16
Q

what adrenerigc receptor works witht he heart?

A

beta 1

17
Q

alpha one does what

A

vasoconstricts, urinary retenttion, and pupil dialtion

18
Q

what does alpha 2 do?

A

vasoconstircts

19
Q

What does Beta 1 do?

A

tachycardia - rate, electical pulse, and contraciton strength

20
Q

Beta 2 does what

A

bronchodialtion and vasodialation stops peristalsis

21
Q

What activates all alpha and beta receoptors

A

EPI

22
Q

What is epi reversal

A

vasocrstiction effect where the alpha blocker cancels the epi’s alpha effects adn only activates the beta receptors

23
Q

what is the vasovagal refelx?

A

NE activates the barorecptors which reduces heart rate and leading to opposite of what NE typically does
