Involuntarily controlled muscle that regulates airflow by contracting (bronchoconstriction) or relaxing (bronchodilation).
The first branch into the right and left lungs. The right main bronchus is shorter, wider, and more vertical than the left main bronchus , making it a more common site for aspirated foreign objects. bronchus
Acts as a passageway for air moving from the trachea to the smaller bronchioles and eventually the alveoli for gas exchange. Acts as a passageway for air moving from
Further divisions that supply specific bronchopulmonary segments. Histological Layers: These tubes are part of the conducting zone
The (plural: bronchi ) is a critical, large airway tube that branches from the trachea (windpipe) to deliver air into the lungs. These tubes are part of the conducting zone of the respiratory system, serving as the main distribution network for oxygen while filtering and moisturizing inhaled air. Anatomy and Structure
The bronchial tree starts where the trachea bifurcates at a point called the . Generations of Branching:
The "mucociliary escalator" uses rhythmic ciliary motion to push mucus and trapped particles upward toward the pharynx for clearance.
