Partial pressure: the pressure exerted by each type of gas in a mixture, dalton's law, water vapor pressure.
Diffusion of gases through liquids: concentation of gas in a liquid is determined by its partial pressure and its solubility coefficient. Henry's law
physical principles of gas exchange
minute and alveolar ventilation
Minute ventilation : total amount of air moved into and out of respiratory system per minute. Respiratory rate or frequency : number breaths taken per minute. Anatomic dead space : part of respiratory system where gas exchange does not take place.
Alveolar ventilation : how much air per minute enters the parts of the respiratory system in which gas exchange takes place.
