Question

A. Reptiles are known for having three
chambered heart. Which animal shows a
near four chambered condition in reptiles?​

Answer 1

Answer:

The reptile with a near “four-chambered heart” is the crocodile. This is due to evolutionary adaption in crocodiles.

Explanation:

• Reptiles like crocodiles and alligators “have a four-chambered heart” with “two auricles and two ventricles” and unique circulatory adaptations and These adaptations are to suit their amphibian nature.
• The two arteries supply blood to the ‘lungs’ and some other parts of body.
• This pumping of blood takes place usually during their submergence period.
• The blood moves from one chamber to another through the “foramen of Panizza”, which is a small hole present in the crocodile’s heart.

Answer 2

Answer: Crocodile

Explanation: reptiles are known for having three chambered heart but heart has two complete auricles but ventricles are incompletely partitioned .so heart is not perfectly four chambered except for crocodile as it has completely partitioned ventricles.so crocodile shows a near four chambered condition in reptiles
