Lab 13- Respiratory System Exam 2026
Questions and Answers
Respiratory Tract - Answer -Passage formed by mouth, nose, throat, and lungs
through which air passes during breathings.
Pleural Cavity - Answer -Very thin potential space between the parietal and
visceral pleurae that contains serous fluid and reduces friction as the lungs change
shape and size during ventilation.
Lungs - Answer -Either of the two saclike respiratory organs in the thorax of
humans and higher vertebrae.
Nasal Cavity - Answer -Large air filled space above and behind the nose in the
middle of the face.
Pharynx - Answer -Membrane lined cavity behind the nose and mouth connecting
them to the esophagus.
Larynx - Answer -Hollow muscular organ forming an air passage to lungs and
holding vocal cords.

, Trachea - Answer -Large membranous tube reinforced by rings of cartilage
extending from larynx to bronchial tubes, converging air to lungs.
Bronchi - Answer -Any of the major air passages that branch off the trachea-
primary, secondary, tertiary, and quaternary bronchi.
Bronchioles - Answer -Tiny air passages smaller than 1 millimeter in diameter-
terminal and respiratory bronchioles.
Alveoli - Answer -Tiny air sacs in the lungs where the exchange of oxygen and
carbon dioxide takes place.
Inspiration - Answer -Process in which air is brought into the lungs.
Expiration - Answer -Process in which air is expelled from the lungs.
Boyle's Law - Answer -Relationship of gas pressure and volume
P.V.= p2v2 or P=1/V
Intrapulmonary Pressure - Answer -Pressure w/in the lungs that decreases as lung
volume increases.
Atmospheric Pressure - Answer -Must be higher that intrapulmonary pressure for
inspiration to occur. Pressure exerted by weight of the atmosphere.
Spirometer - Answer -Instrument that measures the volume of air.
