Question

During filtration, anything that is small enough to pass through all three layers of the filtration membrane will become part of the filtrate. Sometimes, the least porous layer of this membrane becomes clogged and then glomerulonephritis may occur. What is the name of the most porous layer of the filtration membrane?
A. Fenestrated endotheliumf
B. Iltration slits
C. Capsular epithelium
D. Visceral epithelium

Answer 1

Answer:

A Fenestrated endothelium

Explanation:

Fenestrated endothelium are pores that penetrate through the endothelial cells. The next layer is the glomerular basement membrane, a shared basement membrane between the two epithelia (endothelium and podocytes). Fenestrations are round or ovoid transcellular holes transcytoplasmic holes, specialized for their unique role as a prerequisite for filtration across the glomerular capillary wall. During filtration, anything that is small enough to pass through all three layers of the filtration membrane will become part of the filtrate.

The profound common type is found in organs including endocrine tissue (e.g, adrenal cortex), gastrointestinal mucosa, and renal peritubular capillaries. etc.
