[Lymph flow from the lungs in conditions of normal capillary permeability]

The source of the lung lymph formation was studied in 8 experiments on dogs and in 30 experiments on isolated lungs. The former revealed the effect of bronchial vessels ligature upon the lung lymph outflow, the latter series aided to trace the lymph flow in perfusion of the lung artery's vessels and bronchial vessels. The section of bronchial vessels decreased by 4-6 times the lymph outflow. No lymph outflow was observed in perfusion of isolated lungs whereas in perfusion of bronchial vessels the lymph flow was directly related to the pressure level in the bronchial vessels. These vessels are concluded to be of the primary importance for the lung lymph formation.
