E) blood composition.

Question

Quizplus · Accepted Answer

Resistance to flow is generally greater in longer tubes because resistance increases with length but decreases with a wider diameter.Blood flow varies inversely with the viscosity of the fluid.Thick fluids move more slowly and experience greater resistance to flow than thin fluids.Increased blood pressure decreases blood flow because resistance is increased.Blood volume, not composition, plays a role in blood flow.
