The right bronchi
Bronchi are the main airways in the respiratory system that branch off from the trachea. They are lined with mucus-producing cells and ciliated cells that help trap and remove foreign particles from the air. The bronchi also contain smooth muscle that can contract or relax to control airflow.
Cilia are responsible for removing foreign material from the trachea and bronchi. They are like little dusters that remove germs and bacteria.

a. Nose -Inspiration and expiration usually occurs through the nose. The nose has main two functions: The cilia and hairs which line the nasal cavities trap dust and other foreign particles and the rich supply of blood surrounding the cavities warms the air before it enters the lungs. b. Pharynx - allows for separation of food and air. The epiglottis closes the trachea when we eat and opens when we breathe. c. Larynx - this structure sits on top of the trachea. Air rushing across two ligaments causes sounds that we shape into speech. Also called the voice box. d. Trachea - Also called the windpipe e. Bronchi - the trachea branches into two forks each called a bronchi f. Bronchioles - the smaller and smaller passageways that come off the bronchi g. Alveoli - these are the small air sacs where actual gas exchange takes place.
