respiratory surface

respiratory surface

a special area that is developed in order to satisfy the requirements for gaseous exchange in larger organisms. Examples include external gills, internal gills, lungs, and the insect tracheae. The surfaces are thin and moist with a differential gradient maintained between the air/water and the internal tissues.

the gas exchange occurred in a few microvilli in the extended ultrathin cytoplasmic lamella, indicating that microvilli are not directly related to the increased respiratory surface area but mainly plays a role in accessory digestion.
The surfactants secreted by lamellar bodies are beneficial for maintaining the stability of the entire respiratory surface and for performing their normal functions.
Microscopical examination using hematoxylin and eosin (H&E) stain showed a ciliated respiratory surface epithelium having bland nuclear chromatin with numerous glandular spaces lined by the same type of epithelium underneath it.
All such damages make gills and accessory respiratory organs less functioning by reducing the respiratory surface (Eissa, 2002).
In this study we hypothesized that Grammostola rosea Walckenaer 1837, an active predator of large size which depends entirely on its two paired book lungs, has a low energy strategy based on large respiratory surface area and a thin air-hemolymph barrier.
Histology showed that lung exposure to a mixture of 14-nm particles, which had only minor effects themselves, and LPS led to recruitment of neutrophils in the parenchyma, the actual respiratory surface of the lung.
We found that oral podia, which are used primarily for locomotion and adhesion, are stronger and thicker than aboral podia, which are used primarily for capturing drift material and as a respiratory surface.
Respiratory surfaces are relatively smaller in larger organisms (lower surface area to volume ratio).
Cockroaches lose water across their respiratory surfaces when they breathe, so taking shorter breaths in dry conditions reduces the amount of water they will lose," said Schimpf.
Examples include cleaning of respiratory surfaces in both terrestrial vertebrates and aquatic invertebrates, as well as suspension-feeding in aquatic invertebrates.
