Question 2

Which type of blood vessels contain valves and what is their function?

Accepted Answer

Veins contain valves to prevent blood from flowing backward. This is necessary because the venous vessels are a low- pressure system and the blood must sometimes flow against gravity, particularly in the limbs.
