From my understanding, angiotensin II raises the filtration fraction (constriction of efferent arteriole) which raises the osmotic pressure and lowers the hydrostatic pressure, thus causing an increase in proximal tubular reabsorption. So does ANP also do this since it raises the filtration fraction also? (Dilation afferent, constriction efferent). This all just seems a little counter intuitive to me.
