Reptiles like turtle have three chambered heart with the exception of crocodile which has a four chambered heart.
Heart is an organ which is responsible to pump blood throughout the body of the organism.
Double circulation, just like humans is the characteristic of the crocodile's heart leading to a specific flow of blood into the atria and ventricles respectively. No mixing of blood occurs in this case.
Incomplete circulation, is the characteristic of the reptilian heart leading to a non-specific flow of blood into the atria and ventricles respectively. Mixing of blood occurs in this case.
