What is the role of partial pressure of CO2 in the transport of CO2 in the body?
What is the role of partial pressure of CO2 in the transport of CO2 in the body?
The partial pressure of CO2 determines the direction of diffusion and facilitates the transport of CO2 between tissues and blood.
How is CO2 transported from tissues to the lungs?
How is CO2 transported from tissues to the lungs?
CO2 is transported from tissues to the lungs by diffusing into the blood, where it reacts with water to form bicarbonate ions and is then transported as bicarbonate ions.
What happens to bicarbonate ions in the lungs during the CO2 transport process?
What happens to bicarbonate ions in the lungs during the CO2 transport process?
In the lungs, bicarbonate ions combine with hydrogen ions to release carbon dioxide and water.
