Tube: Bronchial

: These branch off the main bronchi to supply the specific lobes of the lungs (three on the right, two on the left).

: The smallest branches that eventually lead to alveoli , the microscopic air sacs where gas exchange occurs. bronchial tube

: The trachea divides into the right main bronchus (shorter and wider) and the left main bronchus (longer and narrower). : These branch off the main bronchi to

: Further divisions that supply smaller segments of the lungs. bronchial tube

(or bronchi) are the large air passages that connect the windpipe (trachea) to the lungs. They function as the main delivery system for air, branching out into a complex "bronchial tree" that ensures oxygen reaches the deep tissues of the lungs. Anatomy and Structure
