Definition

The bronchi are conduits that are components of an organism's respiratory system. The two principal bronchi, or mainstream bronchi, begin at the end of the trachea and connect to each lung. The lobar bronchi and bronchioles (the smallest in diameter) manage activity within the lungs. Inhaled air follows the trajectory of the trachea and the bronchi, which ensure the exchange of gases (oxygen and carbon dioxide) with blood circulation and in this way allow the oxygenation of tissues.
