During the course of an anatomical study of specimens of emphysematous lungs evidence was found to suggest that the bronchial circulation might play a more important part in producing the disease picture than has been appreciated hitherto. Consequently we undertook a detailed investigation of the bronchial arteries and veins in both normal and diseased lungs.
Marchand et al. (1950) studied this question.
