Amphibian heart and fish heart
How dissimilar is the amphibian heart from the fish heart?
Expert
The fish heart has just two chambers, a ventricle and an atrium, and the blood that comes to it is purely venous.
In amphibians, there are three heart chambers (that is, a second atrium is also present) and there is an arterial blood coming from lungs; in such animals the heart has two atria (one which gets blood from the body and other which gets blood from lungs) and one ventricle; arterial blood mixes with the venous blood in ventricle which in turn pumps the blood to lungs and to the systemic circulation.
