Q

Nephron Anatomy

A
  • Renal Corpuscle
    - Glomerulus:
    - Capillaries - filtration of blood (by pressure)
    - Bowman’s Capsule:
    - Filtered Urine Captured
    - 1st part of renal tubule
    - Renal Tubule: Carries filtered fluid
    - Proximal
    - Loop of Henle
    - Distal
    - Collecting Duct
    - Collecting Ducts Become:
    - Renal Pelvis
    - Ureter
    - Bladder
    - Urethra
