a) -------------------- serves as a sound resonating chamber; contains tonsils; directs air inferiorly b) ------------------- passes air from pharynx into windpipe; site of sound production c) ------------------ resonate(s) sound; not part of pharynx D) ------------------ opening from oral cavity into pharynx E) ----------------- carries air to a segment of a lung F) -------------------- carries air directly into a respiratory bronchiole G) ----------------- surround the lungs H) ------------------ reduces surface tension at sites of gas exchange i) -------------------- actual sites of gas exchange j) --------------------- normal, quiet breathing k) ----------------------- shallow breathing using just the external intercostal muscles l) ------------------ amount of effort required to expand the lungs and chest wall m) ------------------- tidal volume + inspiratory reserve volume, usually about 3600 mL in males n) ----------------- tidal volume + inspiratory reserve volume + expiratory reserve volume; usually about 4800 mL in males o) ------------------- residual volume + expiratory reserve volume; usually about 2400 mL in males p) -------------------- states that the amount of gas that will dissolve in a liquid is proportional to the partial pressure of that gas and its solubility q) ---------------- when pH decreases, O2 saturation of hemoglobin decreases r) ------------------ each gas in a mixture of gases exerts its own partial pressure s) ------------------- sets basic rhythm of breathing t) ------------------------ includes the pontine respiratory group |
