Blood groups

Imagine you’ve been involved in an accident. You’re bleeding and are rushed to the hospital. Thankfully you’re given a blood transfusion, to replace your lost blood. But you can’t just have blood from any old donor... In fact, when Doctors first attempted blood transfusions in the 17th century they were unsuccessful and patients died. How do medical teams now know what blood to give to which patient? Different people have different blood types or groups. You can be either: O, B, A or AB. If you’re given a blood transfusion, you must have blood which is compatible with your blood type. In this video, you will learn a bit more about Blood Groups.
