Document Summary

Superior nasal conchae, middle nasal conchae, inferior middle conchae nasal meatus slows down and conditions air before system it goes o o o to lungs (superior, middle, inferior) lined with mucous, throat (pharynx) Conducting portion (series of air passages to get air to respiratory portion) external nares respiratory bronchioles o. Respiratory portion (anywhere gas exchange can take place) respiratory bronchioles alveoli. Gas conditioning (preparing air to maximize gas exchange once it reaches respiratory portion) as air works its way through nasal cavity (warmed, humidified, contact with mucous filters it) Sound production (larynx voice box, paranasal sinuses resonate sound, tongue and teeth) Olfaction (olfactory epithelium in nasal cavity inferior to cribriform plate, odor molecules are dissolved and bind to receptor molecules) Pseudo-stratified ciliated columnar epithelium (shape = columnar, ciliated = hair-like structures, o stratifies = layered, pseudo = false) o. Goblet cells (oval shaped, blend in with epithelium cells, produce mucous)

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
