WebRight ventricular contraction causes blood to go into the pulmonary circulation, which is not measured with blood pressure testing. The viscosity of blood does not impact the pressure that is exerted on the wall of a blood vessel. Venous pressure is not typically measured, as it is much lower than arterial pressure and is relatively unaffected ... Web8 aug. 2024 · As the diameter of the blood vessels decreases, the velocity of blood flow also diminishes. Estimates are that about 10% to 15% of the total blood volume is contained in the arterial system. This feature of high systemic pressure and low volume is typical of the arterial system.
