Background: The outflow tract of crocodilians resembles that of birds and mammals as
ventricular septation is complete. The arterial anatomy, however, presents with a pulmonary …

The functional and possible adaptive significance of non-avian reptiles' dual aortic arch
system and the ability of all non-avian reptiles to perform central vascular cardiac shunts …

There are large differences in the morphology of the vertebrate heart; from the fish heart with
its single atrium and single ventricle to the crocodilian, bird and mammalian hearts with two …

Background Cardiac outflow tract patterning and cell contribution are studied using an evo-
devo approach to reveal insight into the development of aorto-pulmonary septation. Results …

Blood pressures have been recorded in the heart along with pressures and flow in the aortic
arches of anaesthetized and awake alligators. Systemic blood pressures were significantly …

Among the vertebrates, crocodilians have the most complex anatomy of the heart and
outflow channels. Their cardiovascular anatomy may also be the most functionally …

Prolonged submergence imposes special demands on the cardiovascular system. Unlike
the situation in diving birds and mammals, crocodilians have the ability to shunt blood away …

In vertebrate embryos, cardiac precursor cells of the primary heart field are specified in the
lateral mesoderm. These cells converge at the ventral midline to form the linear heart tube …

Background The crocodilian heart is unique among reptiles with its four-chambered
structure and complete intracardiac separation of pulmonary and systemic blood flows and …

The heart of the African clawed frog has a double-inlet and single-outlet ventricle supporting
systemic and pulmonary circulations via a truncus, and a lifespan of 25–30 years. We sought …
