the conducting portion extends from the nose to the terminal bronchi, and the respiratory from the respiratory bronchioles to the alveoli
describe the passage that air travels when its inhaled
nose/mouth–nasal cavity/oral cavity–pharynx–larynx–trachea–primary bronchi–bronchioles–alveoli
what divides the upper and lower respiratory tract
pharynx and above is upper, larynx and below is lower
what division of the respiratory system does the common cold affect
