Vedclass · Answer

(A) $RBCs$ (Red Blood Cells) play a crucial role in the transport of respiratory gases.$1$. Oxygen Transport: About $97$ percent of $O_2$ is transported by $RBCs$ in the blood,bound to hemoglobin. The remaining $3$ percent of $O_2$ is carried in a dissolved state through the blood plasma.$2$. Carbon Dioxide Transport: Nearly $20-25$ percent of $CO_2$ is transported by $RBCs$ (as carbaminohemoglobin). About $70$ percent of $CO_2$ is carried as bicarbonate ions $(HCO_3^-)$,and approximately $7$ percent of $CO_2$ is carried in a dissolved state through the plasma.Therefore,the statement that $RBCs$ carry about $20-25$ percent of $CO_2$ is correct.
