The main function of the bronchi is to conduct air to and from the lungs. The bronchi are the large air passages that branch off from the trachea (the windpipe). They divide into smaller bronchi and eventually into bronchioles, which lead to the alveoli, where gas exchange occurs. The bronchi also help filter, warm, and humidify the air before it reaches the lungs, as well as protect the respiratory system by trapping and removing particles and pathogens via mucus and cilia.
