Lined with ciliated pseudostratified columnar epithelium and goblet cells that produce mucus to trap dust and pathogens. Physiological Functions
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 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
These supply each lobe of the lung (three on the right, two on the left).
Further divisions that supply specific bronchopulmonary segments. Histological Layers: Anatomy and Structure The first branch into the
Hyaline cartilage provides structural support to keep the airways open during the pressure changes of breathing.
Involuntarily controlled muscle that regulates airflow by contracting (bronchoconstriction) or relaxing (bronchodilation). Anatomy & Conditions
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
