People who have migrated from the planes to an area adjoining Rohtang pass about six months backA. have more RBCs and their haemoglobin has a lower binding affinity to ` O_(2)`B. are not physcially fit to play games like footballC. suffer from altitude sickness with symptoms like nausea, fatigue, etc.D. |
|
Answer» Correct Answer - A As a person moves up a hill the ` pO_(2)` and total atmospheric pressure decreases. Decrease in `pO_(2)` due to increasing altidue , stimulates the JG cells of kidney to secrete erythrpoetin hromone, increasing the number of RBCs (polycythemia) to compensate the supply of `O_(2)`. At higher atitude haemoglobin has lower binding affinity to `O_(2)` , because the primary factor responsible for binding is `pO_(2)` . which decreases at higher altitude. |

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`. A. `{:("P",Q,R,S,T),(23%,70%,7%,93%,7%):}`B. `{:("P",Q,R,S,T),(7%,23%,70%,3%,97%):}`C. `{:("P",Q,R,S,T),(7%,23%,70%,97%,3%):}`D. `{:("P",Q,R,S,T),(70%,7%,23%,97%,3%):}` |
|
Answer» Correct Answer - B 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. |
