Question

To tackle this question, let's lay out the basic roles of the heart chambers in the circulatory sequence.
Option a: aorta. The aorta is the main artery that carries blood away from the left ventricle to the systemic circulation, not a receiving chamber. So this choice describes an output vessel, not a receiving chamber.
Option b: right atrium. The right atrium is the first receiving chamber that collects deoxygenated blood from the body via the superior and inferior vena cavae and then passes it to the right ventricle. This aligns with the concept of the initial/first receiving chamber in the flow of blood through the heart.
Option c: lungs. The lungs are organs for gas exchange, not a chamber of the heart. They are where blood is oxygenated, but they are not a cardiac chamber.
Option d: vena cavae. The venae cavae (superior and inferior) are large veins that deliver blood to the right atrium. They are vessels, not a cardiac chamber, so they do not function as the initial receiving chamber.
Option e: left atrium. The left atrium receives oxygenated blood from the lungs via the pulmonary veins, but it is the second receiving chamber in the sequence, after the right atrium, not the first.
Option f: left ventricle. The left ventricle pumps oxygenated blood into the aorta for systemic circulation; it is a main pumping chamber, not the initial receiving chamber.
Option g: right ventricle. The right ventricle pumps blood to the lungs via the pulmonary artery, serving as a sending chamber rather than the initial receiving chamber.
In summary, each option maps to a specific role, either as a receiving chamber, a pumping chamber, or a vessel, but only the right atrium functions as the first receiving chamber in the normal flow of blood through the heart.
