Question

The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for which physiologic function to occur with fluids?

Answer 1

Answer:

The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for active transport processes to occur with fluids.

Explanation:

• The proximal tubule is a part of the nephron and it controls the "pH of the filtrate" by exchanging "hydrogen ions for bicarbonates".

• It also secretes organic acids like creatinine and bases to be mixed with the filtrate, so that it is neutralized.

• Thus it helps in  the transportation of the filtrate and is also responsible for absorption and re-absorption of the fluids.
