Study Notes
Bronchial Tree Components
-
Larynx:
- Also known as the voice box, located between the pharynx and trachea.
- Functions in sound production, protection of the trachea against food aspiration, and air passage.
-
Trachea:
- A tubular structure also known as the windpipe, connecting the larynx to the bronchi.
- Composed of C-shaped cartilage rings that prevent collapse and allow flexibility.
-
Tracheal Cartilage:
- Supportive cartilage surrounding the trachea.
- Maintains trachea shape, allowing air to pass freely while preventing obstruction during inhalation and exhalation.
-
Primary Bronchi:
- The two main branches that emerge from the trachea, leading into each lung (right and left primary bronchi).
- Responsible for directing airflow into the lungs.
-
Secondary Bronchi:
- Also known as lobar bronchi, these branches stem from the primary bronchi.
- Each primary bronchus divides into secondary bronchi that correspond to the lung lobes (three on the right, two on the left).
-
Tertiary Bronchi:
- Also referred to as segmental bronchi, further branches of secondary bronchi.
- Supply air to specific segments of the lung lobes, facilitating efficient gas exchange within the lungs.
