The difference between renal blood flow and renal plasma flow: First, they have different definitions, which can be well understood literally. Renal blood flow actually refers to the amount of whole blood flowing through the kidney per unit time, while renal plasma flow, refers to the amount of plasma flowing through the kidney per unit time. Plasma and whole blood are not the same, whole blood contains plasma and blood cells, common blood cells are red blood cells, white blood cells, platelets, etc.; second, is because plasma accounts for 55% of blood, so renal blood flow is greater than renal plasma flow, renal blood flow is about 1200-1400ml/min. and renal plasma flow is between 600-800ml/min; third, if renal Third, if renal blood flow increases further, the rise in plasma colloid osmotic pressure will slow down, but on the contrary, if renal plasma flow decreases, the rise in plasma colloid osmotic pressure will accelerate.
