    • Uterus
    • Bladder
    • Urethra
  2. What are the 2 kinds of nephrons?
    • Corticol Nephrons
    • Juxtamedullary Nephrons

  7. What supplies blood to the glomerulus?
    Afferent arteriole
  8. What is glomerular filtration?
    As blood flows through the glomerular capillaries, protein-free plasma filters into the Bowman's capsule
  9. What drains the glomerulus of remaining blood?
    Efferent arteriole
  10. What is reabsorption?
    The movement of filtered solutes and water from the lumen of the renal tubules back into the plasma.
  11. What ensures the reabsorption of glucose?
    • Glucose carriers
    • Secondary active transport through sodium pumps
  12. What is ADH influenced by?
    • Osmolality
    • Volume & pressure of cardiovascular system
  13. What is the primary action of ADH?
    Increase permeability of the distal tubule and collecting duct to water
  14. How does ADH work?
    Binds to receptors in principle cells to cause reaction by opening aquaporins
  15. What controls aldosterone?
    Renin-angiotensin system
