Document Summary

Supply o2 to body & remove byproduct (co2) Structural: upper nose, pharynx, lower larynx, trachea, bronchi, lungs. Functional: conducting zone nasal cavities (terminal bronchioles), filter, warm and moisten air, conduct air to respiratory zone, respiratory zone respiratory bronchioles (alveoli), gas exchange. Air enters through external nares (i. e. nostrils) Functions: warming and moistening, factory receptors (senses) Function: vocalization, open passage for air into lungs, prevents food from entering trachea. Structure: suspended from hyoid bone (thyrohyoid membrane, 9 cartilages (3 bilateral and 3 individual, continues inferiorly with trachea. Swallowing: larynx & pharynx pulled superior during swallowing, epiglottis folds down to close larynx, pharynx widens when pulled superior. Breathing: epiglottis is open (larynx is open, rima glottis is patent. Sit in abducted position while breathing adduct to talk. Made of smooth muscle, connective tissue, c- shaped cartilage. Divides @ carina right and left primary bronchi. Pneumothorax collapsed lung, air in pleural cavity. Conducting zone: trachea 1 bronchia 2 bronchi 3 bronchi bronchiole.

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
