Respiratory
Question | Answer |
---|---|
Respiratory zone | Site of gas exchange- respiratory bronchioles, alveolar ducts, and alveoli |
Respiratory bronchioles | First in the resp zone, simple cuboidal epithelium, |
Alveolar ducts | Second in the resp zone, thin airways, simple squamous epithelium |
Alveoli | Third in the resp zone, saccular outpocketings, simple squamous epithelium |
Surfactant | Inner alveolar surface, supports the structure of the alveolus |
Boyle's Law | P1V1=P2V2; at a constant temperature, the pressure of a gas decreases if the volume of the container increases and vice versa |
Intrapulmonary pressure | Pressure in the lungs; intra-alveolar pressure; |
Intrapleural pressure | pressure in the plural cavity; lower than the pressure in the lungs (intrapulmonary) |
Pathway of the respiratory system | Nose, Nasopharynx, Oropharynx, Laryngopharynx, Larynx, Trachea, Main Bronchi, Lobar Bronchi, Segmental Bronchi, Terminal Bronchioles, Respiratory Bronchioles, Alveolar ducts, Alveolar Sacs |
Laryngeal Prominence | Thyroid cartilage with laryngeal prominence (Adam’s apple) |
Functional anatomy | Conducting zone: conduits to gas exchange sites Includes all other respiratory structures Respiratory muscles: Diaphram Respiratory zone: site of gas exchange Microscopic structures: respiratory bronchioles, alveolar ducts, and alveoli |
Sound production | Speech: release of expired air opening/closing the glottis Pitch:length/tension of vocal cords Loudness: force of air Pharynx, oral, nasal, and sinus cavities amplify/sound quality Sound is “shaped” by pharynx, tongue, soft palate, and lips |
Anatomy of the lungs | Apex-top; Right-3 lobes; Left- Cardiac notch; |
Hilum | bronchi, pulmonary vessels, lymph vessels, and the pulmonary plexus autonomic nerves |
Bronchiopulmonary segments | Right- 10; Left- 8-10 |
