Refer to the given diagrammatic representation of the transportation of oxygen and carbon dioxide in the blood. P, Q, R, S and T represent percentage of both gases in different forms. Select the correct option for `P-T`.

Options

A. a) `{:("P",Q,R,S,T),(23%,70%,7%,93%,7%):}`
B. b) `{:("P",Q,R,S,T),(7%,23%,70%,3%,97%):}`
C. c) `{:("P",Q,R,S,T),(7%,23%,70%,97%,3%):}`
D. d) `{:("P",Q,R,S,T),(70%,7%,23%,97%,3%):}`

Answer

B

Explanation

Blood is the medium of transport for `O_(2)` and `CO_(2)`. About `97%` of `O_(2)` is transported by RBCs in the blood. The remaining `3%` of `O_(2)` is carried in a dissolved state through the plasma. 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.
