BIOD 151 LAB 2 EXAM QUESTIONS WITH COMPLETE
SOLUTIONS VERIFIED GRADED A+
Pharynx
throat; passageway for food to the esophagus and air to the larynx
Larynx
voice box; passageway for air moving from pharynx to trachea; contains vocal cords
Trachea
a large membranous tube reinforced by rings of cartilage, extending from the larynx to
the bronchial tubes and conveying air to and from the lungs; the windpipe.
Bronchi/Bronchus
The two tubes formed when the trachea divides into two, one passes into each lung
Bronchioles
smallest branches of the bronchi
Alveoli
tiny sacs of lung tissue specialized for the movement of gases between air and blood
Anatomical dead space
the conducting zone; airways that fill with air but cannot perform gas exchange (30
percent)
Alveolar Ventilation Rate
measures the flow of fresh gas in and out of alveoli during a particular time interval
(ml/min)
Spirometer
An instrument for measuring the air entering and leaving the lungs.
Spirometry
a measurement of breathing (or lung volumes)
