Answer» Correct Answer - A Nearly `20-25%` of `CO_(2)` is transported by `RBCs` whereas `70%` of it is carried as bicarbonate. About `7%` of `CO_(2)` is carried in a dissolved state through plasma. About `97%` of `O_(2)` is carried by `RBCs` in the blood. About `3%` of `O_(2)` is transported in a dissolved state through the plasma. |
