प्रश्न
In which of the following vertebrate group/groups, the heart does not pump oxygenated blood to different parts of the body?
पर्याय
Pisces and amphibians
Amphibians and reptiles
Amphibians only
Pisces only
उत्तर
Pisces only
Explanation -
This is due to the heart's solitary circulation, which pumps deoxygenated blood from all parts of the body into it. It is pumped from the heart to the gills, where it is oxygenated and distributed to all parts of the body. As a result, Pisces will not be receiving oxygenated blood.
