n wat is the effect of alpha1 n beta2 receptors on T.P.R?n hence SBP or DBP?
TPR affects Diastolic BP.
Alpha causes constriction which will reduce vessel radius thus increasing TPR
Beta 2 will result in relaxation, which will increase vessel radius thus decreasing TPR.
Ex. When you get up off the chair, Alpha stimulation will occur, preventing sudden drop in BP by causing increase in TPR!
