You have been taught that there are just 4 types of blood group A, B, AB and O. But ABO isn’t the only blood grouping system. There are currently 33 systems recognized by the International Society of Blood Transfusion There are blood groups called "Lutheran," "Duffy," "Hh/Bombay," "Ok," etc. From the attached image, oxygenated blood is the one with bright red, while dexoygenated blood is dark reddish.
