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).
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 …

Capillaries, Alternative routes of blood supply are called … Blood flow velocity is controlled mainly by the diameter of the blood vessel. Since capillaries are the smallest blood vessels, they also have the slowest blood flow velocity. This also plays a vital part in the transport of nutrients since the slow velocity allows for a complete transfer of nutrients and oxygen in the capillaries. As shown in Figure 20.2.1, the difference between the systolic pressure and the diastolic pressure is the pulse pressure. For example, an individual with a systolic blood pressure (BP) of 120 mm Hg and a diastolic BP of 80 mm Hg would have a pulse pressure of 40 mmHg. Pulse pressure = systolic BP – diastolic BP.20.2. Find step-by-step Calculus solutions and your answer to the following textbook question: The velocity v of blood that flows in a blood vessel with radius R and length l at a distance r from the central axis is $$ v (r)=P/4ηI (R^2-r^2) $$ where P is the pressure difference between the ends of the vessel and η is the viscosity of … Velocity of blood flow is inverse to the total cross sectional area of the blood vessels.

In order to maintain the constant blood flow, if the cross-cross-sectional area of the vascular tree increases, the velocity of blood flow decreases. Also, if the cross-cross-sectional area of the vascular tree decreases, the velocity of blood flow increases. Therefore, the statement in the letter in the letter a is correct. What is blood flow velocity? The rate of blood transported per unit time (cm/sec). What is the relationship between total-cross sectional area and blood flow velocity? It is INVERSE.
