    A structure that is not included in the respiratory system is the:

    • Nose

    • Esophagus

    • Trachea

    • Lungs

    Correct Answer
    A. Esophagus
    Explanation
    The esophagus is not included in the respiratory system because it is part of the digestive system. It is a muscular tube that connects the throat to the stomach and is responsible for transporting food and liquids from the mouth to the stomach for digestion. In contrast, the nose, trachea, and lungs are all essential components of the respiratory system. The nose filters, warms, and moistens the air we breathe, while the trachea carries air from the nose to the lungs. The lungs are the main organs of respiration, where oxygen is taken in and carbon dioxide is expelled.
