At what rate do kidneys filter impurities?

Human kidney can produce urine nearly ..........times more concentrated than the initial filtrate.  10 timestwo times4 times1/5th times

In the kidney, very large volumes of water and solutes are filtered across the filtration membrane because:W) plasma proteins exert an osmotic effectX) filtrate in the space of the Bowman's capsule exerts a high hydrostatic pressureY) glomerular capillary endothelium is thick endotheliumZ) glomerular hydrostatic pressure (blood pressure) is highQuestion 46Select one:a.if only W, X and Y are correctb.if only W and Y are correctc.if only X and Z are correctd.if only Z is correcte.if all are correct

What is a renal threshold?Group of answer choicesThe concentration of a substance in the blood above which it appears in the urineThe maximum possible rate of filtration at the glomerulusThe maximum amount of urine the kidney can make in one dayThe highest possible concentration of urine that the kidney can produce when the body is under water stress
