  • Filtration

    The first step in urine formation in which urine is filtered from afferent arterioles in the bowman's capsule of a nephron.

  • Reabsorption

    The second step in urine formation in which valuable water and solutes are reabsorbed back into the blood.

  • Secretion

    The third step in urine formation in which filtrate moves toward collecting ducts; secretion helps maintain the body's acid-base balance.
