Question

Which of the following is not a component of the filtration membrane of kidney?

• A. Filtration slits between podocytes
• B. Basement membrane
• C. Fenestrations in the wall of glomerulus
• D. Renal tubules

Answer 1

The correct option is D

Renal tubules

The Bowman's capsule has an outer epithelium of simple squamous epithelial cells called the parietal epithelial layer and an inner epithelial layer of what are called visceral cells. These cells fuse with the endothelial cells lining the glomerular capillaries. In between the endothelial cells and the visceral cells lies an additional layer called the glomerular basement membrane. All three of these layers together, form the glomerular filtration barrier.
