Expiration: breathing's other face.

Trade-offs in the Evolution of the Respiratory Apparatus of Chordates

TLDR
Compared with the kinetic bronchoalveolar mammalian lung, the avian system combines a large surface area and thin air–blood barrier of the constant volume lung with ease of inflation of the air sacs, resulting in energy-efficient gas exchange.

Breathing and locomotion: Comparative anatomy, morphology and function

Evolution and Functional Differentiation of the Diaphragm Muscle of Mammals.

TLDR
The DIAm pump evolved from the advantage afforded by more effective generation of both a negative Pth for ventilation of the lungs and a positive Pab for venous return of blood to the heart and expulsive behaviors such as airway clearance, defecation, micturition, and child birth.

Eye Movements in Frogs and Salamanders—Testing the Palatal Buccal Pump Hypothesis

TLDR
There is no experimental support for the idea of a palatal buccal pump in extinct temnospondyl amphibians, in contrast to earlier suggestions, and X-Ray Reconstruction of Moving Morphology is used to investigate eye movements during lung breathing and feeding in bullfrogs and axolotls.

Function of Intracoelomic Septa in Lung Ventilation of Amniotes: Lessons from Lizards*

TLDR
These septa provide plausible functional models that help to infer the evolution of mammalian and avian lung ventilatory systems, respectively.

Locomotor rib kinematics in two species of lizards and a new hypothesis for the evolution of aspiration breathing in amniotes

TLDR
Unilateral locomotor rib movements are remarkably similar to the bilateral pattern used for lung ventilation, suggesting a new hypothesis that rib motion during locomotion may have been an exaptation for the evolution of costal aspiration breathing in stem amniotes.

Lung ventilation during treadmill locomotion in a semi-aquatic turtle, Trachemys scripta.

TLDR
This study measured lung ventilation during treadmill locomotion in a semi-aquatic turtle, the red-eared slider, Trachemys scripta, and found no consistent evidence for phase coupling between breathing and locomotion indicating that sliders do not use locomotor movements to drive breathing.

Breathing with floating ribs: XROMM analysis of lung ventilation in savannah monitor lizards

TLDR
In savannah monitors, all dorsal ribs, both true and floating, contribute equally to ventilation, in contrast to green iguanas, where ventilation is dominated by the true ribs.

Scaling of axial muscle architecture in juvenile Alligator mississippiensis reveals an enhanced performance capacity of accessory breathing mechanisms

TLDR
The anatomy of the trunk muscles, their properties that determine muscle performance (mass, length and physiological cross‐sectional area [PCSA]) and their scaling in juvenile Alligator mississippiensis are described and investigated to support existing anecdotal evidence that crocodilians shift their breathing mechanics as they increase in size.

New perspectives on the evolution of lung ventilation mechanisms in vertebrates

TLDR
The discovery that several species of lizards use a buccal pump to augment costal aspiration during exercise, combined with the observation that a behavior known as “buccal oscillation” is found in all amniotes except for mammals, suggests that a reappraisal of the role of buCCal pumping in extant and extinct amniots is in order.

Lung ventilation in salamanders and the evolution of vertebrate air-breathing mechanisms

Abstract Functional analysis of lung ventilation in salamanders combined with historical analysis of respiratory pumps provides new perspectives on the evolution of breathing mechanisms in

Mechanics of lung ventilation in a post-metamorphic salamander, Ambystoma Tigrinum.

TLDR
Exhalation in adult tiger salamanders is active during aquatic gulping breaths, whereas exhalation appears to be passive during terrestrial breathing at rest, supported by previous findings that terrestrial frogs ventilate their lungs with small tidal volumes and exhale passively, whereas aquatic frogs and salamander use large tidal volumes And exhale actively.

Reconstructing the evolution of the respiratory apparatus in tetrapods

Mechanics of lung ventilation in a larval salamander Ambystoma tigrinum.

  • 1998
TLDR
Exhalation in larval tiger salamanders is active, powered by contraction of all four layers of lateral hypaxial musculature, and Electromyography indicates that the transverse abdominis (TA) muscle is active for the longest duration and shows the highest-amplitude activity, but the externally oblique superficialis, the external oblique profundus and the internal oblique also show consistent, low-level activity.

Mechanics of lung ventilation in a large aquatic salamander, siren lacertina

  • Brainerd

  • 1998
TLDR
Results indicate that the use of the TA for exhalation is a primitive character for salamander and support the hypothesis that the breathing mechanism of salamanders represents an intermediate step in evolution between a buccal pump and an aspiration pump.

TLDR
These septa provide plausible functional models that help to infer the evolution of mammalian and avian lung ventilatory systems, respectively.

The evolution of locomotor stamina in tetrapods: circumventing a mechanical constraint

TLDR
Tetrapod lineages that gave rise to modern ectotherms apparently retained the constraint, becoming either highly specialized for burst activity based on anaerobic metabolism or specialized in passive mechanisms of defense against predators.

Archosaurian respiration and the pelvic girdle aspiration breathing of crocodyliforms

TLDR
Re–examination of fossil archosaurs reveals that pubic rotation evolved in basal crocodyliforms and that pelvic girdle breathing is not a general archosaurian mechanism.

A functional analysis of the aquatic and aerial respiratory movements of an African lungfish, Protopterus aethiopicus, with reference to the evolution of the lung-ventilation mechanism in vertebrates.

  • B. Mcmahon
  • Environmental Science
    The Journal of experimental biology
  • 1969
TLDR
The evidence suggests that the air-breathing mechanism of the tetrapods was powered by a buccal force-pump mechanism which evolved directly from the aquatic system, and the evolution of a new mechanism for lung ventilation in the prototetrapods is considered unnecessary.
