List the flow (path) of an erythrocyte from the renal artery ending in the renal vein (assume the RBC stays in the blood vessels which is what should happen in normal physiology).

Answer


Pathway of an erythrocyte

  • Renal artery
  • Segmental artery
  • Interlobar artery
  • Arcuate artery
  • Interlobular artery
  • Afferent arteriole
  • Glomerulus (glomerular capillaries)
  • Efferent arteriole
  • Peritubular capillaries and vasa recta
  • Interlobular vein
  • Arcuate vein
  • Interlobar vein
  • Segmental vein
  • Renal vein

- Abdominal aorta branches into renal artery that supllies the kidneys.
- Afferent arteriole supplies to the nephron, where it becomes glomerulus and reside in the Bowman's capsule.
- After filtration, blood moves out from glomerulus via efferent arteriole.
- Efferent arteriole becomes peritubular capillaries and vasa recta to surround the nephron.
- Renal vein drains deoxygenated blood from kidney into the inferior vena cava.
