Nephron Structure and the Process of Urine Formation: A Visual Explainer
A single infographic tracing blood flow through the nephron and the three-stage process — filtration, reabsorption and secretion — that converts blood plasma into urine.
📌 Revision Pointers
Glomerulus → Bowman's capsule: glomerular filtration pushes water, glucose, salts & urea out of blood
PCT → Loop of Henle → DCT: tubular reabsorption reclaims ~65–70% of the filtrate and fine-tunes water/ion balance
DCT & collecting duct: tubular secretion adds H⁺, K⁺ & ammonia; ADH controls the final water reabsorption
Visual flowchart of the nephron's structural parts in sequence, each labelled with the urine-formation stage occurring there, plus the peritubular capillary return pathway.
💭 Conclusion
A high-yield Prelims diagram topic — expect questions on the nephron's part sequence, the three urine-formation stages, and which hormone (ADH) controls final water reabsorption.
