respiratory system Flashcards
functions of the respiratory system
gas exchange, air distribution, air modification, body temperature regulation, acid-base balance, voice production, olfaction
air distribution
airways in the lungs are responsible for distributing inhaled air to the small air sacs where gas exchange takes place
external respiration
oxygenated blood will carry the O2 throughout the body, carbon dioxide in blood returning to the lungs is diffused back to the air
internal respiration
at the cellular level in the body, the O2 is exchanged for the waste carbon dioxide
air modification
passing through the respiratory tract, the inhaled air is filtered, warmed, and humidified
voice production
vocal cords are two fibrous connective tissue bands attached to cartilage in the larynx
