Bronchial tree under pressure

Bronchus damage: The trachea and bronchi are the breathing passages of the human body, and the tree is a plant in nature. People associate the bronchus with the tree because the shape of the trachea, bronchi and their branches is like a lush tree . However, the shape of the tree is upside down, with the trachea on the trunk and the bronchi and branches below. In addition, the trachea tree is hollow, and its lumen is a channel for airflow. If the bronchial tree is damaged, it cannot pass through it to bring fresh air into the body and expel carbon dioxide from the body.
