The statement "normally about 20 to 25 percent of the total cardiac output" is correct as the kidneys receive a high proportion of the cardiac output to ensure efficient filtration and removal of waste products from the blood. The other statements are incorrect as not all blood is filtered through the glomeruli and not all blood is used to supply renal tissue with nutrients (some of it is diverted to other organs via the renal vein). The statement "normally about 40 percent of the total cardiac output" is also incorrect, as it overestimates the proportion of blood that flows through the kidneys.
