Mark the incorrect statement regarding the transport of gas.
1. | About 97% of O2 is transported by RBC. |
2. | Nearly 20-25% of CO2 is transported by RBC. |
3. | Every 100 ml of deoxygenated blood deliver 4 ml of CO2 to the alveoli. |
4. | Every 100 ml of oxygenated blood deliver 20 ml of O2 to the body tissues |
Approximately seventy percent of carbon dioxide absorbed by the blood will be
transported to the lungs
1. as bicarbonate ions
2. in the form of dissolved gas molecules
3. by binding to RBC
