Question
Chapter 16, Problem 4RQ
Summary Introduction
Introduction:
Tubular secretion is the process in which substances from the plasma are transported to the renal tubule. It works in the direction opposite to the one in which tubular reabsorption works. It is an additional mechanism that provides entry to the plasma fluid into the tubules.
