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
![Page 8: Renal System Histology and Models](https://reader035.vdocument.in/reader035/viewer/2022062408/5681334d550346895d9a52c5/html5/thumbnails/8.jpg)

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.

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

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.

• Glomerulus – (simple squamous epithelium)
• Convoluted tubules– (simple cuboidal epithelium)
