Net Filtration pressure of glomerulus increases by 
Select and explain. 
A. Increase in Hydrostatic pressure of glomerullar capillary, B. Increase in Oncotic pressure of glomerullar capillary, C. Increase in Hydrostatic pressure of  Bowman's space, D. All of the above
A: Increase in Hydrostatic pressure of glomerullar capillary
Answer: A: Increase in Hydrostatic pressure of glomerullar capillary 
Explanation: GC - Glomerular capillary
BS - Bowman's space
P - Hydrostatic Pressure
π - Oncotic pressure
Net Filtration Pressure = (P GC - P BS ) + ( π  BS +  π GC )
