Questions and Answers

What is the function of the nose in the pulmonary system?

  • Excretes large amounts of water and heat
  • Produces vocal sounds (phonation)
  • Contains receptors for sense of taste
  • Filters, warms, and humidifies air entering the lungs (correct)

    • What is the function of the larynx in the pulmonary system?

  • Filters inspired air and regulates blood pH
  • Contains receptors for sense of smell
  • Connects nasal and oral cavities to the larynx
  • Connects pharynx to trachea and is involved in voice production (correct)

    • What is the main function of the trachea in the pulmonary system?

  • Connects pharynx to trachea
  • Filters, warms, and humidifies air entering the lungs
  • Produces vocal sounds (phonation)
  • Cleans, warms, and moistens incoming air (correct)

    Study Notes

    Pulmonary System Functions and Structure

    • The pulmonary system provides gas exchange, regulates blood pH, contains receptors for smell, filters air, produces vocal sounds, and excretes water and heat.
    • Ventilation involves the transport of oxygen and carbon dioxide into and out of the lungs, while respiration is the exchange of gases across specific interfaces.
    • Functionally, the pulmonary system is divided into the conduction zone (nose, pharynx, larynx, trachea, bronchi, terminal bronchioles) and the respiratory zone (respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli).
    • Structurally, it consists of the upper respiratory system (nose, pharynx, larynx) and the lower respiratory system (trachea, bronchi, bronchioles, alveoli).
    • The nose filters, warms, and humidifies air, while the pharynx serves as a conduit for air and food.
    • The larynx connects the pharynx to the trachea, contains vocal folds, and prevents food from entering the lower pulmonary tract.
    • The larynx includes various cartilages such as thyroid, cricoid, arytenoid, corniculate, cuneiform, and epiglottis.
    • The trachea is a flexible tube with C-shaped cartilaginous rings, dividing into left and right main stem bronchi at the carina, and cleans, warms, and moistens incoming air.
    • The tracheobronchial tree has 23 generations, including the conducting zone (main bronchi, lobar bronchi, segmental bronchi, terminal bronchioles) and the respiratory zone (respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli).
