According to Poiseuille's law,

A) blood flow is not related to resistance.
B) pH of the blood influences flow.
C) viscosity of the blood is not related to flow.
D) if resistance increases, flow increases.
E) if resistance increases, flow decreases.

Poiseuille's Law

A principle in fluid dynamics that describes the flow of a fluid through a cylindrical vessel, relating the volume flow rate to the vessel's radius, length, and fluid viscosity.

Viscosity

A measure of a fluid's resistance to flow, related to its thickness or stickiness.

Resistance

The ability of an organism to prevent infection or disease despite exposure to a pathogen; or in physics, the opposition to the flow of electric current.
