Summary Introduction
Introduction:
The oxygen tension in the blood is referred as PO2, while the carbon dioxide tension in the blood is referred as PCO2. This tension of blood gases is the partial pressure of these gases. The cells of the muscles are constantly active and require energy. Oxygen is used up in the breakdown of glucose to release ATP (adenosine triphosphate). Thus, their PO2 is lower than the blood reaching these cells or the blood reaching these cells has a relatively higher PO2.
