Which of the Following Would Increase the Rate of Blood

Question

Which of the following would increase the rate of blood flow through a blood vessel?
A) decreased radius of the vessel
B) increased pressure of the blood entering the vessel
C) constriction of the blood vessel
D) increased viscosity of the blood
E) increased length of the vessel

Accepted Answer

Increased pressure of the blood entering the vessel increases the rate of blood flow through a blood vessel according to the principle of fluid dynamics, where flow rate is directly proportional to the pressure difference across the vessel.
