Cardiovascular System in Reptiles
Original language description
Reptiles possess an essential role in the evolution of mammals and birds, and their position in the phylogeny of amniotic vertebrates makes them ideal models in evolutionary studies, especially in comparative anatomy, development, or physiology. However, the studies on thereptilian cardiovascular system are few when compared with studies of other ectotherms (zebrafish, Xenopus, Axolotl) or endotherms such as chicks or mice. Nevertheless, reptiles are very important models because they do show more variation in heart morphology than any other vertebrate group. The reptilian heart takes a specific position among vertebrate cardiovascular systems with different ventricular septation levels from nonseptated (e.g., leopard geckos), almost septated (pythons and monitor lizards), to fully septated ventricle (crocodylians) as well as the number of the aortic arches - the right aortic and the left aortic arches are unique among vertebrates at all. The cardiovascular development in extant reptilian lineages also differs, but at the same time, similarities are observed across the vertebrate phylogenetic tree. This is particularly true for Amniota, where analogous structures are found between mammals and sauropsids (e.g., gene expressions in the ventricular septum/septa). Moreover, thanks to specific reptilian heart morphology, the mixing of oxygenated and deoxygenated blood results in hemodynamically specific blood flowing - the cardiac shunts, which are detrimental for endothermic vertebrates. This chapter summarizes up-to-date research on the cardiovascular system, its development, and hemodynamics in reptiles, with a focus on specific features in all extant reptilian major lineages: Lepidosauria (Sphenodontia and Squamata), Archelosauria (Chelonia and Archosauria), and Archosauria (Crocodylia and Aves).
