Bronchial circulation has three components: a systemic arterial component represented by the bronchial arteries; a pulmonary venous component represented by the pulmonary veins; and a systemic venous component represented by the bronchial veins. We have used vascular casting, microscope dissection coupled with tracers and light microscopy to define the detailed anatomy of the pulmonary venous compartment of the bronchial circulation. We have found that the extrapulmonary drainage territory of the pulmonary veins correlate with the forming pattern of the right superior pulmonary vein. In the case of a large apical venous trunk, pulmonary veins drain the venous blood of the main bronchia, terminal portion of the trachea and of the tracheobronchial lymph nodes. In the case of the systemic venous drainage of the extrapulmonary airways, we constantly found a pulmonary component which drains the venous blood from the subcarinal lymph nodes and the medial side of the main bronchia.
以支气管动脉为代表的体循环动脉成分；以肺静脉为代表的肺静脉成分；以及以支气管静脉为代表的体循环静脉成分。我们运用血管铸型、结合示踪剂的显微镜解剖以及光学显微镜来明确支气管循环中肺静脉部分的详细解剖结构。我们发现肺静脉的肺外引流区域与右上肺静脉的形成模式相关。在存在粗大尖段静脉干的情况下，肺静脉引流主支气管、气管末端以及气管支气管淋巴结的静脉血。在肺外气道的体循环静脉引流情况中，我们始终发现有一个肺成分，它引流隆突下淋巴结和主支气管内侧的静脉血。
