Name the reptilian animals which have incompletely divided 4 chambered heart.
Answer: Lizard.
The heart consists of four chambers arranged in a linear sequence. Types of reptilian hearts: lizard, snake, crocodile, and turtle. One aspect of the amphibian system is that the blood leaving the heart for the body is only partially aerated; part of it is made up of deoxygenated blood returned from the body. Lizard is a reptile.
All the reptilian animals have a three-chambered heart which consists of two atria and one ventricle which is partially divided.
This even leads to mixing of oxygenated and deoxygenated blood.
Crocodiles are the only reptilian animals which have a four-chambered heart and completely divided ventricles like other birds and mammals.
This is an unusual character among the present surviving reptiles.
