Efferent aeriole constriction causes
Increased GFR
Decreased GFR Increases
GFR initially then decreases
Decreased GFR initially then increase
The efferent aerioles are blood vessels that are pa of the urinary tract of organisms. The efferent aerioles form from a convergence of the capillaries of the glomerulus. They play an impoant role in maintaining the glomerular filtration rate despite fluctuations in blood pressure.Ref: Ganong&;s review of medical physiology; 24th edition; page no; 679
