  1. 5. Arteriole  Vessel carrying blood away from the glomerulus.
  2. 6. Kidney’s ability to keep GFR stable despite BP changes.
  3. 7. Membrane  Negatively charged layer restricting protein filtration.
  4. 8. Endothelium  Capillary layer containing filtration pores.
  5. 10. Filtration Rate  Rate at which fluid is filtered into Bowman’s capsule.
  6. 12. Specialized cells with foot processes forming filtration slits.
  7. 13. Plasma Flow  Amount of plasma entering the kidneys per minute.

Down
  1. 1. Fraction  Percentage of plasma that becomes filtrate (≈20%).
  2. 2. Mechanism  Smooth muscle response to stretch that stabilizes flow.
  3. 3. Recta  Capillary network essential for medullary concentration gradients.
  4. 4. Arteriole  Vessel bringing blood into the glomerulus.
  5. 9. II  Hormone that constricts efferent arterioles to maintain GFR.
  6. 11. Densa  NaCl‑sensing cells regulating GFR through feedback.
  7. 14. Filtration Pressure  Combined forces driving filtration across the membrane.
