Answer #1

Hydrostatic pressure of the glomerulus = 55mmHg

Hydrostatic pressure of the Bowman’s capsule = 15mmHg\

Osmotic pressure of the glomerulus = 30mmHg.

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

Net Filtration pressure = 55 - 30 - 15 +0 = +10 mmHg

Osmotic pressure of the Bowmen's capsule is zero because no protein or albumin has filtered from the blood into the Bowmens capsule.

Pressure favoring filtration are:
-glomerular 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....
