Distal Tubule
1532
- Distal (convoluted) Tubule
- Physiologically-controlled reabsorption
- Aldosterone increases Na+ reabsorption and K+ secretion
- Reabsorption of sodium, calcium
- Na+ coupled to water reabsorption, increasing blood pressure
- Secretion of potassium
- Acid-base balance
- By secreting H+ and reabsorbing bicarbonate
- Reabsorption of sodium, calcium
- Antidiuretic hormone (ADH/vasopressin) increases water reabsorption via aquaporins
- Aldosterone increases Na+ reabsorption and K+ secretion
- Physiologically-controlled reabsorption
