To determine: Whether more or less oxygen is delivered to the systemic cells under the conditions of the lower cellular PO2.
Concept introduction: When the partial pressure for a specific gas is greater in one region than in another region, a partial pressure gradient exists. If a partial pressure gradient exists between two regions for a particular gas, then the gas moves to the area of lower partial pressure gradient from the area of higher partial pressure gradient. This movement may continue until the partial pressures in both the regions become equal. The respiratory gas exchange in both systematic and alveolar gas exchange is dependent upon the partial pressure gradients.
To determine: Whether the oxygen reserve is higher or lower.
Concept introduction: The respiratory system is the biological system that consists of specific organs and structures used for the gas exchange in animals. Gas exchange is the transport of respiratory gases between blood and either alveoli or cells of systemic tissues. During breathing, the gases in air move down collectively the pressure gradient, whereas each gas moves down independently its own partial pressure during gas exchange.
