In case of moderate hypotension or hypovolemia, a number of adaptative systemic and intrarenal responses preserve renal perfusion and filtration rates, particularly by inducing a marked reduction in preglomerular arteriolar resistance and an increase in postglomerular resistance. However, these mechanisms are… CONTINUE READING
