BIOL 3150 CHAPTER 25 EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
What is the functional layer of the respiratory system?
alveoli
What is the main function of the respiratory system?
pulmonary ventilation (breathing); inhalation (air in) and exhalation (air out)
Secondary functions of the respiratory system
gas conditioning (warm, filter, and humidify), sound production for communication,
olfaction, defense
What is the location of the main function of the respiratory system?
respiratory membranes
What type of tissue makes up respiratory membranes?
simple squamous epithelium (rapid diffusion)
Conducting Zone
nose, nasal cavity, pharynx, larynx, trachea, bronchi, terminal bronchioles; just for air
flow
Respiratory Zone
respiratory bronchioles, alveolar duct, alveoli; for gas exchange
What makes up the upper respiratory tract?
sinuses, nasal cavity, pharynx, and larynx
What makes up the lower respiratory tract?
trachea, bronchi, and lungs
Uvula
, covers nasal cavity so food doesn't come into nose
Is the trachea open or closed?
open
Epiglottis
prevents food from entering trachea
Hard Palate
separates nasal and oral cavities to allow you to chew and breathe at the same time
Where is the nasopharynx located?
behind nasal cavity
Where is the oropharynx located?
behind mouth
Where is the laryngopharynx located?
above esophagus
Paranasal Sinuses
fill with mucus, decrease bone weight, resonance chambers for vocal sounds
Where is the voice box located?
larynx
What are the 9 cartilages in the larynx held together by?
ligaments
Laryngeal Prominence
adam's apple
Trachea
flexible, slightly rigid tubular organ
