Answer 2

The concentration of which of the following substances increases in the blood that is coming out of the tissues (ii) $CO_{2}$.

Carbon dioxide is carried in the blood:

• There are three ways that carbon dioxide is delivered through the blood from the tissue to the lungs.
• 1. attached to proteins, especially hemoglobin;
• 2. dissolved in solution;
• 3. buffered with water as carbonic acid.
• About 75% of the carbon dioxide is transported by red blood cells, and 25% is transported by plasma.
• $CO_{2}$ is carried by the bloodstream to the lungs, where it is eventually exhaled out of the body.
• Numerous functions $CO_{2}$ in the human body include blood pH adjustment, respiratory drive, and hemoglobin's affinity for oxygen ($O_{2}$).
