5 Questions
What is the role of bicarbonate ions in CO2 transport?
Bicarbonate ions are formed in the blood and transported to the lungs, where they combine with hydrogen ions to release CO2 and water.
What is the difference in partial pressure of CO2 between tissues and blood?
The partial pressure of CO2 is higher in tissues compared to the blood.
How is CO2 transported from tissues to the blood?
CO2 diffuses from the tissues into the blood.
How is CO2 transported from the blood to the lungs?
Bicarbonate ions formed in the blood are transported to the lungs.
What happens to CO2 in the lungs?
In the lungs, bicarbonate ions combine with hydrogen ions to release CO2 and water, which can be exhaled.
Test your knowledge on CO2 transport in the body and understand how it is dependent on partial pressure. Learn about the role of bicarbonate ions and the reverse process that occurs in the lungs.
