  1. Renal System Histology and Models

  2. Types of kidney stones

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

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

  5. Trigone Prostate gland Urethra

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

  7. 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

  8. REGIONS Cortex Medulla Renal Pelvis

  9. 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 ducts, the pyramids and the columns (pale area between the pyramids). • Within the renal pelvis you will find the hilus, the major calyxes, which branch into the minor calyxes.

  10. Cortex: Glomerulus Proximal and Distal convoluted tubules Medulla: Loops of Henle Collecting duct Pyramids Columns Renal pelvis Hilus Major calyxes Minor calyxes

  11. Cortex: Glomerulus Proximal and Distal convoluted tubules Medulla: Loops of Henle Collecting duct Pyramids Columns Renal pelvis Hilus Major calyxes Minor calyxes

  12. Adrenal Cortex Adrenal Medulla Renal Cortex Renal Medulla Renal pelvis

  13. Pyramids Hilus Ureter Major calyx Minor calyx

  14. Pyramids Hilus Ureter Calyx

  15. Calyx Pyramids Hilus Kidney stones Ureter

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

  17. Interlobular artery Interlobar artery Segmental artery Renal artery Arcuate artery

  18. 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 duct • Vasa recta

  19. Glomerulus Vasa recta

  20. Distal convoluted tubule • Proximal convoluted tubule • Glomerulus • Descending loop of the Nephron • Ascending loop of the nephron • Collecting duct

  21. 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

  22. GLOMERULUS Efferent arteriole Afferent arteriole Glomerular capsule Macula densa
