-6
6
-15
23

question 11
0.8 pts
after xors blood vessels dilate, the resistance to blood flow decreases to r = 0.5 mmhg\cdotmin/ml while the pressure difference p1 - p2 falls to 15 mmhg. what is the new rate of blood flow (f) in ml/min?
-5
30
-10
5

Explanation:

State the governing equation

Using the Ohms Law of Blood Flow and Hemodynamics knowledge points

$$ F = \frac{\Delta P}{R} = \frac{P_1 - P_2}{R} $$
