How many atria are present in the human heart?

One
Two
Three
Four

The correct answer is: Two

The human heart contains two atria, which are the upper chambers of the heart. These atria play a critical role in the cardiac cycle by receiving blood that comes into the heart. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae, while the left atrium receives oxygenated blood from the lungs through the pulmonary veins. This structure is essential for the heart's function, as it allows for an efficient flow of blood to the ventricles, which then pump it to the lungs and the rest of the body. Understanding the function and anatomy of the atria is fundamental for anyone studying esthetics, as it connects to the overall knowledge of human biology and the circulatory system.
