The back-pressure in the Bowman's capsule is 15 mm Hg. There, the net force, AP, is 40 mm Hg, driving the filtrate into the capsule 2. The glomerulus filters out all proteins and large, suspended particles.

What is the total pressure and osmotic driving force moving fluid into the capsule? Proximal tubule worksheet The proximal tubule absorbs 2/3 of the NaCI and 2/3 of the water of the glomerular filtrate 1. The concentration of NaCI in the filtrate is 150 mM. What is the concentration of the mucosal solution as it exits the proximal tubule? 2. What is the approximate osmolarity of the filtrate. given that NaCI is the primary solute in the filtrate? 3. What is the approximate osmolarity of the mucosal solution as it exits the proximal tubule?

Explanation / Answer

1. Net force = Pressure Glomerulus - Pressure Capsule

=55 - 15 = 40

therefore net force is 40mmHg

2. It is given that the glomerulus filters out all proteins and large, suspended particles, therefore the absence of proteins in Bowman’s space (the lumen within Bowman’s capsule) results colloid OP in the capsule near zero.

3. Net OP would be the difference of glomerulus colloid OP and capsule colloid OP

Therefore, Net OP = 30-0 =30mmHg and its direction would be out of the capsule

4. As explained above the absence of proteins in Bowman’s space (the lumen within Bowman’s capsule) results in an osmotic pressure near zero.
