Question

Are there any parts of the human body that get oxygen directly from the air and not from the blood?​

Answer 1

Hi, not that I’m aware of as the haemoglobin always becomes oxyhaemoglobin and then deoxyhaemoglobin after o2 dissociates from haemoglobin as the affinity between o2 and haemoglobin is low… in other terms… all o2 we get comes from the blood.
