Poiseille's law is often used to calculated the arteriolar blood flow. study the equation for poiseuille's law and determine which has an affect on blood flow.
a) brain tumor
b) blood in urine
c) plaques on arteries
d) resting heart rate of 80 bpm

C

Explanation:

Really interesting question. You need something that will change one of the letters in the formula.

D changes nothing. It is not mentioned in the formula

B the formula does not speak of blood in bad places. So B is not the answer.

A is the same as B. Tumors or any derivative would not not part of blood flow.

C is the answer. Plaque has the effect of reducing the radius of the blood vessel. We are always warned to keep our plaque down because it will raise the blood pressure needed to move blood around.
