Anatomy and Physiology of the Reptile Renal System Veterinary Clinics of North America: Exotic Animal Practice, Vol. Crocodiles may not cry real tears, but they do have special hearts.

Pressure gradients from ventricle to aorta during systole are very small. However, the topography of the intrapulmonary bronchus and of the first bronchi is similar in birds and crocodilians.

Crocodile hearts A crocodile's special heart may help it digest large, bony meals. The circulatory system helps to keep homeostasis in the kidneys. Alligator forerunners and relatives have been around for a very long time. Related Questions. no it has a closed circulatory system and a 4 chambered heart .

Again similar to humans the crocodile has a four-chambered heart and a double circulation system. The complexity enables the cardiovascular system to divert oxygenated blood to the brain to keep it activated (thus keeping the animal alive), enabling the alligator to hold its breath for long periods, and even to practically "shut down" its brain during hibernation in the colder parts of its natural range.
