What is the medical term meaning constriction of blood vessels?
Vasoconstriction is the normal narrowing of a blood vessel.
What is the root of vasospasm?
The term means a tightening of a blood vessel. Vaso-=vessel + spasm=constriction. The root of the word is vaso-
Can coffee make you feel cold?
Coffee contains caffeine, which causes diuresis (increased urination) and Vasoconstriction (constriction of the blood vessels). With blood vessel constriction, less blood gets to your limbs causing some people (especially smokers) to feel cold.
What is the medical term meaning lack of blood vessels?
Ischemia is a temporary, local deficiency of blood supply due to obstruction or constriction of a blood vessel.
What is the surgical widening of a constricted heart valve called?
An angioplasty is the widening of a narrowed blood vessel. A stent is a tube inserted to prevent constriction.
What is a vessel with a thick layer of smooth muscle and elastic fibers that allow for expansion?
An artery is a vessel with a thick medial layer, consisting of smooth muscle to allow for constriction or dilation in order to control blood flow through the vessel.
What is the medical term for blood stopping?
The medical term for blood stopping is hemostasis, which is the body's natural process of preventing and stopping bleeding. It involves blood vessel constriction, platelet aggregation, and blood clot formation to seal off the damaged blood vessel.
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 is the effector in blood pressure?
no one knows
When there is increased resistance then arteriolar constriction and pressure drops?
Resistance changes dramatically with changes in diameter of blood vessels (arterioles are one type of blood vessel). If you INCREASE the diameter of the arteriole, you DECREASE the resistance and thus DECREASE the blood pressure.
What is vasoconstriction?
Vasoconstriction is the constriction or narrowing of blood vessels by small muscles in their walls, slowing or blocking blood flow. Vasoconstriction is the constriction of blood vessels that increases blood pressure.
Blood pressure is affected by constriction and dilation of?
Arteries and blood vessels.
