Urinary System (Nephrons (Parts of Renal Tubules (Proximal convoluted…

- - - - Part of tubule closest to the glomerulus
    - - Part of tubule that is in medulla
    - - tubule part farthest away from glomerulus
  - - - Most abundant-85%
      - most of nephron is in cortex
    - - Long nephron loop
  - - - Varopressin is stored in the posterior pituitary. and helps water be reabsorbed.
- - - - Resorption is when the capillaries running next to the Tubules take back nutrients, water, and essential ions
      - Secretion is when the capillaries running next to the tubules move undesirable substances to the tubule
  - - - Hilus- Part of the kidney where the vessels and nerves enter.
      - Dense connective tissue covering- fibrous covering
    - - Cortical Structures
        
        Renal Corpuscle
      - Medullary structures
        
        Pyramids- Bundles of Renal Tubules
      - Calices
        
        Minor- collects urine from tubules; small
        
        Major- extension of the minor calices; collects urine from tubules
      - Renal Pelvis
        
        Calices end here; start of ureters
