Definition of albeola

(Richard F. McLaughlin, et al., "A study of the...)

The pulmonary_artery , in_addition to supplying the distal portion of the respiratory bronchiole , the alveolar duct , and the alveoli , continues on and directly supplies the thin pleura ( fig. 8 ) .

This vessel could be followed to the parenchyma where it directly provided bronchial arterial blood to the alveolar capillary_bed ( figs. 17 , 18 ) .

Also three other direct pathways of alveolar bronchial arterial supply were noted : via the pleura ; through the interlobular septa ; and along the terminal bronchiole ( figs. 14 , 17 , 18 , 19 ) .

For_example , the marked susceptibility of the monkey to respiratory infection might be related_to its delicate , long alveolar ducts and short , large bronchioles situated within a parenchyma entirely lacking in protective supportive tissue barriers such_as those found in types 1 , and 3 , .

The only area in which one might find major disagreement in this matter is in regard_to the alveolar distribution of the bronchial_arteries .
