Expansion
Glomerulus, Loop (of Henle), Ascending limb, Renal cortex collecting duct, Collecting Duct
Expansion
- G — Glomerulus (filtration; produces ~180 L/day of filtrate)
- PCT — Proximal Convoluted Tubule (bulk reabsorption: 65% Na⁺, glucose, amino acids, HCO3⁻)
- L — Loop of Henle descending limb (water reabsorption; concentrating segment)
- A — Ascending limb of Loop of Henle (Na⁺/K⁺/2Cl⁻ cotransport; impermeable to water)
- DCT — Distal Convoluted Tubule (fine-tuning of Na⁺/Ca²⁺; aldosterone acts here)
- CD — Collecting Duct (water reabsorption under ADH; acid-base regulation)
