the right atrium receives blood from which three vessels?
pulmonary trunk
superior vena cava
inferior vena cava
coronary sinus
aorta

Explanation:

The right atrium is a chamber of the heart. The superior vena cava brings de - oxygenated blood from the upper body to the right atrium. The inferior vena cava brings de - oxygenated blood from the lower body to the right atrium. The coronary sinus drains de - oxygenated blood from the heart muscle itself into the right atrium. The pulmonary trunk takes blood from the right ventricle to the lungs (not to the right atrium). The aorta takes blood from the left ventricle to the body (not to the right atrium).

Answer:

Superior Vena Cava, Inferior Vena Cava, Coronary sinus
