  1. Renal System Histology and Models

  2. Renal system in cat: • Kidney • Ureter • Urinary bladder

  3. Kidney Ureter

  4. Kidney Ureter Urinary bladder

  5. UretersUrinary Bladder

  6. Rugae inside urinary bladder that was cut open

  7. Spleen • Adrenal gland • Kidney • Renal artery • Ureter • Urinary bladder

  8. Adrenal gland • Kidney • Ureter • Urinary bladder • Prostate gland • Urethra

  11. Kidney Regions • The kidney is divided into three REGIONS. • If the question asks you to name the REGION, the answer is one of the below: • CORTEX • MEDULLA • RENAL PELVIS

  12. REGIONS Cortex Medulla Renal Pelvis

  13. Kidney Structures • If the question asks you to name the STRUCTURE, it is one of the below: • Within the cortex, you will find the glomeruli and the proximal and distal convoluted tubules. • Within the medulla you will find the loops of Henle, collecting tubules, the pyramids and the columns (pale area between the pyramids). • Within the renal pelvis you will find the hilus, which branches into the major calyxes, which branch into the minor calyxes.

  14. On this model you need to know the regions, vessels, and the following structures: Pyramids Hilus Ureter Major calyx Minor calyx

  15. Hilus Major calyx Minor calyx Ureter

  16. Renal artery Segmental artery Interlobar artery Interlobular artery Arcuate artery

  17. Interlobar artery Interlobular artery Arcuate artery

  18. REGIONS Cortex Medulla Renal pelvis

  19. STRUCTURES Pyramids Major calyx Minor calyx Hilus Ureter

  20. VESSELS Interlobular artery Arcuate artery Interlobar artery Segmental artery Renal artery

  21. KIDNEY MODEL • Glomerulus • Proximal convoluted tubule • Descending loop of the nephron • Thick segment • Thin segment • Ascending loop of the nephron • Thick segment • Thin segment • Distal convoluted tubule • Collecting tubule (where urine is most similar to the bladder) • Vasa recta

  22. Glomerulus Vasa recta

  23. Distal convoluted tubule • Proximal convoluted tubule • Glomerulus • Descending loop of the Nephron • Ascending loop of the nephron • Collecting tubule (where the fluid is most similar to urine found in the bladder)

  24. Study Tip: To get oriented, always start at the glomerulus and run your finger down the proximal convoluted tubule. When it loops back up and thickens, you are now at the distal convoluted tubule. • Thick segment of the ascending loop of the nephron • Thick segment of the descending loop of the nephron • Thin segment of the ascending loop of the nephron • Thin segment of the descending loop of the nephron

  25. GLOMERULUS Efferent arteriole Afferent arteriole Glomerular capsule The glomerular space is where urine is most dissimilar to the urine in the bladder

  26. KIDNEY SLIDES • Glomerulus • Kidney tubules (simple cuboidal epithelium)

  27. Glomerulus Tubule Skip

  28. Tubule Glomerulus

  29. Kidney Tubule Glomerulus

  30. Pancreas: don’t get this confused with a glomerulus in the kidney!
