Right upper lobe apical segment

Last revised by Yahya Baba on 31 Dec 2022

The right upper lobe apical segment (segment 1) is one of the three bronchopulmonary segments of the right upper lobe. It is the most apical of the segments in the right upper lobe and the right lung.

Together with the posterior segment, it is analogous to the left upper lobe apicoposterior segment and occupies the apical zone of the frontal chest radiograph.
