Oxygen-poor blood is received by right atrium which pumps it to the right ventricle that takes it to the lungs. When blood is oxygenated, it is received by the left atrium which pumps it to the left ventricle to be circulated to the body.

What is the placental mammal's structure of the heart?
All mammals (monotremes, marsupials, and placental mammals) have the same heart structure: a four chambered heart. The four chambers are the left atrium, the left ventricle, the right atrium, and the right ventricle. The right atrium receives deoxygenated blood from the veins. It pumps it into the right ventricle. The right ventricle pumps it into the pulmonary arteries, which go to the lungs. The lungs have received oxygen and give it to the blood coming through. The now oxygenated blood flows back to the heart by pulmonary veins, and is received by the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle pumps the blood to all of the body through arteries.
Chamber of heart that contains oxygenated blood?
As veins flow TOWARDS the heart, the PULMONARY VEINS are the only veins that carry oxygenated blood from the lungs to the LEFT ATRIUM.
