Answer:
As bicarbonate ions present in blood plasma
Explanation:
Most carbon dioxide produced by tissues (approximately 75%) is transported in the blood to the lungs as bicarbonate ions (HCO₃⁻).
<u>The chemical equilibrium is:</u>
<h3>CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3>
carbonic acid
In the lungs, the conversion is reversed, so CO₂ diffuses from the blood into the alveoli and then it's exhaled.
Although most CO₂ is reversibly converted to bicarbonte, approximately 5% is simply dissolved in the blood plasma and about 20% is bound with hemoglobin.
This conversion to bicarbonate ions keeps the partial pressure of CO₂ in blood plasma low, facilitating its diffusion away from the tissues.
