1
Q
What affect does constriction of the afferent arteriole and constriction of the efferent arteriole (respectively) have on resistance, renal blood flow, GFR, glomerular hydrostatic pressure
A
Constriction of AA: Resistance: increased (afferent), RBF & GFR & Pg: all decrease
Constriction of EA: R: increased (efferent), RBF: decreased, GFR & Pg: increased
