Question
Chapter 26, Problem 24RQ
Summary Introduction
To describe:
Two functions of countercurrent multiplication in the kidneys.
Concept introduction:
The countercurrent multiplication refers to exchange that occurs between the descending and ascending loop of Henle. The two loops are part of same tube that runs in opposite direction. This increases the effect of exchange as the fluid continues from one segment to another.
