RENAL HANDLING OF NaCL

Dr. Imalingat Julius

The material outlines the three core renal processes—glomerular filtration, selective reabsorption, and secretion—and details the contributions of each nephron segment. Cellular mechanisms for sodium, chloride, and water transport are explained, including the roles of Na/K‑ATPase, Na/H exchangers, and epithelial sodium channels. It also discusses bicarbonate and glucose handling, the principle of osmotic diuresis, and how loop and thiazide diuretics target specific transporters. The influence of aldosterone on distal tubular transport and the actions of potassium‑sparing agents are highlighted. The presentation concludes with clinical implications of these transport pathways.
