b. nasopharynx
c. nostrils
d. nasal cavity
e. nasal septum
nasopharynx
What is the role of mucus in the nasal cavity:
trap incoming bacteria and other foreign debris
the nasal cavity is separated from the oral cavity by
both the hard and soft palate
Which one of the following bones does NOT contain paranasul sinuses:
a. frontal
b. sphenoid
c. mandible
d. ethmoid
e. maxilla
mandible
Which tonsil(s) is/are located in the oropharynx at the of the soft palate:
palatine tonsils
air from the nasal cavity enters the superior portion of the pharynx called the:
nasopharyx
Contaminated mucus is removed from the lower respiratory passageways, such as the trachea, by:
cilia
following the removal of the larynx, a person would be unable to:
speak
the opening between the vocal cords is called the:
glottis
the flap of elastic cartilage that protects food from entering the larynx when swallowing is the:
epiglottis
terminal bronchioles eventually terminate in:
alveoli
The serous membrane covering the surface of the lungs is called the:
visceral pleura
Which one of the following is NOT true of the lungs:
a. the narrower portion of each lung is called the apex
b. the bases rest on the diaphragm
c. the left lung has two lobes
d. the right lung has three lobes
e. both lungs have two lobes
e. both lungs have two lobes
When oxygen enters the respiratory system, what is the next structure to which it travels immediately upon leaving the trachea:
main (primary) bronchi
What is not part of the respiratory zone:
primary bronchi
Which of the following is NOT one of the four main events of respiration:
residual volume
Exchange of both oxygen and carbon dioxide through the respiratory membrane occurs by:
simple dissusion
The lipid molecule critical to lung function that coats the gas-exchanged alveolar surfaces is called:
surfactant
Air moving in and out of the lungs is called:
pulmonary ventilation
The gas exchange that occurs between blood and tissue cells at systemic capillaries is called:
internal respiration
Which non respiratory air movement clears the upper respiratory passageways:
sneezing
The respiratory movement representing the total amount of exchangeable air is the:
vital capacity
The amount of air that can be forcibly exhaled after a tidal expiration is about:
1200 mL
The amount of air exchange during normal quiet breathing is about:
500 mL
Which congenital respiratory disease results in the over secretion of mucus and clogging of:
cystic fibrosis
What is the most common cause for lung cancer:
smoking
Passageway for both food and air; known as the "throat"
pharynx
Rigid, patent airway reinforced with C-rings of hyaline cartilage
trachea
routes air and food into their proper channels
larynx
protects the superior opening of the larynx during swallowing
epiglottis
serous membranes surrounding the lungs
pleura
lipid (fat) molecule produced by the the alveoli to prevent alveoli collapse
surfactant
smallest conducting passageways in the lungs
bronchioles
part of the respiratory zone, these air sacs are the sites of gas exchange
alveoli
involves using the uvula to close the oral cavity off from the pharynx in order to clear the upper respiratory passages
sneezing
an emotionally induced response that produces air movements similar to crying
laughing
a very deep inspiration formerly believed to be triggered by low oxygen
yawning
primarily an emotionally induced mechanism that involves release of air in a number of short breaths, similar to laughing
crying
blast of upward rushing air that clears the lower respiratory passageways
coughing
sudden inspirations resulting from spams of the diaphragm
hiccuping
amount of air that can be forcibly exhaled after a normal tidal expiration
total lung capacity
normal, quiet breathing which moves approximately 500 mL of air per breath
tidal volume
air that enters the respiratory tract and remains within the conducting zone passageways
dead space volume
amount of air that can be inhaled forcibly over the tidal volume
inspiratory reserve volume
total amount of exchangeable air
vital capacity
air that remains in the lungs even after the most strenuous expiration
residual volume
sum total of tidal volume, inspiratory reserve volume, and expiratory reserve volume
vital capacity
