Collloid osmotic pressure is a form of pressure exerted by the proteins in the blood plasma or interstitial fluid. Hydrostatic is the force generated by the pressure of fluids within or outside of the capillary on the capillary walls. 2 Question #2: What is the importance of colloid osmotic pressure in regulating fluid balance? Due to the way colloid osmotic pressure works it can displace water via albumin and protein pressure. This will tend to pull water into the circulatory system which would lead to more fluid in the vessels than outside of them. Colloid osmotic pressure works as the opposite force to hydrostatic pressure thus regulating fluids opposite of how hydrostatic pressure works. 3 Question #3: What color is the solution in the tubing? Blue 4 Question #4: What color is the solution in the beaker? Brown/orange color 5 Question #5: Explain the significance of the colors in each solution. What does this tell us about the permeability of the dialysis tubing? The tubing shows selective permeability. It was permeable to glucose and the iodine but not the starch. 6 Question #6: Was there a change in solution volume between the dialysis tubing and the water beaker? Why or why not; in your answer please discuss the forces responsible for the result. Yes this is due to the water molecules flowing through the semi permiable membrane into the dialysis tube through osmosis. This is explained due the solvent molecules traveling from the higher concentration to the lower concentration through that semi perm membrane. 7 For the next few questions, think back to your text, chapter 20.3. Question #7: Is the dialysis tubing behaving more like the glomerular capillaries, or more like the peritubular capillaries? Defend your answer by discussing the types of fluid
