The process of oxygen and carbon dioxide exchange that happens during respiration is a result of:

The partial pressure gas differences between alveoli and capillaries
The pressure difference between alveoli and capillaries
The volume of blood within the capillaries
The volume of gas within the alveoli

Explanation

Answer - A - The process of oxygen and carbon dioxide exchange that occurs during respiration happens as a result of the partial pressure gas differences between alveoli and capillaries. As the partial pressure of oxygen goes down within the blood, the partial pressure of carbon dioxide goes up, allowing for proper gas exchange with the alveoli. Once the pressure of oxygen goes up, the blood is ready to travel to the rest of the body.
