This is not a complete list of vocabulary that may appear on the upcoming test.
Some concepts that you may have to learn on your own:
Effect of gravity on blood flow through lung of person at rest.
Production of sound using the vocal folds of the larynx.
The difference between partial pressure of a gas in a space and the concentration of the
gas in solution in a liquid.
Some concepts you must know for next test:
Functions of the respiratory system.
General anatomy of the respiratory system.
The path of air beginning at the nares and ending at the alveoli.
O2 and CO2 levels in alveoli, pulmonary blood, and systemic capillaries.
The muscular movements behind inspiration and expiration. Causes behind air flow.
The construction of the lower respiratory system including the alveoli.
General measures of lung function.
Control over respiration: changes in respiratory rate, changes in pulmonary blood
pressure, bronchodialation, changes in hemoglobin O2 carrying ability, chemoreceptor
activity.
Protecting the respiratory system from particles and infectious agents.
