Answer» Correct Answer - D Blood is the medium of transport for `O_(2)" and "CO_(2)`. About 97 per cent of `O_(2)` is transported by RBCs in the blood. The remaining 3 per cent of `O_(2)` is carried in a dissolved state through the plasma. Nearly 20-25 per cent of `CO_(2)` is transported by RBC8 whereas 70 per cent of it is carried as bicarbonate (Sodium bicarbonate). About 7 per cent of `CO_(2)` is carried in a dissolved state through plasma. |
