| Back | Structure: the right lung has two fissures 1. Oblique fissure lies in an obliquely oriented plane passing posterly from the level of the T2 spinous process to the 6th costal cartilage anteriorly. 2. Horizontal fissure lies in a horizontal plane extending from the 4th costal cartilage posteriorly to intersect with the oblique fissure. Function: separates the right lung into three lobes a) superior lobe - anterosuperior to the inferior lobe, includes the apex b) middle lobe - the lower part of the superior lobe, separated by the horizontal fissure c) inferior lobe - posterior-most and inferior-most lobe |
