Natalia Hernandez P.2 Digestive & Urinary System - Coggle Diagram

- - - - Glormerulus: capillaries w/ fenestrated (porous) endothelium; allow for efficient diffusion of filtrate (plasma fluid) formation
      - Glomerular capsule (bowman's capsule): surround glomerulus; two layers are parietal (simple squamous) & visceral (clings to glomerular capillaries; branching epithelial
        podocytes)
    - - 1. Proximal convoluted tubule: closest to corpuscle; Ccuboidal cells w/ dense microvilli that form brush border for increase surface area; reabsorption & secretion; confined to cortex
      - 2. Nephron loop (loop of Henle): U-shaped structure consisting of two limbs, descending so called descending thin limb, simple squamous epithelium & ascending, which is thick & thin and some areas, cuboidal or columnar
      - 3. Distal convoluted tubule: cuboidal w/ some micrpvilli, mostly secretory; confined to cortex; drains into collecting duct
    - - Collecting Duct: 2 cells are principal (have microvilli & maintain water and Na+ balance) & intercalated (cuboidal w/ lots of microvilli); receive filtrate from many nephrons; run through medullary pyramids
