Question

Quizplus · Accepted Answer

Bronchopulmonary segments are defined as the portion of lung tissue that is supplied by a single tertiary bronchus, along with its branches. This definition is based on the anatomical and functional divisions of the lung, rather than arbitrary subdivisions or ease of removal during surgery. The segments are separated by connective tissue septa, and each segment has its own blood supply and lymphatic drainage. Understanding the bronchopulmonary segments is important in diagnosing and treating lung diseases, as well as planning and performing surgical procedures on the lung.
