Detailed explanation-1: -The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

Detailed explanation-2: -Pulmonary veins: Your pulmonary veins do the opposite job of your pulmonary arteries. They collect oxygen-rich blood and carry it from your lungs to your heart. This blood empties into your heart’s top left chamber (left atrium).

Detailed explanation-3: -The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.

Detailed explanation-4: -Pulmonary veins carry oxygenated blood from lungs to the left atrium where it is returned to the systemic circulation. Veins carry deoxygenated blood from our body towards the heart which further moves to lungs and gets oxygenated, but we have two exceptions in veins and arteries when their functions get altered.
