Organ — Respiratory

Depending on an organism's habitat and metabolic needs, the form of the respiratory organ varies significantly: Respiratory Organ‐on‐a‐Chip for Disease Modeling

Respiratory organs are specialized biological structures designed to facilitate gas exchange—primarily the uptake of oxygen ( O2cap O sub 2 ) and the release of carbon dioxide ( CO2cap C cap O sub 2 respiratory organ

: Respiratory surfaces consist of incredibly thin, squamous epithelial cells. This "air-blood barrier" must be as thin as possible to allow for rapid diffusion. Depending on an organism's habitat and metabolic needs,

). While humans rely on lungs, the animal kingdom features a wide variety of respiratory systems adapted to diverse environments, from the deep ocean to high altitudes. Primary Features of Respiratory Organs respiratory organ
