What type of blood vessels deliver low-oxygen blood to veins (the smallest of the blood vessels)?

Understand the Problem

The question asks what type of blood vessels deliver low-oxygen blood to veins, which are described as the smallest of the blood vessels. We must identify the correct blood vessel type from the given options.

More Information

Capillaries are the smallest blood vessels that connect arteries to veins. They deliver low-oxygen blood to venules, which are the smallest veins.

Tips

It's easy to confuse the roles of arteries and veins. Remember that arteries carry blood away from the heart, while veins carry blood back to the heart.
