Pressure, flow and velocity of blood

Total blood flow (L/min) is equal in all areas of the vascular circuit (arterial, capillary, venous) yet the velocity of flow (mm/s) is inversely proportional to the total cross sectional area of each region. This generates flow velocity that is very high in the aorta and large veins, yet very much slower in the capillaries which have an enormous total cross sectional area. This is, of course, adaptive to the need for capillary exchange in these very short vessels.
