Question

11. Explain each of these 4 forces, and mention if they contribute to, or oppose, glomerular filtration. Also draw AND label a simple diagram demonstrating the relationship of these 4 forces @ the renal corpuscle. And finally, set up an algebraic equation showing how all 4 forces contribute to Net Filtration Pressure. (ex: NFP = (A+b)-(C+d)) a. GHP – Glomerular Hydrostatic Pressure b. GOP – Glomerular Osmotic Pressure (the book calls it BCOP) c. CHP – Capsular Hydrostatic Pressure (the book calls it CsHP) d. COP - Capsular Osmotic Pressure (the book calls it CsOP)

Answer 1

Ans:+

Forces are

1) glomerular hydrostatic press:- it is pressure exserted by blood on the lateral walls of glomerulus which pushes fluid out of glomerulus.

2) capsular osmotic pressure:- as no protein is filtered out in capsule so it is 0

3) capsular hydrostatic pressure:-

Pressure excerted by filtrate over the glomerus to oppose filtration.

4) glomerular osmotic press:- pressure due to presence of proteins in the bowman's capsule.it oppose filtration.
