You will be using this Case Study which requires an understanding of both kidney function and blood buffering systems. It also gives you the opportunity to learn more specific details about some of the transport mechanisms in the distal and proximal convoluted tubules.
This case study was written by Ann T. Massey (Nell Hodgson Woodruff School of Nursing, Emory University, Atlanta, GA) and is posted on the Buffalo University National Center for Case Study Teaching in Science. Please go to the site: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=731&id=731 and download the case study from there.

I found the figures in the case study to be a little bit confusing. It shows the cell that would be part of the proximal and distal tubule walls.
Here are some figures that I found useful understanding which way the ions were being transported - and what they were being transported into and out of.
