Question

1. when blood pressure increases, blood flow __. when resistance increases, blood flow __. a. slows down, speeds up b. stops, reverses c. speeds up, slows down d. reaches the extremities, moves into veins

Explanation:

Blood flow is directly proportional to blood pressure and inversely proportional to resistance. Higher blood pressure means more force pushing the blood, so flow speeds up. Higher resistance impedes the flow, so it slows down.

Answer:

c. Speeds up, slows down
