Which statement is correct?
A
All arteries carry oxygenated blood
B
All veins carry oxygenated blood
C
All arteries excerpt pulmonary artery carry oxygenated blood
D
All veins except pulmonary vein carry oxygenated blood
Explanation: 

Detailed explanation-1: -Arteries generally carry oxygenated blood. But pulmonary artery is the artery that transmits deoxygenated blood away from the heart to the organs (like lungs and placenta, respectively) where it gets oxygenated.

Detailed explanation-2: -Arteries are blood vessels that supply oxygen-rich blood to the entire body. They are tube-like vessels. The pulmonary artery is an exception as it carries blood poor in oxygen away from the heart instead of a vein. The pulmonary vein carries oxygen-rich blood to the heart, hence is an exception.

Detailed explanation-3: -Final answer: Except pulmonary artery all arteries carry oxygenated blood.

Detailed explanation-4: -Answer and Explanation: All arteries carry oxygenated blood except the pulmonary trunk and its branches. The pulmonary trunk receives deoxygenated blood from the right ventricle of the heart through the pulmonary valve.

Detailed explanation-5: -Arteries are attached directly to the heart and are in charge of taking oxygenated blood (pure blood) away from the heart to fuel the tissues throughout the body. This is true for all arteries except the pulmonary artery, which carries deoxygenated blood back from the lungs.
