What three variables affect peripheral resistance to blood flow?
Wiki User
∙ 12y ago
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.

∙ 13y agoThe electrical resistance of an object depends on:
- Its length
- Its cross-sectional area
- What material it is made of
- It also depends slightly on the temperature.

Decreased peripheral resistance to blood flow?
Anemia
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 factors influence resistance to blood flow?
blood volume
What is a pencil cell?
A cell from the peripheral blood smear that has a pencil shape, i.e. long and pointy, under the microscope.
How does blood viscosity affect blood flow?
Peripheral resistance
How does viscosity affect peripheral resistance?
If you increase the total peripheral resistance then the arterial blood pressure will increase.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
What is main site of peripheral resistance?
arterioles offer maximum peripheral resistance .Skin and skeletal muscle blood vessels represent most imp. site of peripheral resistance.
What is blood flow directly proportional to?
Peripheral resistance
Decreased peripheral resistance to blood flow?
Anemia
A resistance to blood flow due to friction between blood and blood vessel walls is called what?
it is called peripheral resistance.
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
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.
4 factors that affect blood pressure?
There are four factors that affect the blood pressure. The things that can affect blood pressure are stress, genetics, a high salt intake, and exercise.
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
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.
