A comprehensive 3D model of the Bronchial Anatomy is now available, featuring a detailed color map and bump maps. This model is optimized for use in 3D medical animation and presentation projects. The model has been converted into various formats, including 3ds, max, maya, and lightwave, allowing it to be easily imported into any 3D software package. A bronchus is a vital airway passage within the respiratory tract that directs air into the lungs. No gas exchange occurs in this part of the lungs. The trachea branches off into two primary bronchi, the left and right mainstem bronchi, at the level of the sternal angle known as the carina. The right main bronchus is wider, shorter, and more vertical than its counterpart on the left side. The right main bronchus further divides into three lobar bronchi, while the left main bronchus splits into two. These lobar bronchi then subdivide into tertiary bronchi, also referred to as segmental bronchi, each of which supplies a distinct bronchopulmonary segment. A bronchopulmonary segment is a self-contained division of the lung, isolated from other segments by a connective tissue septum. This unique characteristic enables surgeons to remove a bronchopulmonary segment without impacting adjacent areas. Each lung contains ten such segments; however, due to anatomical development, several segmental bronchi in the left lung fuse together, resulting in eight distinct segments. The segmental bronchi then give rise to numerous primary bronchioles, which further divide into terminal bronchioles. These terminal bronchioles eventually lead to respiratory bronchioles, completing the intricate branching structure of the Bronchial Anatomy model.
