What is true about RBC s in humans?

Options

(a) They carry about 20-25 per cent of CO₂
(b) They transport 99.5 per cent of O₂
(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 CO₂ at all

Correct Answer:

They carry about 20-25 per cent of CO₂

Explanation:

Blood transports oxygen from respiratory organs to the tissue cells and also transports CO₂ from the tissue cells to the respiratory membrane. About 97% of oxygen is transported by RBC s in the blood while the remaining three percent of oxygen is carried in a dissolved state through plasma. Nearly 20-25% of CO₂ is transported by RBC s whereas 70% is carried as bicarbonate. About 7% of CO₂ is carried in dissolved state through plasma.
