Bronchial Tree Anatomy Quiz

Study Notes

Bronchial Tree Components

L Primary Bronchus: The main airway that branches off into the right and left lungs, resembling the trunk of a tree.
Secondary Bronchus: The primary bronchus divides into secondary bronchi, each supplying a lobe of the lung. The right lung has three lobes, thus three secondary bronchi; the left lung has two lobes.
Tertiary Bronchi: Further divisions of the secondary bronchi that branch into smaller airways, supplying bronchopulmonary segments within each lobe.

Alveoli and Terminal Structures

Alveoli in Pulmonary Lobule: Microscopic air sacs where gas exchange occurs, clustered in lobules and surrounded by capillaries for efficient oxygen and carbon dioxide transfer.
Bronchioles: Smaller branches that lead from tertiary bronchi, with a diameter of less than 1 mm; they contain smooth muscle to regulate airflow and lack cartilage.
Terminal Bronchi: The last segment of conducting airways, leading into the respiratory zone. They do not participate in gas exchange but serve as passageways for air.
Respiratory Bronchiole: Transitional structures between conducting airways and sites of gas exchange, featuring small alveoli along their walls for initial gas exchange.
Bronchopulmonary Segment: Specific sections of lung lobes comprised of tertiary bronchi and surrounding tissue; each segment can be isolated for clinical procedures (e.g., surgery) due to its discrete blood supply and drainage.
