How many chambers are present in the heart of (a) fish and (b) amphibians? How many times does
blood flow through the heart in fish?
Answers
Fish :-
They have two chambered heart.
In fish, the heart only has one atrium and one ventricle. The oxygen-depleted blood that returns from the body enters the atrium, and then the ventricle, and is then pumped out to the gills where the blood is oxygenated, and then it continues through the rest of the body.
________________________________
Amphibians :-
They have three chambered heart.
Amphibians have two circulatory routes: one for oxygenation of the blood through the lungs and skin, and the other to take oxygen to the rest of the body. The blood is pumped from a three-chambered heart with two atria and a single ventricle.
