Question

A large proportion of oxygen is left unused in the human blood even after its uptake by the body tissues. This O2 (A) Helps in releasing more O2 to the epithelial tissues. (B) It is enough to keep oxyhaemoglobin saturation at 96 %. (C) Raise the p C O2 of blood to 75 mm of Hg. (D) Acts as a reserve during muscular exercise

A large portion of the oxygen is left unused in the human blood even after its uptake by the body tissues. This O2 acts as a reserve during muscular exercise. Tissues usually take up only 25% of the oxygen in the tissue and the rest 75% remain unused in the blood (venous).

Q. A large proportion of oxygen is left unused in the human blood even after its uptake by the body tissues. This O₂

Helps in releasing more $O_{2}$ to the epithelial tissues.

It is enough to keep oxyhaemoglobin saturation at $96%.$

Raise the $pC O_{2}$ of blood to 75 mm of Hg.

Helps in releasing more O2​ to the epithelial tissues.

It is enough to keep oxyhaemoglobin saturation at 96%.

Raise the pCO2​ of blood to 75 mm of Hg.
