WebThe amounts reabsorbed are regulated by parathyroid hormone (PTH), which both inhibits the reabsorption of PO43- in the proximal convoluted tubule (PCT) & stimulates Ca2+ reabsorption in the distal convoluted tubule (DCT) 24.6.37 Describe the reabsorption of water, and compare how it is regulated by the actions of aldosterone and antidiuretic … WebReabsorption and Secretion in the PCT. Largest amount of solute and water reabsorbtion. Secretes variable amouts of H+, NH4+ and urea. Most solute reabsorption uses Na+. Na+/H+ antiporter cause Na+ to be absorbed and H+ to be secreted. Solute reabsorbtion promotes osmosis- creates osmotic gradient.
