I know in the heart beta 1 increases ca influx, increase ca atpase, and removes inhibition of phospholambam (spelling not sure). But how does beta 2 cause relaxation, esp beta 2 given to pregnant women to prevent uterine contractions? Thanks ahead of time.

kinda makes sense:
in cardiac myocytes ^ contractility & ^ hr = ^ CO
in smooth myocytes \/ contraction = \/ resistance = ^ flow
