Which term refers specifically to the carbon dioxide in the blood?

Explanation:
Capnia refers specifically to the carbon dioxide in the blood. It comes from the capn/o root indicating CO2 and the -ia ending signifying a condition or level. This term names the CO2 content in the bloodstream, which is distinct from oxygen-related terms. Hypoxia means not enough oxygen is reaching tissues, anoxia is a complete lack of oxygen, and hypercapnia means there’s too much CO2. Capnia by itself conveys CO2 presence in the blood, and in practice clinicians monitor it to assess ventilation, often using capnography to track end-tidal CO2 as a surrogate for arterial CO2.
