Question
Chapter 34, Problem 2MC
Summary Introduction
Introduction:
Gills are the respiratory structures found in lower order animals. Thus, the exchange of gases occurs between gills and blood. A fish creates continuous water current through its mouth, over gills and out of operculum using pumping movement by rapid swimming with its mouth open. Fishes have evolved a very efficient method for gas exchange using a process named as “countercurrent exchange”.

- The countercurrent exchange system for gills relies on diffusion to diffuse oxygen into the blood. This system works because the blood in the gills. a. increasing encounters [Select] b. decreasing water as the blood moves from [Select] a. arteries [Select] b. capillaries c.
