Bronchus (2025-2027)

Acts as a passageway for air moving from the trachea to the smaller bronchioles and eventually the alveoli for gas exchange.

The bronchial tree starts where the trachea bifurcates at a point called the . Generations of Branching:

Further divisions that supply specific bronchopulmonary segments. Histological Layers: bronchus

These supply each lobe of the lung (three on the right, two on the left).

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.

Moistens and warms air as it enters the body to prevent damage to delicate lung tissues. Common Clinical Conditions Bronchi: What Are They, Function, Anatomy & Conditions

Involuntarily controlled muscle that regulates airflow by contracting (bronchoconstriction) or relaxing (bronchodilation). Histological Layers: These supply each lobe of the

Lined with ciliated pseudostratified columnar epithelium and goblet cells that produce mucus to trap dust and pathogens. Physiological Functions
