Question

The circulation of blood in human body supplies O2 and releases CO2 The concentration of O2 and CO2 is variable but on an average, 100 ml blood contains 0.02 g of O2 and 0.08 g of CO2 The volume of O2 and CO2 at 1 atm and at body temperature 37° C, assuming 10 L blood in human body, is (A) 2 L, 4 L (B) 1.5 L, 4.5 L (C) 1.59 L, 4.62 L (D) 3.82 L, 4.62 L

∵ 100 ml blood has 0.02 g O2 and 0.08 g CO2 ∴ 10,000 ml blood has 2 g O2 and 8 g CO2 Using PV= nRT for O2, 1× Vo2=(2/32)×0.0821×310 ⇒ Vo2=1.59 Litre for CO2, 1× VCO2 =(8/44)×0.0821×310 ⇒ Vo2=4.62 Litre

$2 L, 4 L$

$1.5 L, 4.5 L$

$1.59 L, 4.62 L$

$3.82 L, 4.62 L$

∵ 100ml blood has 0.02g O2​ and 0.08gCO2​ ∴ 10,000ml blood has 2gO2​ and 8gCO2​ Using PV=nRT for O2​, 1×Vo2​​=322​×0.0821×310 ⇒Vo2​​=1.59 Litre for CO2​,1×VCO2​​=448​×0.0821×310 ⇒Vo2​​=4.62 Litre
