Title: Respiratory Passages Post by: jackiesivak on Nov 30, 2013 Phil is stung on his cheek by a wasp. Because Phil is allergic to wasp venom, his throat begins to swell and his respiratory passages constrict. Would acetylcholine or epinephrine be more helpful in relieving his symptoms? Why?

EDIT: Sorry, Padre beat me :P Hi, Well what is each used for? Acetylcholine is a neutrotransmitter which triggers muscle contraction; I don't think that'd help Phil with his constricted airways! Epinephrine (adrenaline) is able to bind to beta2 adrenergic receptors in bronchial smooth muscle leading to muscle relaxation. That sounds like a better idea. In fact, this is what EpiPens do for allergic reactions. |
