How does blood viscosity affect blood flow?
Peripheral resistance
What three variables affect peripheral resistance to blood flow?
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
What are the main factors that contribute to total peripheral resistance?
Total peripheral resistance is mainly influenced by the diameter of the blood vessels, vessel length, blood viscosity, and the compliance of the vessel walls. Vasoconstriction and vasodilation also play a significant role in regulating total peripheral resistance. Additionally, factors such as arterial blood pressure and neural and hormonal control can impact total peripheral resistance.
What are factors that affect viscosity and flow?
Pressure and temperature are the two factors that affect flow and viscosity. Viscosity refers to the resistance of a liquid to the shear forces.
What are the factors affecting peripheral resistance which influence BP?
There are three factors that increase peripheral resistance. These factors include autonomic activity, pharmacologic agents, and blood viscosity. Each factor increases the constriction of arteries, which in turn causes peripheral resistance.
How will blood peripheral resistance change as a result of increased hematocrit?
An increased hematocrit indicates a higher ratio of RBC's in the blood. Any increase in cellular elements, whether WBC's, RBC's or platelets, will act to essentially mechanically "thicken" the blood viscosity, sort of like using a heavier grade oil in your car. Increased blood viscosity will increase peripheral resistance, as it becomes harder for the heart to circulate the thicker blood, especially in the capillaries.
How does viscocity affect inertia?
Viscosity is the measure of a fluid's resistance to flow. Higher viscosity fluids have more resistance to motion, which can impact their inertia. In high viscosity fluids, such as honey, the resistance to flow increases the inertia of the substance, making it harder to change its state of motion.
What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
What is the explanation for the term total peripheral resistance?
Total peripheral resistance is the sum of the resistance of all peripheral vasculature in the systemic circulation.
The resistance of a liquid to following is its?
the resistance of liquid to following is its viscosity.
