    What is the function of the upper airway?

    Filters, warms, and humidifies inhaled air.

    How do bronchi differ from bronchioles?

    Bronchi have cartilage; bronchioles rely on elastic fibers.

    What happens during inhalation?

    Thoracic volume increases, causing air to flow in.

    What is the role of alveoli in gas exchange?

    Provide a large surface area for rapid diffusion.

    What protects the airway during swallowing?

    The epiglottis prevents food from entering the trachea.

    What occurs during exhalation?

    Thoracic volume decreases, pushing air out of the lungs.

    How does the respiratory system regulate blood pH?

    By adjusting ventilation rates to modulate CO2 levels.

    What is the significance of surfactant in the lungs?

    Keeps alveoli open and efficient for gas exchange.

    What is the primary gas exchanged in the lungs?

    Oxygen is taken up while carbon dioxide is released.

    What factors affect gas exchange efficiency?

    Surface area, membrane thickness, and blood flow.
