Questions and Answers

The upper respiratory tract includes the:

  • nose, pharynx and larynx (correct)
  • nose, trachea and lungs
  • trachea, bronchi and alveoli
  • Inhalation involves:

  • diaphragm relaxes and arches up -> internal intercostal muscles contract and pull ribs in and down -> volume of thorax decreases -> pressure in thorax increases
  • diaphragm contracts and flattens -> external intercostal muscles contract and pull ribs up and out -> volume of thorax increases -> pressure in thorax decreases (correct)
  • diaphragm contracts and flattens -> external intercostal muscles contract and pull ribs up and out -> volume of thorax decreases -> pressure in thorax increases
  • The function of the vestibules is to:

  • filter air, warm air and moisten air (correct)
  • filter air, warm air and dry air
  • saturate air with water vapour

    Study Notes

    Respiratory System Tutorial Questions

    • Upper Respiratory Tract: Includes the nose, pharynx, and larynx. Trachea, bronchi, and alveoli are also part of the respiratory system.
    • Inhalation: Involves diaphragm contraction and flattening, external intercostal muscle contraction, pulling ribs up and out, increasing thoracic volume, and decreasing thoracic pressure.
    • Vestibule Function: The vestibules filter, warm, and moisten air. Air is not dried.
    • Pharyngeal Domains: The correct order of pharyngeal domains is nasopharynx, oropharynx, and laryngopharynx, progressing to the oesophagus.
    • Larynx Function: The larynx closes and seals the respiratory tract, also producing sound and filtering dust and particulates.

    Additional Respiratory System Details

    • Trachea and Bronchi Cartilage: The rings of cartilage in the trachea and bronchi are C-shaped.
    • Alveoli Count: The human lungs have approximately 600 million alveoli.
    • Hilum Structures: The hilum allows entry/exit of pulmonary veins, arteries, bronchial veins, arteries, and nerves.
    • Lung Lobes: The right lung has 3 lobes, and the left lung has 2 lobes.
    • Cardiac Notch: The cardiac notch is located in the left lung, near the apex.
    • Lung Volumes: Lung volumes include tidal volume, vital capacity, and residual volume.
    • Oxygen Transport: Oxygen travels in the blood as oxyhemoglobin.
    • Surfactant Production: Surfactant production begins at 34 weeks.
    • Emphysema Characteristic: Emphysema involves a progressive loss of elasticity in the alveoli.
    • Bronchopneumonia Inflammation: Bronchopneumonia involves acute inflammation, especially at lower lobes of the lungs. Inflammation occurs at ends of the bronchioles.
