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.

Answer:
No, because Pneumonia can be transferred from one person to another.
Explanation:
Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.
