Bronchi
two short branches located at the lower end of the trachea that carry air into and out of the lungs.
Bronchi are the large and hollow tubular structures in the respiratory system that help to transport air in and out of the lungs. The bronchi are part of the conducting zone of the respiratory system which means that they facilitate the movement of air from the nose and mouth to the respiratory zone in the lungs.
The bronchi are formed by the division of the trachea and serve as the main passageway for air as it travels in and out of the lungs. The right bronchus is wider, shorter and more vertical than the left bronchus, making it easier for foreign objects to enter and become lodged in the right lung.
The bronchi are lined with ciliated epithelium which helps to move mucus and debris up and out of the lungs to prevent infections and maintain respiratory health. The smooth muscle in the walls of the bronchi helps to regulate the diameter of the airways and control airflow.
In summary, the bronchi play an important role in the respiratory system by transporting air in and out of the lungs while also helping to filter out unwanted particles and maintain respiratory health.
