Colloid osmotic pressure in plasma is fairly constant in a healthy person. How would protein starvation affect this pressure? How may a very high-protein diet affect this pressure? Suppose a person is suffering from an imbalance that causes an increase in colloid osmotic pressure from the typical 25 mm Hg to 30 mm Hg. Calculate the effect on net fluid flow across the capillary. What negative
health consequences could result?
What will be an ideal response?
Protein starvation would reduce this pressure whereas excess protein would increase this pressure. Absorption
would be affected in this way: $in = $IF - $cap.
Assuming $IF = 0 mm Hg, $in = -30 mm Hg, favoring absorption. This is a 20% increase in absorption pressure.
This would raise blood volume and blood pressure over normal.
