Current Question (ID: 14409)

Question:

What is true about RBCs in humans?

Options:

1. They carry about 20-25 per cent of CO₂
2. They transport 99.5 per cent of O₂
3. They transport about 80 per cent oxygen only and the rest 20 per cent of it is transported in dissolved state in blood plasma
4. They do not carry CO₂ at all

Solution:

Nearly 20-25 per cent of CO₂ is transported by RBCs. It is caused by haemoglobin as carbamino haemoglobin. 70 per cent of CO₂ is carried as bicarbonates. About 97 per cent of O₂ is transported by RBCs in the blood. The remaining 3 per cent of O₂ is carried in dissolved state through the plasma.
