Question

Which of the following steps, is the correct order of tubular reabsorption?

• A. 1. Capillary wall, 2. Cytosol, 3. Basolateral cell membrane, 4. Interstitial fluid, 5. Luminal cell membrane
• B. 1. Luminal cell membrane, 2. Interstitial fluid, 3. Basolateral cell membrane, 4. Cytosol, 5. Capillary wall
• C. 1. Luminal cell membrane, 2. Cytosol, 3. Basolateral cell membrane, 4. Interstitial fluid, 5. Capillary wall
• D. 1. Basolateral cell membrane, 2. Cytosol, 3. Luminal cell membrane, 4. Interstitial fluid, 5. Capillary wall
• E. 1. Basolateral cell membrane, 2. Cytosol, 3. Capillary wall, 4. Interstitial fluid, 5.Luminal cell membrane

Answer 1

The correct option is C 1. Luminal cell membrane, 2. Cytosol, 3. Basolateral cell membrane, 4. Interstitial fluid, 5. Capillary wall

To be reabsorbed (moved from the filtrate to the plasma), a substance must traverse five distinct barriers. They are 1. Luminal cell membrane, 2. Cytosol, 3. Basolateral cell membrane, 4. Interstitial fluid, 5. Capillary wall
