WebAug 19, 2024 · When an artery constricts, the flow of blood decreases and the pressure within the vessel rises. Vasoconstriction is a mechanism your body uses to regulate important functions in the body,... WebJan 17, 2024 · The resistance to flow generated by veins, due to their minimal ability to contract and reduce their diameter, means that regulation of blood pressure by veins is minimal in contrast to that of muscular vessels, primarily arterioles. The latter can actively contract, reduce diameter, and increase resistance and pressure.

Blood Flow and Blood Pressure Regulation – Biology

WebIt is known that the resistance to flow through a cylindrical tube or vessel depends on several factors (described by Poiseuille) including: 1) radius, 2) length, 3) viscosity of the fluid (blood), and 4) inherent resistance to flow, as follows: R = 8 L η π r 4 where r = inside radius of the vessel, L = vessel length, and η = blood viscosity. WebVeins are the blood vessels that carry blood back to the heart from the tissues.
