Haemoglobin (Hb) is a protein molecule found in red blood cells (RBCs) that plays a crucial role in the transportation of oxygen (O2) from the lungs to body tissues and the transfer of carbon dioxide (CO2) from the tissues to the lungs for exhalation. Hb binds reversibly with O2 in the lungs and releases it in the tissues that require oxygen for metabolic activities. Similarly, Hb binds with CO2 in the tissues and releases it in the lungs for removal through exhalation.
