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. What is the function of the hydraulic filter of the arterial system (composed of the elastic arteries and high-resistance arterioles) Convert the cardiac output flow to steady flow.
