The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The glomerular filtration membrane<\/strong> is a critical structure in the kidney that selectively filters blood to form urine while retaining essential cells and proteins. The membrane consists of three main layers:<\/p>\n\n\n\n

    \n
  1. Fenestrated Endothelium of Glomerular Capillaries<\/strong> \u2013 This is the innermost layer. The endothelial cells have large filtration pores (fenestrations) that allow passage of water, electrolytes, glucose, and small molecules while blocking blood cells.<\/li>\n\n\n\n
  2. Basement Membrane<\/strong> \u2013 This middle layer is a dense network of negatively charged proteins, which repels large anions and plasma proteins, preventing their filtration.<\/li>\n\n\n\n
  3. Filtration Slits (Slit Diaphragm) of Podocytes<\/strong> \u2013 The outermost layer consists of podocytes with foot processes (pedicels) that interdigitate to form narrow filtration slits, further restricting large molecules.<\/li>\n<\/ol>\n\n\n\n

    Labeling the Components<\/strong><\/h3>\n\n\n\n
      \n
    1. Endothelial cell of glomerular capillary<\/strong> \u2013 Located at the innermost part of the filtration membrane, containing filtration pores.<\/li>\n\n\n\n
    2. Filtration pore<\/strong> \u2013 Gaps in the endothelium that allow small solutes and water to pass.<\/li>\n\n\n\n
    3. Basement membrane<\/strong> \u2013 The second layer, acting as a charge-based and size-based filtration barrier.<\/li>\n\n\n\n
    4. Filtration slit<\/strong> \u2013 Small gaps formed between podocyte foot processes that further filter the fluid.<\/li>\n\n\n\n
    5. Foot process of podocyte<\/strong> \u2013 Extensions of podocytes wrapping around capillaries.<\/li>\n<\/ol>\n\n\n\n

      Substances and Their Filtration<\/strong><\/h3>\n\n\n\n
        \n
      • Filtered through the membrane:<\/strong> Water, electrolytes (Na\u207a, K\u207a, Cl\u207b), glucose, amino acids, fatty acids, vitamins, urea, uric acid, and creatinine pass freely.<\/li>\n\n\n\n
      • Blocked by the membrane:<\/strong> Blood cells, plasma proteins, large anions, and protein-bound substances (hormones, minerals).<\/li>\n<\/ul>\n\n\n\n

        This selective permeability ensures that vital substances like proteins and blood cells remain in circulation, while waste and small molecules enter the filtrate for urine formation.<\/p>\n","protected":false},"excerpt":{"rendered":"
