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.
How does viscosity affect peripheral resistance?
If you increase the total peripheral resistance then the arterial blood pressure will increase.
Will increasing the conductor thickness increase resistance?
No. A thicker conductor will lower 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.
Would increasing the resistance increase electric current?
no
What will always increase voltage?
increasing resistance and keeping current constant
How does increasing the wire gauge from awg 22 to awg 26 generally effect resistance?
Resistance will increase.
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
How does an open parachute increase the air resistance of a falling skydiver?
by increasing surface area
