alveolar epithelium

The bacteria were introduced onto the apical surface of the alveolar epithelium.

As air is pulled into the lungs, alveolar epithelium and the coupled endothelium in the capillaries are stretched.

Other causes include shock, near-drowning, multiple transfusions and inhalation of irritants or toxic fumes that damage the alveolar epithelium.

It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, perivascular and perilymphatic tissues.

By contrast, the density of silver-grain deposits over airway and alveolar epithelium underlined by dense fibrosis was only slightly higher than the background density.

In normal gas exchange, carbon dioxide diffuses across the endothelium of the capillaries, the interstitial space, and across the alveolar epithelium; oxygen diffuses in the other direction.

In fetal lung, leptin is induced in the alveolar interstitial fibroblasts ("lipofibroblasts") by the action of PTHrP secreted by formative alveolar epithelium (endoderm) under moderate stretch.

The damage to the endothelium and the alveolar epithelium results in the creation of an open interface between the lung and the blood, facilitating the spread of micro-organisms from the lung systemically, stoking up a systemic inflammatory response.
