Detailed explanation-1: -The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
Detailed explanation-2: -Right ventricle: Your heart’s bottom right chamber (right ventricle) pumps oxygen-poor blood through your pulmonary valve into your main pulmonary artery.
Detailed explanation-3: -Normally, each pulmonary vein connects directly with your left atrium. In that case, there are four ostia (openings) in your left atrium, one for each of your pulmonary veins. Oxygen-rich blood travels through these openings and into your left atrium.
