Simulating Filtration.

The following refer to Activity 4: Simulating Filtration.
Using your results in Chart 4, which MWCO membrane had the greatest filtration rate?     

Explain the relationship between pore size and filtration rate.     



Which solute did not appear in the filtrate using any of the membranes?     

What is your prediction of the molecular weight of glucose compared to the other solutes in the solution?     

What happened when you increased the driving pressure?     



Explain why fluid flows from the capillaries of the kidneys into the kidney tubules.






How do you think a decrease in blood pressure would affect filtration in the kidneys?
