Questions and Answers

What makes the glomerular capillary membrane different from other capillary membranes?

  • It has three layers instead of two. (correct)
  • It filters several hundred times less water and solutes.
  • It has larger fenestrations than other capillaries.
  • It is surrounded by a layer of epithelial cells.

    • What is the function of the layer of epithelial cells (podocytes) surrounding the outer surface of the glomerular capillary basement membrane?

  • To perforate the endothelium with small holes called fenestrae.
  • To form the filtration barrier with the other layers. (correct)
  • To filter large amounts of water and small solutes.
  • To hinder the passage of plasma proteins.

    • Why does the glomerular capillary membrane filter several hundred times as much water and solutes as the usual capillary membrane?

  • Because it is surrounded by a layer of epithelial cells.
  • Because it consists of a meshwork of collagen and proteoglycan fibrillae.
  • Because of its special characteristics and three-layer structure. (correct)
  • Due to the smaller fenestrations in the endothelium.

    • What hinders the passage of plasma proteins through the capillary endothelium?
