BIOD 151 Lab 2
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)
Pulmonary Fibrosis
formation of scar tissue in the connective tissue of the lungs
Emphysema
a condition in which the air sacs of the lungs are damaged and enlarged, causing
breathlessness.
Tidal Volume
amount of air inhaled or exhaled with each breath under resting conditions
Inspiratory Reserve Volume
the maximal amount of additional air that can be drawn into the lungs by determined
effort after normal inspiration
Expiratory Reserve Volume
Amount of air that can be forcefully exhaled after a normal tidal volume exhalation
Residual Volume
The volume of air remaining in lungs after maximum exhalation.
Vital Capacity
the greatest volume of air that can be expelled from the lungs after taking the deepest
possible breath.
Inspiratory Capacity
maximum amount of air that can be inhaled after a normal tidal expiration
Functional Residual Capacity
