How does obesity change blood vessel length?
blood vessels lengthen by miles
Why would blood vessel radius have a larger effect on the body than vessel length?
A blood vessel's radius has a larger effect on the body than the vessels length because more blood can flow through a larger blood vessel. A change in the radius will have more of a affect.
Why is blood vessel radius more likely to change than blood vessel length?
Radius. Length only changes with weight loss, gain or while one is growing. (from infancy to adult)
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.
What are the main factors that contribute to total peripheral resistance?
Blood vessel diameter,blood viscosity and total vessel length
Factors that affect vascular resistance?
I I think it is 1. size of the blood vessel lumen 2. blood viscosity 3. total blood vessel length
What Two major factors affecting blood flow rates?
They include the radius of the blood vessel, the length of the system, and the viscosity of the blood.
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 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.
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 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.
Which of the following is NOT an important source of resistance to blood flow?
Total Blood Volume "There are three important sources of resistance: blood viscosity, vessel length, and vessel diameter." - Anatomy & Physiology 4E Marieb/Hoehn page 612.
