The unidirectional airflow patterns in the lungs of birds have long been considered a unique and specialized trait associated with the oxygen demands of flying, their endothermic metabolism and unusual pulmonary architecture. However, the discovery of similar flow patterns in the lungs of crocodilians indicates that this character is probably ancestral for all archosaurs—the group that includes extant birds and crocodilians as well as their extinct relatives, such as pterosaurs and dinosaurs… Expand
Unidirectional pulmonary airflow in vertebrates: a review of structure, function, and evolution
TLDR
The presence of unidirectional airflow in non-volant ectotherms voids the traditional hypothesis that this trait evolved to supply the high aerobic demands of flight and endothermy, and there is a need for new scenarios in the understanding of lung evolution. Expand
Pulmonary Transformations of Vertebrates
TLDR
The discovery of unidirectional airflow in crocodilians and lizards indicates that several inveterate hypotheses for the selective drivers of this trait cannot be correct, and opens an uncharted area for research into selective underpinning of unirrigated airflow. Expand
New insight into the evolution of the vertebrate respiratory system and the discovery of unidirectional airflow in iguana lungs
TLDR
It is shown that unidirectional flow is present in the lungs of the green iguana, an ectothermic animal with low aerobic capacity, no intrapulmonary bronchus, and no intercameral perforations, which indicates a transformation in understanding of the evolution of the vertebrate respiratory system is needed.

Computational Fluid Dynamics Reveals a Unique Net Unidirectional Pattern of Pulmonary Airflow in the Savannah Monitor Lizard (Varanus exanthematicus)
TLDR
The results indicate that the lung of the savannah monitor contains a unique net unidirectional flow, where the overall flow scheme is similar during expiration and late inspiration, but dissimilar during early inspiration. Expand
Unidirectional flow in lizard lungs: a paradigm shift in our understanding of lung evolution in Diapsida.
TLDR
Recent visualizations and measurements of flow in the lungs of monitor and iguanid lizards show a bird-like pattern of unidirectional flow in these lineages, much older than previously believed and advantageous to the low-energy lifestyles typical of ectothermic animals. Expand
Respiratory evolution in archosaurs
TLDR
Key events in archosaur evolution where respiratory physiology likely played a major role are highlighted, such as their radiation at a time of relative hypoxia following the Permo-Triassic mass extinction, and their evolution of elevated metabolic rates. Expand
Robust Unidirectional Airflow through Avian Lungs: New Insights from a Piecewise Linear Mathematical Model
TLDR
A novel mathematical model of the airflow in the avian respiratory system that can produce unidirectional flow is constructed which is robust to changes in model parameters, breathing frequency and breathing amplitude and provides additional novel insights. Expand
Anatomy, ontogeny, and evolution of the archosaurian respiratory system: A case study on Alligator mississippiensis and Struthio camelus
TLDR
3D digital models and CT scan data demonstrate that the pulmonary diverticula pneumatize the axial skeleton of the ostrich directly from the gas‐exchanging pulmonary tissues instead of the air sacs, suggesting that certain structural aspects of the bronchial tree are likely conserved across Archosauria. Expand
XROMM kinematics of ventilation in wild turkeys (Meleagris gallopavo)
TLDR
XROMM analysis shows that the ribs in birds move in a constrained, predictable way during breathing, which is important for modelling the evolution of avian ventilation and respiratory physiology. Expand
Heart development in the lizards (Varanidae) with the greatest extent of ventricular septation
TLDR
It is concluded that current concepts of ventricular septum formation apply well to the monitor septa and that there is evolutionary conservation of Ventricular sePTum formation among amniote vertebrates. Expand

TLDR
The data indicate that the aspects of the crocodilian bronchial tree that maintain the aerodynamic valves and thus generate unidirectional airflow, are ancestral for Archosauria. Expand
Unidirectional Airflow in the Lungs of Alligators
TLDR
It is shown that air flows unidirectionally through parabronchi in the lungs of the American alligator, an amphibious ectotherm without air sacs, which suggests that this pattern dates back to the basal archosaurs of the Triassic and may have been present in their nondinosaur descendants (phytosaurs, aetosaurs, rauisuchians, crocodylomorphs, and pterosaurs) as well as in dinosaurs.

TLDR
The alveolar lung evolved in the late Paleozoic, when high levels of atmospheric oxygen relaxed selection for a thin blood‐gas barrier within the lung; and unidirectional flow originated in the ectothermic ancestral archosaur, the forerunner of birds and crocodilians, to enable the heart to circulate pulmonary gases during apnea.

TLDR
Interestingly, despite remarkable morphological heterogeneity in the gas exchangers of extant vertebrates at maturity, the processes involved in their formation and development are very similar and Transformation of one lung type to another is clearly conceivable, especially at lower levels of specialization.

Comparison of the midinflation distance between inflation and deflation curves on standard volume--pressure diagrams indicates hysteresis may have an intrapul pulmonary component related to the degree of lung partitioning and an extrapulmonary component, attributable to forces hindering the free movement of the lung in the body cavity.

TLDR
I make a case that a firm (rigid) rib cage, a lung tightly held by the ribs and the horizontal septum, a Lung directly attached to the trunk, specially formed and compactly arranged parabronchi, intertwined atrial muscles, and tightly set air capillary and blood capillaries form an integrated hierarchy of discrete network system of tension and compression, a tensegrity (tensional integrity) array.

Contribution of gular pumping to lung ventilation in monitor lizards.
TLDR
Evidence presented here shows that, during locomotion, varanids use a positive pressure gular pump to assist lung ventilation, which supports the prediction that the axial constraint may be found in other tetrapods that breathe by costal aspiration and locomote with a lateral undulatory gait.
