Final answer:
There are typically 10 bronchopulmonary segments in the right lung and 8-9 in the left lung, totaling 18-19 segments in both lungs.
Step-by-step explanation:
The number of bronchopulmonary segments in each lung is not uniform between the two. Typically, the right lung, which consists of three lobes — the superior, middle, and inferior lobes — has 10 bronchopulmonary segments. In contrast, the left lung comprises two lobes — the superior and inferior lobes — which house a total of approximately 8-9 bronchopulmonary segments. Hence, an individual generally has 18-19 bronchopulmonary segments. These segments are clinically significant as they can be surgically removed individually if affected by disease, since each segment has its own blood supply and airflow from tertiary bronchi.
