What is structure #11?
Outer medullary collecting duct
2 is pointing to the…
Minor calyces
What is structure #3?
Thick descending loop of Henle
(aka proximal straight tubule)
What structures make up the renal corpuscule?
Bowman’s capsule + glomerular capillaries
What is structure #6?
Thick ascending Loop of Henle
(aka distal straight tubule)
14 is pointing to the…
The cortex
Contains the cortical labyrinth, medullary rays, and renal columns
List the steps in the path that urine takes from Bowman’s space to the ureter
- Bowman’s space
- Proximal convluted tubule
- Thick descending limb of the LOH (proximal straight tubule)
- Thin descending limb of the LOH
- Thin ascending limb of the LOH
- Thick ascending limb of the LOD (distal straight tubule)
- Macula densa - part of the juxtaglomerular apparatus
- Distal convluted tubule
- Collecting tubule
- Cortical collecting duct
- Medullary collecting duct
- Minor calyx

1 is pointing to the…
Renal capsule
What is structure #10?
Cortical collecting duct
What is the functional unit of the kidney?
Nephron
Nephron = renal corpuscule + renal tubules
What structures make up the medullary rays?
Straight tubules + collecting tubules + collecting ducts
What structures make up the cortical labyrinth?
Renal corpuscules + convluted tubules
List the steps in the path that blood takes through the kidney, starting with the renal artery and ending with the renal vein
- Renal artery
- Segmental arteries
- Interlobar arteries
- Arcuate arteries
- Interlobular arteries
- Afferent arterioles (enters the renal corpuscule)
- Glomerular capillaries
- Efferent arterioles (leaves the renal corpuscule)
- Peritubular arteries (cortex) + Descending vasa recta (medulla)
- Interlobular veins + Ascending vasa recta
- Arcuate veins
- Interlobar veins
- Segmental veins
- Renal vein
- IVC
Which one of the following is part of the filtration apparatus?

B. Mesangial cells
C. Podocytes
D. Juxtaglomerular cells
E. Macula densa cells
C. Podocytes
7 is pointing to the…
Fat in the renal sinus
What structures make up the renal corpuscule?
Bowman’s Capsule + Glomerular Capillary tuft
What is structure #5?
Thin ascending Loop of Henle
What structures make up the lobe of the kidney?
Medullary pyramid + associated renal cortex
What structures make up the filtration apparatus (permeability barrier) in the glomerular corpuscule?
Fenestrated endothelial cells
Foot processes of the podocytes w/ slit diaphragms
Glomerular basement membrane
What is structure #1?
Renal corpuscule
What structures make up the renal columns?
Cortical regions of the kidney that extend between the pyramids of the medulla
What is structure #4?
Thin descending Loop of Henle
13 is pointing to the…
Medullary pyramids
(The medulla is made up of the pyramids)
What is structure #12?
Inner medullary collecting duct
