Vedclass · Answer

(D) In $Pisces$ (fishes),the heart is two-chambered,consisting of one atrium and one ventricle. It pumps deoxygenated blood to the gills for oxygenation,and this oxygenated blood then goes directly to the rest of the body without returning to the heart. Therefore,the heart in $Pisces$ only pumps deoxygenated blood. In contrast,amphibians,reptiles,birds,and mammals have hearts that pump oxygenated blood to the body tissues.

In which of the following vertebrate group/groups,heart does not pump oxygenated blood to different parts of the body?
