Discover how CO2 dissolves in blood and its vital role in respiratory function.

204 views

Approximately 5-6% of the total CO2 produced by the body dissolves directly in the blood plasma. Another 70-90% is converted into bicarbonate ions, while the rest binds to hemoglobin. This efficient system ensures effective CO2 transport and regulation within the body.

FAQs & Answers

  1. What is the role of bicarbonate ions in CO2 transport? Bicarbonate ions play a crucial role in transporting CO2 from tissues to the lungs, making up 70-90% of the total CO2 in the blood.
  2. How does hemoglobin bind CO2? Hemoglobin binds to CO2 to transport it back to the lungs, ensuring efficient removal of carbon dioxide from the bloodstream.
  3. Why is CO2 regulation important in the body? Maintaining CO2 levels is vital for acid-base balance, respiratory function, and overall metabolic processes in the body.
  4. What happens when CO2 levels in the blood are too high? High CO2 levels can lead to respiratory acidosis, affecting oxygen delivery and overall bodily functions.
