Question 118-36 : The type of hypoxia which occurs at altitude is a explained by ?

Dalton's law

.dalton's law tells us that the total pressure of any mixture of gases with constant temperature and volume is the sum of the individual pressures also called partial pressure of each gas in the mixture also partial pressure of each gas is proportional to that gas's percentage of the total mixture because the percentage of oxygen in the atmosphere remains constant at 21% dalton's law lets us calculate the partial pressure of the oxygen in the atmosphere at any altitude .the human body is affected by the pressure of the gases in the atmosphere the partial pressure of oxygen and to a lesser extent other gases available in the surrounding air is important in determining the onset and severity of hypoxia exemple 358 Dalton's law.
