Question

if the capillaries are blocked by sickle cell anemia cells, what will happen to the blood flow to the tissues? it will decrease the blood flow. it will increase blood flow. it will stay the same.

Explanation:

Capillaries are tiny blood vessels that supply blood to tissues. If they are blocked by sickle - shaped cells (in sickle cell anemia), the passage for blood to flow through to the tissues is restricted. When a passage is blocked, the amount of blood that can flow through it to the tissues will be less. So the blood flow to the tissues will decrease.

Answer:

A. It will decrease the blood flow.
