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. In-creased blood pressure decreases blood flow because resistance is increased. Blood volume, not composition, plays a role in blood flow. |
