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 factors influence resistance to blood flow?
blood volume
A fluid resistance to flow?
A fluid's resistance to flow is called viscosity.
Is the R-value of insulation indicate resistance to heat flow?
yes the R-value does indicate resistance to heat flow
Do insulators have lower resistance than conductors?
On the contrary, insulators have higher resistance than conductors. Resistance refers to resisting a flow of electricity, making it more difficult for electricity to flow. Conductors conduct electricity, they make it easy for electricity to flow. Insulators prevent the flow of electricity.
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
How does blood viscosity affect blood flow?
Peripheral resistance
What is blood flow directly proportional to?
Peripheral resistance
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
A resistance to blood flow due to friction between blood and blood vessel walls is called what?
it is called peripheral resistance.
What is the relationship between peripheral resistance and blood pressure?
Systolic BP is a measure of blood pressure while the heart is pumping; diastolic BP is a measure of blood pressure while the heart is not pumping. BP is the pressure of the blood on the walls of the blood vessels.
What is the principles relating to blood flow and pressure and resistance?
Blood pressure = (Blood flow)(Resistance). This equation is usually found in the following form: MAP = (CO)(R) Where MAP is the mean arterial pressure CO is the cardiac output R is the peripheral resistance
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 decreases blood flow through arterioles?
Vasoconstriction of an arteriole increases resistance and results in decreased flow through that particular arteriole.
What is blood flow resistance?
The resistance of blood flow is what?
What is peripheral blood flow?
Peripheral blood flow refers to blood flow that occurs in the extremities as opposed to blood that flows to the brain, heart, lungs, and vital organs.
How does reactive hyperemia work?
Decreased tissue blood flow due to occlusion will result in metabolic vasodilators accumulating in the extracellular fluid. The arterioles will hence dilate but the occlusion will still prevent normal blood flow. The occlusion is then removed and decreased resistance will increase blood flow. As the vasodilators are washed away, the arterioles constrict, and the blood flow returns to normal.
