	Blue Histology - Respiratory System
		Cilia in the epithelium of the olfactory region arise from olfactory cells.
		Depending on the extent of abrasive forces on the epithelium, the pharynx is either lined with respiratory epithelium (nasopharynx or epipharynx) or with a stratified squamous epithelium (oropharynx or meso- and hypopharynx), which also covers the surfaces of the oral cavity and the oesophagus.
		The histological structure of the epithelium and the underlying connective tissue of the bronchi corresponds largely to that of the trachea and the main bronchi.

	RESPIRATORY SYSTEM
		The role of the respiratory passages is not only to conduct the inhaled air to the terminal respiratory units for gaseous exchange with the blood, but also to provide the adequate medium for alterations in the physical composition of the air, minimizing the environmental insult to the terminal units of the lung.
		This lesion that affects the upper respiratory tract is considered a form of the peripheral T cell (non Hodgkin) lymphoma, a neoplasm of the natural killer cells.
		There are three distinct varieties of papillary lesions that may affect the upper respiratory passages, all the lesions arising from the lining epithelium of the area, the nasal cavities are affected in 20% of the cases, the paranasal sinuses in 40% of the cases and both in 40% of the cases.

	Respiratory epithelium - Wikipedia, the free encyclopedia
		Respiratory epithelium is a type of epithelium found lining the upper and lower respiratory tracts, where it serves to moisten and protect the airways.
		Respiratory epithelium is more specifically known as ciliated pseudostratified columnar epithelium due to the arrangement of the columnar epithelial cells; the nuclei are not aligned in the same plane and make it appear as though several layers of cells are present.
		The cilia of the respiratory epithelium beat in a concerted effort to move secreted mucus containing trapped foreign particles towards the oropharynx for either expectoration or swallowing to the stomach where the acidic pH helps to neutralize foreign material and micro-organisms.

		The mucosal surface of the rest of the conducting portion is lined by respiratory epithelium, except the true vocal fold [Mac] [WinHome] (vocal cord or vocal ligament) in the larynx (W pg 237, 12.5).
		The stratified epithelium serves to protect the vocal cords from abrasion caused by vibrations of the true vocal folds during phonation.
		Beneath the epithelium, note the region which corresponds to the basement membrane we looked at with the light microscope (this is a good illustration of why "basal lamina" and "basement membrane" are not synonymous).

		Alveolitis, as historically defined, cannot suffice as an explanation for the characteristic pattern of fibrosis and disordered lung architecture that define usual interstitial pneumonia (UIP), the morphologic counterpart of idiopathic pulmonary fibrosis (IPF).
		Following epithelial injury, surviving and regenerating respiratory epithelium contributes to abnormal antifibrinolytic activity at sites of injury and also elaborates various fibrogenic cytokines/growth factors important in recruitment and phenotypic modulation of fibroblasts and myofibroblasts (2, 7).
		Furthermore, immunoreactivity for surfactant associated protein A was limited to hyperplastic epithelium associated with fibroblast foci in UIP/IPF, suggesting that pneumocytes are the primary players in UIP/IPF while bronchiolar epithelium or more primitive stem cells participate in cryptogenic organizing pneumonia.
