Which of the following is NOT an important source of resistance to blood flow?
An important source of resistance to blood flow is not low blood viscosity, as low viscosity would actually decrease resistance. The important sources of resistance to blood flow are vessel diameter, vessel length, and blood viscosity.
What is the affect on blood flow on the radius vessels?
The relationship between blood flow through a vessel and the radius of the vessel can be expressed as BF=1/pi r4 (where pi is equal to 3.14.....). So a change in the radius of a vessel has a large effect on the blood flow through the vessel.
Why would blood vessel radius have a larger effect on the body than vessel length?
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
Resistance to blood flow depends mainly on?
Resistance to blood flow depends mainly on the diameter of blood vessels and the viscosity of blood. Smaller vessel diameter and higher blood viscosity lead to increased resistance, which can affect blood pressure and flow rates.
Explain relationship between the diameter of vessels and the velocity of blood?
As vessel diameter decreases, blood velocity increases due to the principle of conservation of flow rate. This relationship is described by Poiseuille's law, which states that blood flow is directly proportional to the fourth power of vessel radius. Therefore, smaller vessels result in faster blood flow velocities.
Vessel with the fastest blood flow?
Branchial
What is faster blood flow in the center of a large vessel or blood flow along the walls of a blood vessel?
Blood flow in the center of a large vessel is faster because the walls of the blood vessel may have a buildup of cholesterol on them.
What is the effect of increased vessel length on blood flow?
The longer the vessel is the more friction it applies on the passing blood, the less the blood flow is.
Which blood vessel does blood flow with a pulse?
artery
What makes the blood flow inside the tubes or blood vessel?
Contractions and relaxation of heart chambers make the blood flow inside the tubes or blood vessel.
Which blood vessel will allow a force flow of blood?
cappillaries
Which blood vessel will allow a forceful flow of the blood?
cappillaries
Arterioles flow into what blood vessel?
Capillaries
what is a blood clot that shuts off a vessel?
A thrombus may, or may not, block the flow of blood in a vessel.
What is Vasolidation?
increase in the diameter of blood vessel. it increases the blood flow
What are serious but infrquent complications of atherectomy?
blood vessel holes, blood vessel wall tears, or reduced blood flow to the heart
What is blood flow generated by?
The flow of blood times the resistance of the blood vessels.
