Question

How does the heart of an amphibian differ from that of reptile?

Answer 1

Amphibians and Reptiles. Amphibians and reptiles, by contrast, have a three-chambered heart. The three-chambered heart consists of two atria and one ventricle. ... Both atria empty into the single ventricle, mixing the oxygen-rich blood returning from the lungs with the oxygen-depleted blood from the body tissues.

Answer 2

While reptiles and amphibians have a three-chambered heart with two atria and one ventricle, reptiles' ventricle is partially/incompletely divided by a septum.

Explanation:

• Deoxygenated blood from all part of the body reaches the right atrium, while the oxygenated blood from the lungs enters the left atrium. During contraction, blood from both the atria enters the ventricle.
• From the ventricle, blood is pumped to the lungs as well as to other parts of the body.
• Recent studies on reptilian hearts have suggested that hardly any mixing of pure and impure blood occur in the ventricle and it is due to the presence of 'subchambers' in the ventricle.
• Note: The reptiles crocodiles have four-chambered heart.
