Question

Quizplus · Accepted Answer

The three processes necessary for the formation of urine are filtration, reabsorption, and secretion. Filtration involves the movement of fluid and solutes from the blood into the renal tubules. Reabsorption involves the movement of certain substances such as glucose and amino acids back into the blood. Secretion involves the movement of certain substances such as toxins and excess ions from the blood into the renal tubules to be excreted in the urine. Intake, concentration, and output are important aspects of fluid balance, but they are not the specific processes involved in the formation of urine. Chemical, muscular, and neural action as well as arterioles, nephrons, and venules are also involved in renal function, but they do not describe the specific processes involved in urine formation.
