A bronchopulmonary segment is a portion of lung supplied by a specific tertiary bronchus (also called a segmental bronchus) and arteries. These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment. The segments are separated from each other by layers of connective tissue. Each bronchopulmonary segment is a discrete anatomical and functional unit, and this separation means that a bronchopulmonary segment can be surgically removed without affecting the function of the others. There are 10 bronchopulmonary segments in the right lung: three in the superior lobe, two in the middle lobe, and five in the inferior lobe. Some of the segments may fuse in the left lung to form usually 8-9 segments (4–5 in the upper lobe and 4–5 in the lower lobe). Delineation of the bronchopulmonary segments was made by Dr. John Franklin Huber, Dr. Chevalier Jackson and Dr. Charles M. Norris at Temple University Hospital. ==Right lung== * Superior lobe * * apical segment * * posterior segment * * anterior segment * Middle lobe * * lateral segment * * medial segment * Inferior lobe * * superior segment * * medial-basal segment * * anterior-basal segment * * lateral-basal segment * * posterior-basal segment 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bronchopulmonary segment」の詳細全文を読む スポンサード リンク
