Explain the mechanism of urine formation
WebIn the collecting ducts, the apical surfaces of intercalated cells have proton pumps that actively secrete H + into the luminal, forming urine to remove it from the body. As hydrogen ions are pumped into the forming urine, it is buffered by bicarbonate (HCO 3– ), H 2 PO 4– (dihydrogen phosphate ion), or ammonia (forming NH 4+, ammonium ion). WebHaving reviewed the anatomy and microanatomy of the urinary system, now is the time to focus on the physiology. You will discover that different parts of the nephron utilize …
