Antworten
-
Both
-
Vasoconstrictor
-
Vasodilator
Frage 2
Frage
Heat-induced increases in blood flow are due to [blank_start]__________[blank_end] of skin arterioles and [blank_start]__________[blank_end] of arteriovenous anastomoses.
Antworten
-
Vasodilation
-
Vasoconstriction
-
Opening up
-
Closing down
Frage 3
Frage
[blank_start]__________[blank_end] is the (a?) neurotransmitter for vasodilator nerves, but nitric oxide mediates its vasodilator action. Cholinergic nerves that induce sweating may be the same ones that induce vasodilation. [blank_start]__________[blank_end] in sweat may also contribute to the vasodilation (via nitric oxide).
