BSL Environmental Science Glossary - Haemoglobin definition

Definition: Red blood cells (which are recognisable to many because of their concave shape) contain a special protein called Haemoglobin, which is able to pick up oxygen molecules and circulate them via the bloodstream around the body. The process starts in the lungs - as we breathe in, our lungs fill with air, and red blood cells transport oxygen via this protein (haemoglobin).
