2
Q
What is responsible for Co2 tension (PCO2)?
A
The physically dissolved Co2
3
Q
What does PCo2 control?
A
The rate and direction of flow of O2
4
Q
Name effects of the chloride shift?
A
HT value increases, RBC volume increases
5
Q
Explain Bohr effect?
A
Increase in blood Co2 displaces O2 from the hemoglobin
6
Q
Explain Haldane effect?
A
Binding of oxygen with hemoglobin displaces Co2 from the blood
