Inversely proportional to blood flow : F = delta P / R. Peripheral resistance changes based on: 1. Blood viscosity. (thickness) : RBC counts and proteins. The thicker the blood the more resistance and vise versa. 2. Blood vessel length - the longer the blood vessel, the more resistance. 3. 1. blood flows if a pressure gradient (deltaP) is present. 2. blood flows from areas of higher pressure to areas of lower pressure. 3. blood flow is opposed by the resistance (R) of the system. 4. three factors affect resistance: radius of the blood vessels, length of the blood vessels, and viscosity of the blood. Flow is the movement of a liquid or gas over time. Flow can be calculated by multiplying velocity, the distance moved by an object over time, with cross-sectional area. Within the circulatory system, velocity can be altered by changes in blood pressure, vessel resistance, and blood viscosity.

The reason for these differences in blood flow velocity is wall stress (a type of shear stress). When a fluid, in this case, blood, flows through a pipe, friction exists between the fluid and the wall of the tube. This friction decreases the velocity of the blood closest to the wall (hence the shorter lines on the diagram closer to the tube wall).Study with Quizlet and memorize flashcards containing terms like OBJ 1: Be able to differentiate between flow and velocity in terms of units and concept., OBJ 2: Understand the relationship between pressure, flow, and resistance in the vasculature., OBJ 3: Explain how Poiseuille's Law influences resistance to flow. …1st step in blood flow of the heart.
