The bronchial tubes then divide into bronchioles, which are even smaller air passages. Tiny air sacs, called alveoli, are on the ends of the bronchioles.The small tubes located within the lungs are known as the bronchial tubes.

What are the jobs of the organs in the respiratory system?

Your trachea, mouth and nose allow air to enter your body. They both filter the air. The nose filters the air by the cilia, and the mouth by mucus. Those help because they catch the dirt from the air and prevent it from going into your lungs. The air gets warmed by your nasal cavity into the trachea. Your epiglottis stops air going into your stomach. Your lungs are near your heart, and after air goes through your trachea, it goes in your bronchial tubes, which let air into your lungs Your bronchial tubes branch through your lungs. Alveoli are the little air sacs at the end of your bronchial tubes where air enters.
