Poiseuille determined the relationship between the resistance in a vessel to several variables. Which statement is TRUE about these relationships?
A. Resistance is proportional to the radius of the vessel raised to the 4th power, the viscosity of the fluid in the vessel, and the length of the vessel.
B. Resistance is proportional to the radius of the vessel raised to the 4th power, the length of the vessel, and is inversely proportional to the viscosity of the fluid in the vessel.
C. Resistance is proportional to the length of the vessel, the viscosity of the fluid in the vessel, and is inversely proportional to the radius of the vessel raised to the 4th power.
D. Resistance is proportional to the radius of the vessel raised to the 4th power, the viscosity of the fluid in the vessel, and is inversely proportional to the length of the vessel.
Answer: C. Resistance is proportional to the length of the vessel, the viscosity of the fluid in the vessel, and is inversely proportional to the radius of the vessel raised to the 4th power.
