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.
Step-by-step 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.
