Blood Pressure Gradients

Submitted by Juli Uhl on

The same kind of blood flows through three very long identical blood vessels. Each vessel has the same diameter but different flow rates of blood.  A  scientist measures the pressure of the blood near the beginning and near the end of each blood vessel.

Which blood vessel has the greatest flow rate (L/min) of blood?
a) Blood vessel 1
b) Blood vessel 2
c) Blood vessel 3

Explain why the blood vessel you selected has the greatest flow rate (L/min) of blood.
