Collectively, the bronchi, bronchioles, larynx, nose, pharynx and trachea make up the:

The collectively mentioned structures—bronchi, bronchioles, larynx, nose, pharynx, and trachea—make up the respiratory system. The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide, facilitating gas exchange necessary for respiration. Each part plays a critical role:

• Nose: Filters, warms, and humidifies the air.
• Pharynx: Serves as a pathway for air and food.
• Larynx: Contains the vocal cords and is involved in sound production.
• Trachea: The windpipe that conducts air to the bronchi.
• Bronchi: Larger air passages that diverge from the trachea.
• Bronchioles: Smaller branches of the bronchi leading to the alveoli where gas exchange occurs.

Together, these structures ensure efficient airflow and gas exchange, vital for maintaining the body’s respiratory needs.
