What is true about RBCs in humans? |
|
|
a) |
They carry about 20-25 per cent of carbon dioxide |
|
b) |
They transport 99.5 per cent of oxygen |
|
c) |
They transport about 80 per cent oxygen only and the rest 20 per cent of it is transported in dissolved state in blood plasma |
|
d) |
They do not carry carbon dioxide at all |

(a)
Nearly 20-25% of carbon dioxide is transported by RBCs. It is carried by haemoglobin as carbamino haemoglobin. 70% of carbon dioxide is carried as bicarbonates.
About 97% of oxygen is transported by RBCs in the blood. The remaining 3% of oxygen is carried in dissolved state through the plasma.
