Terms in this set (62) Define blood flow. amount of blood flowing through a tissue given time (generally mL/min) Define velocity. distance traveled by blood per unit time (generally cm/min) True or false: velocity cannot change if flow does not change. False, velocity can change even if flow is consistent. Define perfusion. Key Points. 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. Blood …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).Eggplant is high in fiber but low in calories so it’s great to cook with.
