Answer:
The epinephrine reaction is a decrease in the rate of blood flow in the arteriole and capillary, due to a phenomenon of vasoconstriction.
Explanation:
Epinephrine, or adrenaline, is a hormone produced by the adrenal cortex, which acts as a neurotransmitter for the sympathetic nervous system.
One of the effects of epinephrine is the <u>vasoconstriction of blood vessels, predominantly arteries</u>. Vasoconstriction of arterioles and closure of capillaries is an effect of epinephrine that results in a decrease in the rate of blood flow at that level.
This response can be seen when exogenous epinephrine is used to control an allergic or anaphylactic reaction, counteracting the vasodilation that characterizes these conditions.
