Host Defense in Pulmonary Alveoli
Annual Review of Physiology, 1992,and alveolar), airway reflexes (cough and sneeze), a mucociliary escalator covering most of the airways, and specialized cell-mediated defenses (phagocytic and non-phagocytic). Lung infections (pneumonias) are frequently precipitated by the failure of one or more of these mechanisms.

Ultrastructure of Pulmonary Alveoli of the Calf
American Journal of Veterinary Research, 1974SUMMARY The ultrastructural characteristics of lung of the normal calf were basically similar to those described in other mammals. The alveolar septums were comprised of an epithelial lining resting on a relatively thin basal lamina overlying a varied thickness of connective tissue which surrounded the capillaries.

Ultrastructural evidence for the innervation of human pulmonary alveoli
Experientia, 1980Electron Microscopic observations of the biopsied human pulmonary alveoli showed the occurrence of unmyelinated axons in the interstitium near the type I pneumocytes. These axons very likely have sensory functions.

AN IMPROVED MATHEMATICAL MODEL OF HYDRODYNAMICAL SELF-CLEANSING OF PULMONARY ALVEOLI
The Annals of Occupational Hygiene, 1993In the present paper we postulate a hydrodynamical mechanism of pulmonary alveoli cleansing and explain the role of the lung surfactant system in this phenomenon. Then a new, significantly refined mathematical model of the dynamics of the layer lining alveoli is derived and tested numerically in order to check theoretically whether the mechanism ...

Dust elimination from pulmonary alveoli
Environmental Research, 1980Abstract Some alveolar macrophages that engulf asbestos particles move through alveolar walls and spaces to the larger bronchioles. They pass through the bronchiolar wall to reach the lumen where they are elevated by cilia and pass out of the lung.

Ultrastructure of pulmonary alveoli and macrophages in experimental Legionnaires' disease
The Journal of Pathology, 1983AbstractGuinea pigs, rhesus monkeys and marmosets infected with Legionella pneumophila in small particle aerosols developed an acute fibrinopurulent bronchopneumonia. Changes from 24 hr included exudation into alveoli of protein‐rich, often fibrinous fluid and many polymorphonuclear leucocytes (PMN) and macrophages.

Translocation of Particles from Pulmonary Alveoli into the Interstitium*
Journal of Aerosol Medicine, 1992ABSTRACT There is evidence that particulate matter deposited in the alveoli during inhalation can be translocated from the alveoli into the pulmonary interstitium. The translocated particles can stay in the interstitium or they can be further translocated into the lymphatics or possibly into the blood. We have evidence that ultrafine particles (∼20 nm)

Postnatal development of pulmonary alveoli: modulation in rats by thyroid hormones
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1986We studied the effect of thyroid hormones on the postnatal development of the gas exchange region of rat lungs. Treatment with triiodothyronine (T3, 0.1 microgram . g body wt-1 . day-1) accelerated the increase of the surface-to-volume ratio (S/V) and surface area (Sa) and decrease of the mean chord length (Lm) of the gas exchange structures of pups ...

Innervation of pulmonary alveoli of the mouse lung: An electron microscopic study
American Journal of Anatomy, 1972AbstractThe nerve supply to the alveolar ducts and alveoli of mouse lungs was studied with the electron microscope. In the alveolar ducts, nerve bundles consisting of as many as nine unmyelinated axons surrounded by connective tissue fibers were usually located in the interstitium surrounding the openings of the alveoli.
