What Affects Resistance Of Blood Flow? There are three primary factors that determine the resistance to blood flow within a single vessel: vessel diameter (or radius), vessel length, and viscosity of the blood. Of these three factors, the most important quantitatively and physiologically is vessel diameter. What could cause an increase in the resistance of
Which Of The Following Would Cause A Decrease In Total Peripheral Resistance? Vasodilation of arterioles in the skeletal and heart muscles and skin causes a decrease in total peripheral resistance to blood flow. This decrease is partially offset by vasoconstriction of arterioles in other organs. Which of the following will decrease total peripheral resistance to
What Is The Relationship Between Pressure And Resistance? In the arterial system, as resistance increases, blood pressure increases and flow decreases. In the venous system, constriction increases blood pressure as it does in arteries; the increasing pressure helps to return blood to the heart. What is the relationship between pressure flow and resistance be specific?
