What is partial pressure in respiration?
Answers
The partial pressure is the pressure the gas if the gas were in the same volume and temperature by itself. ... Dalton's law states the total pressure of a mixture of ideal gases is the sum of the partial pressure of each individual gas.
The partial pressure of oxygen in alveolar air is about 104 mm Hg, whereas the partial pressure of the oxygenated pulmonary venous blood is about 100 mm Hg. When ventilation is sufficient, oxygen enters the alveoli at a high rate, and the partial pressure of oxygen in the alveoli remains high.
Answer:
In mixture of gases, the partial pressure is the amount of pressure each gas would exert. Partial pressure is related to respiration i.e, as air moves in the alveoli the water vapour and carbon dioxide ( CO2) are present which reduces the partial pressure exerted by oxygen to about 100mmHg.
Explanation:
Partial pressure is a measure of concentration of individual components in combination of gases. The total pressure exerted is sum of partial pressure of combination of gases.
