Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Venous blood is carried to the lungs for oxygenation by the.
A
Pulmonary arteries
B
Pulmonary veins
C
Pulmonary arterio-venous shunt
D
Right ventricle
Explanation: 

Detailed explanation-1: -Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk ) leaves your right ventricle at your pulmonary valve.

Detailed explanation-2: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. 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: -The pulmonary arteries are blood vessels that carry systemic venous blood from the right ventricle of the heart to the microcirculation of the lungs. Unlike in other organs where arteries supply oxygenated blood, the blood carried by the pulmonary arteries is deoxygenated, as it is venous blood returning to the heart.

Detailed explanation-4: -Pulmonary arteries carry deoxygenated blood from the heart to the lungs. This is unlike other arteries which carry oxygenated blood. Similarly, oxygenated blood is carried by the pulmonary vein unlike other veins.

Detailed explanation-5: -Your pulmonary arteries carry oxygen-poor blood. Your pulmonary veins carry oxygen-rich blood. They travel in different directions. Your pulmonary arteries carry blood from your heart to your lungs.
