Angiotensin II triggers vasoconstriction of the efferent arterioles at the nephron, which increases glomerular pressures and glomerular filtration rates. This is because the constriction of the efferent arterioles results in a decreased outflow of blood from the glomerulus, which increases the pressure within the glomerulus and therefore increases the filtration rate.
