Chapter 48.2, Problem 1R
Summary Introduction
To review:
The influence of directionality of blood and water flow on opposite side of fish gill membranes on the maximum exchange of oxygen when the rates of perfusion and ventilation are constant.
Introduction:
Gills are the major respiratory organs in fishes. Fishes have the ability to pull oxygen-rich water from the surrounding area into their mouths and transporting them to gills which help in the exchange of oxygen between water and blood.
