In amphibians, reptiles, birds and mammals, blood flow is directed to two circuits. One passes through the lungs and returns to the heart, called the pulmonary circulation. The other flows to the rest of the body and its entire organs. Brain (systemic circulation). Thus, amphibians have a dual circulation system consisting of two circuits. The whole body circuit circulates blood between the heart and the rest of the body, and the lung skin circuit circulates blood between the heart, lungs and skin. Click to see the full answer. The blood circulation of reptiles is double, closed and incomplete. It consists of two atria (connected by an opening called the Foramen de Panizza), a heart with ventricles, and a blood vessel. Reptiles are Saudis, Keronias, Opossums, and Crocodileans in that order. Image via schoolbag.info In that sense, the crocodile reptile circulatory system is closed, double and complete (Natural, 2013). The circulatory system of crocodile reptiles is said to be closed because the blood contained inside does not move outside the blood vessels.
