Question

Quizplus · Accepted Answer

The function of an atrium is to collect blood and then pump it to the ventricle. Option A is not correct because the atrium doesn't collect all the blood; it only collects blood from a specific set of veins. Option B is incorrect because the ventricle is responsible for pumping blood to the lungs, not the atrium. Option C is incorrect because the atrium doesn't pump blood into the systemic circuit; that role is fulfilled by the ventricle. Option D is incorrect because the atrium doesn't pump blood to the ventricle itself; it just collects it before it's pumped to the ventricle.
