Respiratory system histology addresses the tissue-level organization of the airway, from the nasal cavity to the alveoli, and how specialized epithelial and structural components accomplish conditioning of inspired air (warming, moistening, cleaning), gas exchange, olfaction, phonation, and immune defense. The domain sits within human histology/anatomy, relating microscopic tissue architecture to macroscopic respiratory function, with particular emphasis on the differentiation of airway epithelium along the respiratory tree and the specialized alveolar-capillary interface where gas exchange occurs.
