Final answer:
Approximately 5 to 7 percent of carbon dioxide is transported dissolved in blood plasma, with the most accurate option for the quantity being D. 23%, representing a small fraction of carbon dioxide in the plasma that is exhaled in the lungs.
Step-by-step explanation:
The question asks us to match the method and approximate quantity of carbon dioxide transport from tissues to the lungs using dissolution in blood plasma. Carbon dioxide is transported from body tissues to the lungs by three main methods:
- Dissolution directly into the blood.
- Binding to hemoglobin.
- Being carried as a bicarbonate ion.
About 5 to 7 percent of all carbon dioxide is dissolved in the plasma. Given the options provided (A. -0%, B. -23%, C. 0%, D. 23%), the most accurate match for carbon dioxide dissolved in blood plasma is D. 23%, which is consistent with the provided information that a small fraction, around 7 to 10 percent, is dissolved in plasma and subsequently exhaled when reaching the pulmonary capillaries.
