Amphibian circulation categorization-double and incomplete

Why the amphibian circulation is categorized as double and incomplete?

E

Expert

Verified

The amphibian circulation is double as it is comprised of systemic and pulmonary circulations: correspondingly, heart-tissues-heart and heart-lungs-heart. As amphibians contain only one ventricle in the heart, the venous blood taken from tissues and arterial blood coming from the lungs are mixed in the ventricle which then pumps the mix back to the systemic and to the pulmonary circulations. The amphibian circulation is categorized as incomplete since venous and arterial blood mix in the circuit.

The blood oxygenation in amphibians takes place as well in the systemic circulation as their skin is a gas exchange organ.
