Document Summary
Boyle"s law -> as volume increases, air pressure decreases. 2 floating rib- head, neck, shaft, angle: pelvic girdle. Both act as an a shape frame for back muscles. Carina trachea is point where it divides into mainstem. Divides into tertiary that keep branching out. Function to protect lower respiratory tract: oral cavity. Provides communication between buccal/oral cavity (esophagus) and nasal cavity (larynx: nasal cavity. 16 to 20 cartilaginous rings open posteriorly to accommodate attachment of esophagus. Goal of respiration: oxygenation of blood, eliminate co2 and waste. Doesn"t require muscles of expiration: active. Respiratory cycle: one inhalation and one exhalation, 12 to 18 for adults, a lot more for babies: 40-70, reached full capacity by age 8- 25 to 300 million, quiet tidal. 600 for guys: adult has air never expelled but infant doesn"t have that. Volume beyond regular tidal volume: expiratory reserve volume (erv) Volume of expiration beyond regular tidal volume: tidal volume.
