Answer to Question #143260 in Zoology for Zoology#

Question

Discuss the basic blood flow of general fishes and how does their circulatory system work

Answer 1

In fish, the heart only has one atrium and one ventricle. The oxygen-depleted blood that returns from the body enters the atrium, and then the ventricle, and is then pumped out to the gills where the blood is oxygenated, and then it continues through the rest of the body.
