Do veins have valves
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Veins do have valves. These valves are responsible for preventing the backflow of blood and ensuring that it flows in one direction towards the heart. When the muscles surrounding the veins contract, they push the blood forward, and the valves open to allow the blood to pass through. Once the muscles relax, the valves close to prevent the blood from flowing backward. This mechanism helps maintain proper blood circulation in the body.Rate this question:
