Paper 1
The protein in red blood cells that binds and carries oxygen.
Revise: Cardiovascular System Structure and FunctionRed blood cells transport oxygen to tissues, including muscles used during physical activity. They contain haemoglobin, a protein that binds oxygen in the lungs and carries it in the blood.
Haemoglobin is found inside red blood cells. Oxygen combines with haemoglobin to form oxyhaemoglobin.
Do not say that haemoglobin carries only oxygen: it can also carry carbon dioxide.
