The local matching of blood flow with ventilation is ________.

Option 1: Ventilation-Perfusion Coupling
Option 2: The Bohr Effect
Option 3: Chloride Shifting
Option 4: The Haldane Effect

Answer :

Final answer:

The local matching of blood flow with ventilation is referred to as Ventilation-Perfusion Coupling, which ensures that adequate oxygen reaches all tissues in the body. The other options are associated with how oxygen and carbon dioxide is transported and dissociated in the blood.

Explanation:

The local matching of blood flow with ventilation is referred to as Ventilation-Perfusion Coupling. In the body, Ventilation-Perfusion Coupling is responsible for ensuring that the oxygen supply and blood flow to the lung tissues are matched. If there is more ventilation, the blood vessels will dilate to carry more blood to that area and the opposite will occur if there is less ventilation. This is how the body ensures that all tissues get enough oxygen. The Bohr Effect, Chloride Shifting, and The Haldane Effect are all related to the transportation and dissociation of oxygen and carbon dioxide in the blood, and not how ventilation is locally matched with blood flow.
