In order for oxygen to diffuse into the blood during inhalation, what is true about blood concentration?
both gases are at equivalent levels
carbon dioxide levels are low
oxygen levels are high
oxygen levels are low
If Eurythrocytes only carry about 15% of the CO2 produced by cellular respiration, why would an individual with anemia report shortness of breath?
Fewer red blood cells to convert CO2 to HCO3- + H+ in the blood will trigger an increase in the pH and a decrease in ventilation, or shortness of breath.
Fewer red blood cells to convert CO2 to HCO3- + H+ in the blood will result in a decreased pH and an increase in ventilation, or shortness of breath.
Fewer red blood cells convert HCO3- into H+ and CO2 in the plasma triggering an decrease in ventilation, or shortness of breath.
Fewer red blood cells convert HCO3- into H+ and CO2 in the plasma triggering an increase in ventilation, or shortness of breath.
What is the compound called when oxygen binds with hemoglobin in a person?
oxyplasma
oxyhemoglobin
carbon dioxide
bicarbonate ion
Which of the following would be a direct result of this Emphysema?
alveoli would be unable to distribute air equally throughout the lungs
capillaries surrounding the alveoli would absorb excess carbon dioxide
lower amounts of oxygen would diffuse across the membranes of alveoli into the bloodstream
less particulate matter would be trapped by mucous in the alveoli
Which of the following accurately describes the relationship between the gas laws and pulmonary ventilation?
When the intercostals contract, the lung volume increases causing exhalation.
When the intercostals contract, the lung volume increases causing inhalation.
When the diaphragm contracts, lung volume increases causing a decrease in pressure leading to inhalation.
When the diaphragm contracts, lung volume increases causing a decrease in pressure leading to exhalation.
What is the process called when air moves in and out of the lungs?
internal respiration
internal ventilation
external respiration
pulmonary ventilation
Which molecules transport the majority of the carbon dioxide in the blood?
carbohemoglobin
bicarbonate ions
hydrogen ions

In humans, what process allows the gas exchange of both oxygen and carbon dioxide through the respiratory membrane?
active transport
passive transport
simple diffusion
osmosis
A problem with the secretion of pulmonary surfactant would cause which of the following problems to occur?
gas diffusion rates would decrease in the alveoli
filling of the pleural cavity with fluid would be prevented
lungs would leak fluid into other cavities
overinflation of the alveoli would occur following exhalation
Where does exchange of gases between the outside environment and the human body?
nasal passageway
trachea
larynx
alveoli
Nicole was hyperventilating and her sister told her to breath into a paper bag. Her breathing returned to normal after her sister explained how respiratory drive works. Which did she assess as the PRIMARY factor that controls breathing rate?
