swell as they fill with white and red cells caused by infection.
Spermatogonia are located at the periphery of the alveoli
forming a row, whereas a wide band of spermatocytes and spermatids is observed toward the alveoli
Transport of air along sheaths of pulmonic blood vessels from alveoli
to mediastinum: Clinical implications.
One protein helps build new alveoli
; the other stimulates alveoli
to expel carbon dioxide, Massaro says.
Oxygen molecules from the air you breathe pass easily through the walls of the alveoli
and into the tiny capillaries.
may allow air to track into the interstitium of the bronchopulmonary bundle and escape toward the mediastinum, producing a pneumomediastinum.
Professor Douglas Dockery, from Harvard School of Public Health, who co-led the study, said: 'They are so small that they can get past the normal defence mechanisms in the lungs and penetrate deeply into the air exchange regions, or alveoli
Alveolar Duct--The opening through which air passes between the respiratory bronchioles and the alveoli
Your bronchioles dead-end into tiny clumps of air sacs called alveoli
Bronchoalveolar lung carcinoma spreads along the alveoli
and bronchiolar surfaces, making it nearly impossible to resect.
posterior to the fourth are covered with matrix, but a natural mold of one of these alveoli
, visible in cross section on the posterior surface of the specimen, indicates that they were very small.
Infection begins when the bacilli reach the tiny air sacs of the lungs known as alveoli
, where they multiply within macrophages.
This tree-like system ends in tiny air sacs called alveoli
Many of the currently used terms for the components of the lung such as lobules, alveoli
, arteries, and veins come from these authors.
I also learned that nicotine is addictive in the particulate phase and the gas phase de livers many more poisons--carbon monoxide (which displaces needed oxygen from red blood cells), formaldehyde, ammonia, nitrogen oxides, benzene, acrolein, pyridine, and hydrogen cyanide, to name a few--directly into the lungs' bronchial airways and alveoli
(air sacs) and, thence, directly and quickly into the bloodstream.
