CVS: blood flow Flashcards
what are the three layers of blood vessels and their properties
what are the major types of blood vessels and the pressure of blood through them
describe pressure changes in arteries vs veins
describe what it means that the cvs is a series of bags
what is the windkessel effect
what is elastic recoil? how does it keep blood moving?
what is the venous return system?
whats the role of venules vs valves vs veins
what are two types of vessels in capillary beds
what is an arteriovenous shunt
what is the role of true capillaries
what happens in cap bed with open vs closed sphincters
what two factors determine flow
how does pressure gradient impact flow
describe the pressure gradient of cvs
what is poiseuilles law
what is the only factor discussed in poiseulles law that actually changes in blood vessels
how does resistance change with vessel radius
vasoconstriction effect on blood flow
vasodilation effect on blood flow
how does flow get distributed when const/dil happens in one of the vessels
what factors impact arteriolar resistance
what is myogenic autoregulation
what are paracrines
HOW DOES SYMP CONTROL IMPACT RESISTANCE
what is active hyperemia
what is reactive hyperemia? when does it occur?
norepinephrine on receptors does what to arteries
how does norepinephrine lead to arteriolar contraction
what does it mean to say that calcium oscillations control vascular smooth muscle cell contraction
how can you control flow between vein and artery bags
what allows for large changes in length during contraction
what are the contractile proteins in smooth muscle
