The conducting passageways of the respiratory system include all of the following structures EXCEPT
pharynx
larynx
trachea
esophagus
Which of the following is NOT a function of respiratory conducting passageways?
allow air to reach the lungs
humidify air
exchange gases
warm incoming air
Speech results from exhaled air causing vibration of
pharynx
larynx
trachea
esophagus
Cilia in the trachea that beat continually propel contaminated mucus
toward the pharynx to be swallowed or spat out
toward the mouth to be digested
toward the nose to be sneezed out
toward the larynx to be coughed out
The nasal cavity is separated from the oral cavity by
the tongue
the nasal septum
the tongue
the palate
Which of the following statements about the lungs is NOT true?
the narrow portion of each lung is called the apex
the base rests on the diaphragm
the right lung has three lobes
they are the only major organ in the thoracic cavity
Exchange of oxygen and carbon dioxide through the respiratory membrane occurs by
simple diffusion
active transport
pressure changes
passive transport
The exchange of air that occurs between the alveoli and the pulmonary capillaries is
internal respiration
pulmonary ventilation
inspiration
external respiration
Which one of the following is NOT true of inspiration
contraction of the diaphragm muscle helps increase the size of the thoracic cavity
the base rests on the diaphragm
the right lung has three lobes
they are the only major organ in the thoracic cavity
Which one of the following is NOT true of expiration
the diaphragm relaxes
it is mostly a passive process
gas flows out to equalize pressure inside and outside the lungs
intrapulmonary volume increases when the lungs recoil (get smaller)
Most carbon dioxide is transported within blood plasma as
hemoglobin
bicarbonate ion
hydrogen ion
carbonic acid
Which of the following is NOT one of the four events of respiration?
Pulmonary Ventilation – breathing, moves air into and out of lungs
Hyperventilation – shallow breathing that often occurs after trauma or surgery
Respiratory Gas Transport – O₂ and CO₂ are carried by the blood
Which of the following statements is NOT true?
The visceral pleura covers the external surface of the lungs.
The medulla and pons of the brainstem regulate breathing.
The larynx is a common passageway for air and food.
The hard palate is supported by bone and is anterior to the soft palate.
Which one of the following statements is NOT accurate regarding the lungs?
each one is about the size of a softball
divided into sections called lobes
located in the thoracic cavity
contain millions of alveoli
Which of the following statements correctly describes the mucus membranes of the respiratory tract?
warm, moist, lined with cilia
cool, dry
warm, dry, lined with cells that secrete mucus
cool, moist, with many capillaries
Which of the following is NOT a function or accurate description of the larynx?
houses the vocal cords
cool, dry
warm, dry, lined with cells that secrete mucus
cool, moist, with many capillaries
Which of the following statements is NOT accurate regarding the trachea?
the epiglottis prevents food from entering
supported by c-shaped rings of cartilage
located posterior to the esophagus
divides into 2 primary bronchi
Which of the following lists the correct path of air into the lungs?
nasal cavity – pharynx – trachea – bronchi – bronchioles – alveoli
nasal cavity – larynx – trachea – alveoli – bronchioles – bronchi
nasal cavity – trachea – larynx – bronchioles – bronchi – alveoli
nasal cavity – oral cavity – pharynx – trachea – bronchi – alveoli
Which of the following statements regarding alveoli is NOT correct?
they are arranged in grape-like clusters
they have extremely thin walls
they are filled with blood
they have a very large surface area
Which of the following statements regarding lung volumes is NOT correct?
Lung volumes are measured with a spirometer.
Tidal volume is the amount of air breathed in and out without conscious effort.
People typically use about 50% of their lung capacity.
Males usually have larger lung volumes than females.
