Collateral Pulmonary Respiration of Van Allen
process was impaired by inflammation.3,9 These observations were confirmed by means of gas analysis by Lindskog and Van Allen.A Collateral respiration was also demonstrated in relation to experimental segmental emphysema produced by valvular bronchial obstruction. Lobar emphysema followed valvular obstruction of lobar bronchi, but no emphysema resulted from this type of obstruction in the prima...
متن کاملCollateral Respiration Literature
During the course of some experimental work on the pathogenesis of obstructive pulmonary atelectasis we have noted a consistent occurrence of certain forms of behavior which suggests that the lobules composing single lobes of the lungs are connected collaterally with each other. Thus, after the bronchus of one lobule has been obstructed, that lobule appears to receive air from, and to give air ...
متن کاملGaseous Interchange Between Adjacent Lung Lobules
It is desired to make a preliminary report of certain experimental evidence that respiratory and other gases may enter one lobule from another in the lung without resort to known anatomical passageways. This was found in vivo and in vitro in work with dogs. In vitro observations. A single lung lobe, freshly secured, was prepared by dissection at the hilus and isolation of the stem bronchus and ...
متن کاملMitochondrial transfer between cells can rescue aerobic respiration.
Current theory indicates that mitochondria were obtained 1.5 billion years ago from an ancient prokaryote. The mitochondria provided the capacity for aerobic respiration, the creation of the eukaryotic cell, and eventually complex multicellular organisms. Recent reports have found that mitochondria play essential roles in aging and determining lifespan. A variety of heritable and acquired disea...
متن کاملCollateral Respiration in the Normal and Diseased Lung *
Until 1930 the pulmonary lobule was generally considered to be anatomically and functionally an end structure, to which the only access of air lay in the direct bronchial route. All available anatomical data from such pioneer workers as Joseph Marshall Flint, Macklin, and William Snow Miller argued against the possibility of air passing collaterally from one pulmonary lobule to an adjacent one ...
