Questions and Answers

What is the main reason for the high filtration rate across the glomerular capillary membrane?

  • Strong positive electrical charges associated with the proteoglycans
  • Large spaces in the basement membrane
  • Continuous epithelial cell layer
  • Presence of fenestrae in the capillary endothelium (correct)

What prevents filtration of plasma proteins across the glomerular capillary membrane?

  • Presence of fenestrae in the capillary endothelium
  • Continuous basement membrane
  • Strong negative electrical charges associated with the proteoglycans (correct)
  • Large spaces in the epithelial cell layer

What is the composition of the basement membrane in the glomerular capillary membrane?

  • Absence of collagen and proteoglycan fibrillae
