1

How many lobes make up the human kidney?

8-11

2

What are the components of the renal corpuscule?

- Glomerulus

- Mesangium

- Extraglomerular mesangial cells

- Bowman's capsule

- Macula densa

- Juxtaglomerular cells

 

3

What are the functions of mesangial cells?

- Contraction

- Phagocytosis

4

What is the structure of the Bowman's capsule?

- Visceral epithelium (podocytes)

- Parietal epithelium (squamous epithelium)

- Connection to PCT

5

What is the structure of podocytes?

- Cell body

- Primary foot process

- Secondary foot process (forms filtration slits)

6

What are the filtration barriers in the glomerulus?

1. Capillary endothelium

2. Basement membrane

3. Filtration slits (foot processes)

7

What type of epithelium makes up PCT and DCT?

Simple cuboidal epithelium

8

What is the difference between PCTs and DCTs?

- PCTs have brush borders while DCTs do not.

- DCT cells are smaller and cytoplasm stained less intensely than PCT cells.

9

What type of epithelium makes up the descending limb of the loop of Henle?

Simple squamous epithelium

10

What type of epithelium makes up the ascending limb of the loop of Henle?

Simple squamous epithelium

11

What type of epithelium makes up the collecting ducts?

Simple cuboidal epithelium

12

What type of epithelium makes up the urinary system?

Transitional epithelium
