Excretory System: Nephron - Part 1

Learn about the structure and function of the proximal convoluted tubule (PCT) in this 28-minute video lecture from NPTEL-NOC IITM. Explore renal physiology and urine processing, focusing on tubular reabsorption mechanisms including tight junctions, microvilli, active and passive transport, sodium-glucose co-transporters, and glucose transporters. Understand primary active transport, pinocytosis, transport maximum, glucose reabsorption threshold, and the reabsorption processes for chloride, urea, and bicarbonate. Discover how filtrate concentration changes across the PCT in this first part of the nephron series.
