What are blood types?That is the question we are going to be answering.There are four types of blood groups.They are A,B,AB,and O.You need to know your blood type because if you are in an accident and you need more blood.I don't know what my blood type is yet.It is important donated blood because if you get some other blood donated the former blood cells will die.
The O group are called universal doners because they can donate to any blood group,but they can only recieve blood from the O group.The AB group can recieve blood from any group,but can only donate to the AB grop.The B group can not donate to the A group.
Thats it,hope you found what you were looking for.
