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.

However, we believed that posterior intestine was the main section for gas exchange, i.e., 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.
MP begins to propagate on the respiratory surface of the ciliated epithelium, thereby inducing various cytokines [10].
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).
The harmonic mean thickness of the airhemolymph barrier was 0.14 [+ or -] 0.03 pm, the respiratory surface density was 122.99 [+ or -] 35.84 [mm.sup.-1], and the book lung volume ranged from 12.2 to 37.5 [mm.sup.3].
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. The functional role of ambital podia is more ambiguous; however, they are longer and are extended at a lower strain rate than other podial types.
Some of these modifications include: heart size, hemoglobin concentration, capillary density, erythrocyte size and changes in respiratory surfaces (Bouverot, 1985; Ruiz et al., 1989; Monge & Leon-Velarde, 1991; Weber, 1995; Samaja et al., 2003; Nikinmaa, 2013).
Respiratory surfaces are relatively smaller in larger organisms (lower surface area to volume ratio).
The new works incorporate bespoke textiles to evoke the feel and function of our respiratory surfaces. The 'Lung Dresses' will raise the view that we take our lungs for granted and are unable to see the effects of smoke or particles that we inhale until it is too late.
"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.
