Question

Oxygenated blood reaches heart heart by aorta pulmonary artery pulmonary vein Vena cava

Answer 1

Explanation:

The pulmonary veins carry oxygenated blood from the lungs into the left atrium where it is returned to systemic circulation. The aorta is the largest artery in the body.

The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein.

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Answer 2

The left heart deal with systemic circulation, while the right heart deal with pulmonary circulation. The left side of the heart receives oxygenated blood from the pulmonary vein

and pump it into the aorta, while the right side heart raceives deoxygenated blood from the vena cava and pumps it into the pulmonary vein.

The pulmonary vein and aorta also have valves

connecting them to their respective ventricle.
