Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
Does dehydration increase peripheral resistance?
yes
What causes peripheral resistance?
Peripheral resistance is the force against blood flow. In most cases, an increase in peripheral resistance would be caused by an increase in vasoconstriction, which would decrease blood flow. Other factors can influence vasoconstriction, such as circulating angiotensin II levels, cortisol levels, drugs such as cocaine and other adrenergic agonists, blood volume, atherosclerosis, emboli, renal diseases and increased intra-cranial pressure. An increase in blood pressure will also be caused by vasoconstriction and the mentioned factors.
Would vasoconstriction decrease peripheral resistance?
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
How does viscosity affect peripheral resistance?
If you increase the total peripheral resistance then the arterial blood pressure will increase.
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 are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
Will increasing the conductor thickness increase resistance?
No. A thicker conductor will lower resistance.
Would increasing the resistance increase electric current?
no
What will always increase voltage?
increasing resistance and keeping current constant
How does an open parachute increase the air resistance of a falling?
by increasing surface area
What actions will always increase voltage?
increasing resistance and keeping current constant
