Laryngitis
Laryngitis is potentially dangerous condition because it may cause (Obstruction of the airway)
visceral and parietal pleural membranes
The visceral and parietal pleural membranes are normally held together by (Surface tension)
spirometer
Which of the following are volumes that cannot be measured using a simple spirometer? (Residual volume)
Hyperventilation
Hyperventilation is most likely to be accompanied by a(an) (Decrease in blood carbon dioxide concentration and a rise in pH )
pectoralis minors
The pectoralis minors and the sternocleidomastoid are useful in aiding forced expiration. (FALSE)
forceful expiration
During forceful expiration, the air that can be expelled from the lungs in addition to the tidal volume is called (Expiratory reserve volume)

Which of the following muscles would be most helpful for forceful expiration? (Abdominal wall muscles)
Cancer that originates in the lungs
Cancer that originates in the lungs is most likely to develop from (Epithelial cells)
vocal cords
The vocal cords are located within the (Larynx)
pleural cavity
The condition in which air enters the pleural cavity is called (Pneumothorax)
Gas exchange
Gas exchange between the air in the alveoli and the blood in nearby capillaries occurs primarily by (Diffusion )
inflation reflex
The receptors of the inflation reflex are most sensitive to (Stretch)
Breathing rate
Breathing rate is most likely to increase if the blood concentration of (Carbon dioxide increases)
carbonic anhydrase
The enzyme carbonic anhydrase causes
(Carbon dioxide to react with water)
normal expiration
The force responsible for normal expiration is supplied by (Elastic recoil of tissues and surface tension)
respiratory distress
The condition of newborns called respiratory distress syndrome is caused by (Lack of surfactant )
respiratory membrane
The respiratory membrane consists of
(Two thicknesses of epithelial cells and basement membranes)
upper respiratory tract
The organs of the upper respiratory tract are located outside the thorax. (TRUE)
inspiration
The force that causes air to move into the lungs during inspiration is supplied by (Atmospheric pressure)
normal respatory cycle
The amount of air that enters or leaves the lungs during a normal respiratory cycle is the
(Tidal volume)
alveoli
The walls of the alveoli are composed of
(Simple squamous epithelium)
procedure
The procedure used to directly examine the trachea and bronchial tree is called
(Bronchoscopy)
Microorganisms
Microorganisms removed from incoming air by sticky mucus are most likely to be destroyed by (Digestive action of gastric juice)

Microorganisms trapped in the mucus of the nasal cavity are most likely to be transported to the (Stomach )
Carbon dioxide
Carbon dioxide is sometimes added to the air that a patient breathes in order to (Increase the rate and increase the depth of breathing)
Emphysema
Emphysema is characterized by an increase in (None of these)
glottis
The glottis is the opening between the vocal cords. (TRUE)
inflation reflex
The receptors of the inflation reflex are most sensitive to
Carbon monoxide
Carbon monoxide bonds to hemoglobin more effectively than does oxygen.
(TRUE)
pectoralis minors
The pectoralis minors and the sternocleidomastoid are useful in aiding forced expiration. (
anhydrase
