An erythrocyte (or red blood cell) is one of the many different cells contained in the blood along with leukocytes and platelets. Every second, 2-3 million red blood cells are created[1]. These are made from the haemopoetic pluripotent stem cells in the bone marrow.

They are involved in the transport of oxygen around the body through haemoglobin. However, they also have a role in determining blood types.

There are four main blood groups: A, B, O and AB. 

These are caused by different antigens attached to the erythrocyte. They also have different sugars.

A blood group contains N-acetyl-galactosamine whilst B blood group contains just galactosamine.
