In the heart's blood flow, where does blood go after passing through the right atrium?

• A. Left Atrium
• B. Right Ventricle
• C. Pulmonary Veins
• D. Aorta

Answer: (B)

After blood passes through the right atrium, it enters the right ventricle. This is the next step in the heart's blood flow process, which is critical for pulmonary circulation. The right ventricle is responsible for pumping deoxygenated blood into the pulmonary arteries, which then carry it to the lungs for oxygenation. This sequence is essential for ensuring that the blood receives the oxygen it needs to supply the body effectively. The other options might represent different parts of the circulatory system, but they do not follow directly after the right atrium. For example, the left atrium receives oxygenated blood from the pulmonary veins, while the aorta carries oxygenated blood away from the heart to the systemic circulation, functioning after the left ventricle. The pulmonary veins, on the other hand, specifically return oxygenated blood to the left atrium. Thus, the right ventricle is rightly identified as the immediate destination for blood flowing from the right atrium.
