Answer #1

A. 15 mmHg

Explanation:

glomerular capillary hydrostatic pressure = 60 mmHg

glomerular colloid osmotic pressure = 29 mmHg

capsular hydrostatic pressure = 16 mmHg

capsular colloid osmotic pressure = 0 mmHg

Net filteration pressure= glomerular capillary hydrostatic pressure - glomerular colloid osmotic pressure - capsular hydrostatic pressure + capsular colloid osmotic pressure.

Net Filtration pressure = 60 - 16- 29 + 0 = 15 mmHg

Pressure favoring filtration are:
-glomerular capillary hydrostatic pressure
-capsular colloid osmotic pressure

Pressure opposing filtration are:
- glomerular colloid osmotic pressure
- capsular hydrostatic pressure

How do the Starling forces affect filtration or reabsorption? A) Colloid osmotic pressure causes osmosis due to large protein present in the plasma that cannot cross the capillary membrane. This force draws fluid back into the capillary. B) Osmotic force due to interstitial-fluid protein concentration occurs when there is a large concentration of Na+ in the interstitial space, as is the case in the nephron. C) Capillary hydrostatic pressure causes filtration to occur across the entire length of the capillary....
