Question

A disorder which disrupts the ability of the vasculature to maintain a physiological barrier is most likely to involve which one of the following?

a. The apical surface
b. The basal surface
c. The basement membrane
d. Tight junctions
e. Desmosomes

Answer 1

A disorder affecting the vasculature's ability to maintain a physiological barrier likely involves the basement membrane, which is fundamental for vessel strength, flexibility, and permeability. The option (C) is correct.

Step-by-step explanation:

A disorder that disrupts the ability of the vasculature to maintain a physiological barrier is most likely to involve the basement membrane. The basement membrane binds the endothelium to connective tissue, providing strength while maintaining flexibility, and is crucial for the permeability of blood vessels.

This membrane works in conjunction with tight junctions which establish a barrier to prevent extracellular passage of materials between cells. Therefore, option (C) is correct.
