Options are tubular secretion, glomerular filtration, or tubular reabsorption.

1. Opposite process to tubular reabsorption

2. Water and solutes are forced from the blood into the glomerular capsule of the nephron

3. Water, glucose, amino acids, and needed ions are moved from the filtrate back into the blood

4. Aldosterone promotes sodium and thus water to move from the filtrate through the tubule cells into the blood

5. Antidiuretic hormone (ADH) promotes the movement of water from the filtrate back into the blood of the peritubular capillaries

6. Unneeded substances such as potassium, urea, and creatinine are moved from the blood of the peritubular capillaries into the filtrate
