|
carries deoxygenated blood to left atrium
|
Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
Detailed explanation-3: -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.
Detailed explanation-4: -The pulmonary veins carry oxygenated blood from the lungs to the left atrium.
