支气管
a major airway in the respiratory system that branches off from the trachea and leads to the lungsea
The bronchus, also known as a bronchial tube, is a primary airway in the human respiratory system that carries air from the trachea into the lungs. It branches off into smaller bronchi, which further divide into bronchioles, allowing for the distribution of air to the different regions of the lungs. The bronchus is lined with ciliated cells and mucus-producing cells that help to filter and moisten the air, ensuring optimal lung function and gas exchange.
