The upper respiratory tract includes the:
The upper respiratory tract includes the:
- nose, pharynx and larynx (correct)
- nose, trachea and lungs
- trachea, bronchi and alveoli
Inhalation involves:
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

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.
