Oh my goodness!! THANK YOU for these videos! I'm in an online course that provides nothing but notes and terribly inadequate diagrams. This is fantastic and massively helpful!!
When I read the book, I a confused about the areas in which the tubular reabsorption and secretion happen. Do they only happen at some particular areas of the tubule or all along it? Thank you.
