ATo maintain porosity
BTo maintain perfusion
CTo maintain pressure
DTo maintain position
Answer & Solution
Correct answer: C. To maintain pressure
1. Lumen size affects the pressure carried.
2. A narrower channel holds pressure up.
3. Arteries have smaller lumens than veins, which helps maintain the pressure of blood moving through.
4. So the answer is to maintain pressure.
