Detailed explanation-4: -In all but one case, veins carry oxygen-poor blood. The exception is the pulmonary veins. They carry oxygen-rich blood from the lungs back to the heart.

Detailed explanation-5: -Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body.
