Answer 1

Fishes have three chambered heart which is generally composed of two atria and one ventricle.

Human heart is four chambered which is composed of two articles and two ventricles.

Answer 2

Here is your answer -

wrong ! Fishes have two chambered heart. One Atrium and One Ventricle.

- In fishes single circulation reported. In such types of Circulatory System blood moves from heart to gills where diffusion of gases occurs. Blood runs into whole body after diffusion and then returns back to the heart.

- Like in human, the atrium of fish's heart also receives deoxygenated blood hence known as Receiving Chamber while Ventricle pumps blood to gills that's why called as Distributing Chamber.

- Interesting fact : Fishes also die due to heart attack which is caused by high temperature.
