Stretching of alveoli during lung inflation is the main trigger for surfactant secretion.

The rapid crescendo of pain as her lungs expanded and her alveoli exploded.

Plugged alveoli attenuate the rays, and so appear on film as white patches.

Between them, the lungs have somewhere in the neighborhood of six hundred million alveoli.

Volatile substances can be released via alveoli, bronchial mucosa or from the upper airways.

The numbers of alveoli were reduced and the walls thickened.

The lungs - with 300 million alveoli - inhale and exhale just like flesh-and-blood ones.

However, as the infused liquid cleared, the alveoli reappeared and their diameters could be quantified.

Trace air from the outside atmosphere into the alveoli.

Additionally, emphysema tissue damage was observed in OVA-exposed alveoli.

Epithelial cells within these alveoli had distinct, centrally located nuclei and contained intracellular lipid droplets.

Few particles were counted at midpoints between bifurcations, and particles rarely were observed within alveoli.

Anthrax spores kill by producing lethal toxins that eventually rupture the alveoli in the lungs.

Yet, the molecular mechanisms how mechanical distension of alveoli results in surfactant secretion are still elusive.

Secretion of pulmonary surfactant in the alveoli of the lungs is essential to maintain lung function.

Gas exchange in the lung takes place via the air-blood barrier in the septal walls of alveoli.
