| Question | Answer |
| 1. Human Anatomy and Physiology The Respiratory System Functional anatomy of the respiratory system: Conducting Zone Rigid conduits for air to reach site of gas exchange -nose -nasal cavity -pharynx -larynx -trachea -bronchi Respiratory Zone site of gas e | |
| 2. Human Anatomy and Physiology The conducting zone Conducting Zone: Nose -airway -moistens and warms air -filters inspired air -resonating chamber for speech -olfaction -paranasal sinuses -frontal, sphenoid, ethmoid and maxillary bones -warm and moisten | |
| 3. Human Anatomy and Physiology The conducting zone Conducting Zone: Pharynx -connects the nasal cavity and mouth to the larynx and esophagus -common pathway for food and air (throat) -nasopharynx -oropharynx -laryngopharynx | |
| 4. Human Anatomy and Physiology The conducting zone Conducting Zone: Laryngopharynx – common passage way for food and air Larynx – voice box | |
| 5. Human Anatomy and Physiology The conducting zone Conducting Zone: Trachea -windpipe -larynx at division forming two primary bronchi at midthorax -mucosa – pseudostratified epithelium (goblet cells) -submucosa – connective tissue seromucous glands – muc | |
| 6. Human Anatomy and Physiology The conducting zone Conducting Zone: Bronchi Bronchial tree -left and right primary bronchi -formed by divisions of the trachea -secondary bronchi (lobar) -inside the lungs -3 on the right -2 on the left -tertiary bronchi ( | |
| 7. Human Anatomy and Physiology The conducting zone Conducting Zone: Bronchioles -bronchioles (under 1 mm in diameter) -terminal bronchioiles (less than 0.5 mm) | |
| 8. Human Anatomy and Physiology The conducting zone Conducting Zone: Cartilage: -rings -irregular plates -no cartilage in bronchioles -replaced by elastic fibers Epithelium: -pseudostratified (ciliated) -columnar (ciliated) -cuboidal in terminal bronchiol | |
| 9. Human Anatomy and Physiology The respiratory zone Respiratory Zone: Respiratory bronchioiles Alveoli (300 million) Alveolar ducts Alveolar sacs Gas Exchange: respiratory membrane | |
| 10. Human Anatomy and Physiology The respiratory zone Respiratory Zone: Respiratory membrane (air-blood barrier) or (Alveolar-capillary membrane) is composed of: -simple squamous epithelial cells (Type I cells) -cobweb of pulmonary capillaries Primary fun | |
| 11. Human Anatomy and Physiology Lungs and Pleural Coverings Pleural Coverings: -double layered serosa -parietal pleura lines the thoracic wall -pulmonary or visceral pleura which covers the lung surface -pleural cavity is the space between the two layers |
