They are located sparsely in these bronchioles, line the walls of the alveolar ducts, and are more numerous in the blind-ended alveolar sacs. [5] The acini are the basic units of respiration, with gas exchange taking place in all the alveoli present. [6] The alveolar membrane is the gas exchange surface, surrounded by a network of capillaries.
A further complication in the case of the alveolar glands may occur in the form of still smaller saccular diverticuli growing out from the main sacculi. The term "racemose gland" [2] is used to describe a "compound alveolar gland" or "compound acinar gland." [3] Branched alveolar glands are classified as follows:
Similarly, since the blood arriving in the alveolar capillaries has a partial pressure of CO 2 of also about 6 kPa (45 mmHg), whereas that of the alveolar air is 5.3 kPa (40 mmHg), there is a net movement of carbon dioxide out of the capillaries into the alveoli. The changes brought about by these net flows of individual gases into and out of ...

Collateral ventilation is a back-up system of alveolar ventilation that can bypass the normal route of airflow when airways are restricted or obstructed. The pathways involved include those between adjacent alveoli ( pores of Kohn ), between bronchioles and alveoli (canals of Lambert), and those between bronchioles (channels of Martin).

1. Ketogenic Diet. Cancer cells rely on glucose for energy to grow. The ketogenic diet is a way to provide an alternative energy source to normal cells in the dog's body while starving the cancer ...
Thus, it includes the alveolar ducts, sacs, and alveoli but not the respiratory bronchioles. [30] The unit described as the secondary pulmonary lobule is the lobule most referred to as the pulmonary lobule or respiratory lobule. [25]: 489 [31] This lobule is a discrete unit that is the smallest component of the lung that can be seen without aid ...
