Abstract

Studies demonstrate that the heart rate is maintained virtually constant during most of the embryonic development of reptiles, despite the continuous increase in oxygen demand by the developing embryo. However, information about the cardiovascular adjustments that allows the appropriate oxygen delivery to embryonic tissues are scarce in reptiles, in contrast to avian models. In this way, this work aims to measure variables such metabolism, heart rate, cardiac volume and oxygen carrying capacity by blood of embryos of the chelonian specie Chelydra serpentina to elucidate the integrative mechanism that maintains the relation between the oxygen consumption and delivery along the development.
