Bronchi are the larger air passages that extend from the trachea and branch into the lungs. Their primary function is to deliver air from the trachea into the lungs for gas exchange.
They further divide into smaller bronchioles, which lead to tiny air sacs called alveoli.
he bronchi’s structure includes cartilage, which provides structural support to keep the airways open. Mucus-producing cells within the bronchi help trap and remove foreign particles and irritants.
Additionally, the bronchi contain smooth muscle that can contract or relax, regulating airflow and contributing to efficient respiratory function, ensuring oxygen intake and carbon dioxide removal for sustaining bodily processes.
