ventilation (breathing)
gas exchange within the lungs
O2 utilization within the cells.
all of the above

nasal cavity
pharynx
trachea
esophagus
bronchus
The functions of the respiratory system include all of the following except
providing oxygen to the bloodstream and removing carbon dioxide
creating air pressure that allows for swallowing
enabling the vocalization as expired air passes over the vocal cords
assisting in abdominal compression

meatuses
uvula
nasal septum
vibrissae

superior concha
nasal bone
sphenoid bone
cribriform plate of the ethmoid bone
choana

goblet cells
vestibule
adenoids
choanae
mast cells
Which of the following is not a paranasal sinus?
maxillary sinus
pterygoidal sinus
sphenoidal sinus
frontal sinus
ethmoidal sinus
The "Adam' s apple" is the
trachea
thyroid cartilage
larynx
epiglottis
In this image, the swimmer is taking a large breath in. Which of the following processes occurs during inhalation?
Choose all answers that apply:
The diaphragm is relaxed and the volume in the lung decreases.
The pressure in the lungs is lower than the external environment.
External intercostal muscles are relaxed.
The diaphragm is contracted and pulling the lungs down to increase the lung volume.
The ribs are recoiled.
Structure #5 is the esophagus.
True
False
Structure #3 ensures food does not go into the trachea.
True
False
Structure #4 does not represent the vocal cords.
True
False
Structure #4 vibrate and create sound.
True
False
A man swallows a whole grape that does not enter the esophagus. Unfortunately, the ____________ did not function properly and diverted the grape into the respiratory tract instead of the esophagus.
epiglottis
pharynx
cardiac sphincter
The following CT image is taken with a patient facing towards you. The patient was diagnosed with a tumor (letter “A”) in his respiratory system. Name the structure in which the tumor is located.
Trachea
Diaphragm
Left lung
Right lung
How do the lungs contribute to thermoregulation?
The lungs contain water that cool the surrounding organs
The lungs create heat through catabolic reactions involving ATP within the alveoli
The lungs expel excess body heat during exhalation
The lungs do not play a role in thermoregulation
Air passes through which of the following structures to reach the lung.
Trachea
Epiglottis
Heart
Diaphragm
Pharynx
In the image above, structure #4 represents the
bronchi
alveoli
trachea
bronchioles
Select all of the following true statements about the alveoli.
Capillaries discard oxygen here and pick up carbon dioxide.
Their large surface area maximizes gas exchange.
Although small in size, they are large in number.
Their walls are only one cell thick to allow for efficient gas exchange.
The small size of the structure prevents large particles from entering the lungs.
Pneumonia can be caused by a bacterium or a virus.
True
False
Apnea is used to describe someone who is coughing or sneezing.
True
False
The process of breathing in and out is called:
Inhalation
Ventilation
Exhalation
Emphysema
Pneumonia causes:
