Question

22. The hydrostatic pres the glomerular capillaries is a. 55 mmHg b10 mmHg c. 30 mmHg d. 15 mmHg 23. Which, if any, of the following will enhance glomerular filtration? a. filtration membrane is very thin and porous b. glomerular capillaries have a huge surface area c) glomerular blood pressure is much higher than that in other capillary beds both a and c e. all of the above 24. The juxtamedullary nephron ir -haracterized by all of the following excent a. long nephron loop b, glomerulus is further from the cortex-medulla junction laver to the cortex-medulla junction

Explanation / Answer

22) answer is a) 55 mmHg.

23) answer is e) all the above

Normal hydrostatic pressure is 55 mmHg

Net filteration is 10 mmHg.

Factors affecting GFR are;

Capillary permeability

Surface area

Hydrostatic and oncotic pressure.

Increased capillary permeability and surface area allow bulk of fluid to pass through it and hence increase in gfr occurs.

Increased hydrostatic pressure increses GFR as more fluid will be passed out.
