Question 5: Matching Question. Match each descriptor or statement on the left to the single best answer option listed on the right. Answer options can be used once, more than once, or not at all. 1. Region of the nephron that contains the NKCC ion transport proteins critical to establishing the hyperosmotic gradient in the medullary interstitium in the kidney. 2. Region of the nephron where parathyroid hormone (PTH) acts to inhibit phosphate ion reasbsorption 3. Structure that receives the ultrafiltrate from multiple nephrons and drains its contents to the renal pelvis 1. Ascending loop of Henle 4. The component of the renal blood supply that mointains the hyperosmotic gradient in the 2. Bowman's capsule interstitium of the renal medulla 3. Collecting duct 5. The component of the nephron that, along with 4. Descending loop of Henle the glomerular capillary, forms the renal corpuscle or "filtering unit" of each functional unit in 5. Distal convoluted tubule the kidney 6. Glomerular capililary 6. The epithelium where vasopressin inserts 7. Loop of Henle aquaporin 2 channels and urea transporters that move water and urea back to the interstitium 8. Peritubular capillary 9. Proximal convoluted tubule 7. The segment of the nephron responsible for re-obsorbing the bulk of the fluid, ions, and 10. Renal artery nutrients returned to the body from the ultrafiltrate each day. 11. Renal Vein 12. Vasa recta capillary 8. The segment of the nephron that creates the hyperosmotic gradient within the interstitium of the renal medulla. 9. The segment of the nephron that receives hypoosmotic ultrafiltrate and, because its walls are permeable to and reabsorb ions [NaCl] but are impermeable to water and retain fluid in the ultrafiltrate, will make that ultrafiltrate the most hypoosmotic it becomes while moving through the nephron to the collecting duct. 10. The segment of the nephron that receives an isosmotic ultrafiltrate, and converts it to a very hyperosmotic ultrafiltrate because its walis are permeable to and absorb water from, but are impermeable to, so retain ions in, the ultrafiltrate..
