Describe the circulatory system in a fish.
Fish has a two-chambered heart-one atrium and one ventricle. In fish, heart pumps blood to the gills where oxygenation of blood takes place. The gills send the oxygenated blood to all the parts of the fish where oxygen is utilized and carbon dioxide enters into it making it deoxygenated. The deoxygenated blood is transported to the heart where it is pumped into the gills.
