Alveolar macrophages (AMs) originate from monocytes present in the yolk sac or fetal liver and later migrate to the lungs ... which results in the deposition of surfactant in the alveoli. Figure 3 ...

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose ...

Diseases that can affect these airways include: Your airways branch into tiny tubes (bronchioles) that end in clusters of air sacs called alveoli. These air sacs make up most of your lung tissue.

Terminal air spaces and alveoli within ... walls of terminal sacs. Initial low secondary crests were observed as early as P1, as was reported previously (18). Numbers of alveolar secondary crests ...

Damage from COPD sometimes keeps the tiny air sacs in your lungs, called alveoli, from getting enough oxygen. That's called alveolar hypoxia. This kind of hypoxia can start a chain reaction that ...

Doctors are issuing urgent warnings about a common antibiotic after Emmie Bellucci, 12, of Texas fell mysteriously ill last year with respiratory failure shortly after taking her second course of it.

Airspace dimensions and extra-alveolar vessel diameters were measured. Lung function measurements and pulmonary CT scans were obtained in all participants. Conclusions This is the first FCFM study to ...
