Vessels that contain valves to prevent backflow of blood?

A
Veins

B
Arteries

C
Capillaries

D
Atrium
Solution
- Unlike arteries, veins contain valves that ensure blood flows in only one direction.
- Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.
- Valves also help blood travel back to the heart against the force of gravity.
Thus, the correct answer is option A.

- Capillaries are tiny vessels that branch out from arteries to form networks around body cells.
- In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation.
Therefore, Option B is correct.

A
Arteries

B
