Expert Solution

Step 1

4.ans) Norepinephrine is indicated for blodd pressure control in certain acute hypotensive states.

Norepinephrine release is lowest during sleep ,rises during weekfulness and reaches much highers levels during situations of stress or danger in so called fight or flight response.

Epinephrine is a hormone and neurotransmitter used to treat allergic reactions,to restore cardiac rhythm,and to control mucosal congestion,glucoma,and asthma.

A) HEART RATE IS ADRENALINE

B)Heart contractility by DAP(ALPHA adrenegic effect)

C)diamter of bronchile by Epinephrine

D)pupil diamter largely by norepinephrine
