Question
Chapter 24, Problem 16RQ
Summary Introduction
To define: Countercurrent flow in relation to gills of fishes.
Introduction: Fishes are defined as the aquatic vertebrates that have gills and appendages in the form of fins. They have excellent visual and olfactory senses. The gills of fishes are very effective in oxygen extraction even when a very low amount of oxygen is present.
