Question

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

Options

• Pisces and amphibians

•  Amphibians and reptiles

• Amphibians only

• Pisces only

Answer 1

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.
