veins and passes it to the left ventricle. The left ventricle is the strongest chamber, which pumps this oxygen-rich blood out to the rest of the body through the aorta. This chamber arrangement is crucial for the separation of oxygenated and deoxygenated blood, ensuring efficient circulatory function and sufficient oxygen delivery to meet the body's needs. Understanding the four chambers is fundamental in studying cardiovascular health and related medical conditions.
