Document Summary

Functions of the respiratory system: gas exchange, gas conditioning (warming the air and removing particles and pathogens, sound production, olfaction, defense. Gross anatomy: two anatomical tracts, upper respiratory tract (sinuses, nose, nasal cavity, and pharynx, lower respiratory tract (larynx, trachea, bronchi and lungs, two functional portions, the conducting portion (transportation of air, respiratory portion (gas exchange) Irritation to the epithelium by inhaled stuff or friction causes the mucous production rate to increase. The nasal cavity: nasal cavity- nasal conchae (superior, middle, and inferior, nasal vestibule, nostril, cribriform plate of ethmoid bone, posterior nasal aperture. The upper respiratory tract: tonsil, eustachian tube, nasopharynx, olfactory nerve, superior nasal concha, middle nasal concha. Paranasal sinuses: named for the bones in which they reside, frontal, sphenoidal, ethmoidal, maxillary. Pharynx: throat, food, drink and air pass through, 3 regions, nasopharynx (air only, oropharynx, laryngopharynx, naso: pseudostratified columnar epithelium, oro and laryngo: stratified squamous epithelium. Lower respiratory tract larynx , trachea, bronchi, bronchioles, alveolar ducts, alveoli.

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
