Cortex
Medulla

3. kidney General structure Capsule： D.C.T labyrinth
Cortex：medullary rays
renal column
Medulla：10-18 renal pyramids

4. Medulla
Medullary rays
labyrinth

5. Uriniferous tubules Nephron renal corpuscle glomerulus Bowman capsule
renal tubules proximal tubule
thin segment
distal tubule
Collecting tubule： cortical
medullary
papillary
Loop of Henle

6. Cortical labyrinth（迷路）: renal corpuscle+convoluted renal tubules
Medullary rays（髓放线）: straight renal tubules+collecting tubules

7. Renal corpuscle （肾小体） Located in the cortical labyrinth
Glomerulus（血管球）
Bowman capsule（肾小囊）: parietal layer– simple squamous epi.
visceral layer-- podocyte

8. Distal
Proximal convoluted tubules: acidophilic,brush border,irregular
Distal convoluted tubules: less acidophilic, flatter cells, regular

9. In the medullary rays:
Collecting tubule
Distal straight tubule
Proximal straight tubule
