: Further divisions that supply smaller segments of the lungs.
: The trachea divides into the right main bronchus (shorter and wider) and the left main bronchus (longer and narrower). bronchial tube
The bronchial tubes begin where the trachea splits (bifurcates) into two primary paths: : Further divisions that supply smaller segments of
: These branch off the main bronchi to supply the specific lobes of the lungs (three on the right, two on the left). (or bronchi) are the large air passages that
(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
The tubes are composed of sturdy but flexible and smooth muscle . As the tubes get smaller, the amount of cartilage decreases while smooth muscle increases, allowing the airways to change diameter to regulate airflow. Key Functions Bronchiectasis usually the result of damage to airways
: The smallest branches that eventually lead to alveoli , the microscopic air sacs where gas exchange occurs.
