A large proportion of oxygen is left unused the human blood even after its
uptake by the body tissues. This O2
1. Helps in releasing more O2 to the epithelium tissues
2. Acts as a reserve during muscular exercise
3. Raises the pCO2 of blood to 75 mm of Hg
4 Is enough to keep oxyhaemoglobin saturation at 96%
