Question

There is a complete separation of pulmonary and systemic circulation in amphibians and most reptiles. Amphibians only respire through their lungs. Amphibians and most reptiles have a four-chambered heart consisting of two atria and one ventricle. Diving reptiles can alter the pattern of blood circulation to bypass their lungs when submerged.1. True2. False

Answer 1

Answer:

False

Explanation:

Some amphibians can respire through other means including lungs. Take Frog for an example. Frog is an amphibian. When it is on land it respires through lungs but when it is in water it uses its skin for the respiration purpose. This respiration is termed as cutaneous respiration.

Species having four chambered heart have two atria and two ventricles in their heat.
