According to Poiseuille's law, a small decrease in the diameter of a vessel will
A) dramatically decrease blood flow.
B) slightly decrease blood flow.
C) not affect blood flow.
D) slightly increase blood flow.
E) dramatically increase blood flow.
Poiseuille's Law
describes the flow of a viscous fluid through a long cylindrical pipe, where the flow rate is dependent on the fluid's viscosity, the pressure difference, and the dimensions of the pipe.
Blood Flow
The movement of blood through the circulatory system, delivering oxygen and nutrients to tissues and removing waste products.

Final Answer :
A
Explanation :
Poiseuille's law states that blood flow through a vessel is inversely proportional to the fourth power of the vessel's radius. Therefore, even a small decrease in the diameter (or radius) of a vessel will dramatically decrease blood flow.
