Life originated in anoxia, but many organisms came to depend upon oxygen for survival,
independently evolving diverse respiratory systems for acquiring oxygen from the …

The avian respiratory apparatus is separated into a gas exchanger (the lung) and ventilators
(the air sacs). Synchronized bellows-like movements of the cranial and caudal air sacs …

Background Type IV collagen is the main component of the basement membrane that gives
strength to the blood–gas barrier (BGB). In mammals, the formation of a mature BGB occurs …

The current study was designed to give complete histo‐and immunohistochemical features
of the parabronchial epithelium of domestic fowl's (Gallus gallus domesticus) lung with …

Among the extant air‐breathing vertebrates, the avian respiratory system is structurally the
most complex and functionally the most efficient gas exchanger. Having been investigated …

Within animals, oxygen exchange occurs within vascular transport networks containing
potentially billions of microvessels that are distributed throughout the body. By comparison …

The anatomy and volume of the penguin respiratory system contribute significantly to
pulmonary baroprotection, the body O2 store, buoyancy and hence the overall diving …

From a biological point of view, casting refers to filling of anatomical and/or pathological
spaces with extraneous material that reproduces a three-dimensional replica of the space …

During vertebrate development, the lung inaugurates as an endodermal bud from the
primitive foregut. Dichotomous subdivision of the bud results in arborizing airways that form …

This book encapsulates over three decades of the author's work on comparative functional
respiratory morphology. It provides insights into the mechanism (s) by which respiratory …
