1. The first segment of these tubules is the proximal convoluted tubule . 2. Atrial natriuretic peptide causes the distal convoluted tubule to secrete more sodium. 3. This hypotonic filtrate is passed to the distal convoluted tubule in the renal cortex. 4. Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. 5. The urinary pole is where the corpuscle opens into the lumen of the proximal convoluted tubule . 6. The distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule. 7. The distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule . 8. The renal organic anion transporters OAT1, S2 segment of the proximal convoluted tubules of the kidneys. 9. Much of the ion transport taking place in the distal convoluted tubule is regulated by the endocrine system. 10. In the presence of parathyroid hormone, the distal convoluted tubule reabsorbs more calcium and secretes more phosphate.
