Which fact suggests that most oxygen is transported from lungs to the tissue combined with hemoglobin rather than dissolved in blood plasma?
- O2 carrying capacity of whole blood is much higher than that of plasma and O2 content of blood leaving the lungs is greater than that of blood entering the lungs
- Hemoglobin can combine with O2
- Oxyhemoglobin can dissociate into hemoglobin and O2
- Increase in CO2 concentration decreases the O2 affinity of hemoglobin
Answer
(A) O 2 carrying capacity of whole blood is much higher than that of plasma and O 2 content of blood leaving the lungs is greater than that of blood entering the lungs
