The first step in urine formation in which urine is filtered from afferent arterioles in the bowman's capsule of a nephron.
The second step in urine formation in which valuable water and solutes are reabsorbed back into the blood.
The third step in urine formation in which filtrate moves toward collecting ducts; secretion helps maintain the body's acid-base balance.
