The epiglottis opens to direct air into the respiratory pathway.
activation of the complement via the alternative pathway
All organs of the respiratory pathway are important in delivering oxygen. These include the pharynx, trachea, and lungs.

Of or pertaining to respiration; serving for respiration; as, the respiratory organs; respiratory nerves; the respiratory function; respiratory changes.
A non-genomic pathway is a signaling pathway that does not involve changes in gene expression. Instead, it typically involves rapid responses to extracellular signals, such as changes in ion fluxes or activation of kinase cascades, leading to rapid cellular responses. This pathway is independent of gene transcription and translation.
the respiratory system and the digestive system share the Pharynx. The Respiratory system contains the eppiglottis, which keeps food going down the esophogus instead of the trachea

The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
C3 plants refer to a type of plant that uses the C3 carbon fixation pathway during photosynthesis. This pathway is less efficient in hot and arid conditions compared to the C4 pathway used by C4 plants.

The respiratory system responds to changes primarily at the levels of the lungs, alveoli, and the central nervous system. Chemoreceptors in the brainstem and peripheral arteries detect changes in carbon dioxide and oxygen levels, triggering adjustments in breathing rate and depth. Additionally, the alveoli respond to changes in gas concentrations by facilitating gas exchange, while the lungs can adjust airflow and resistance through bronchoconstriction or bronchodilation. Together, these mechanisms help maintain homeostasis in the body's respiratory function.
