Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A boy has type B-blood and his sister has B+ blood. Can the sister safely receive her brother’s blood in the event of a medical emergency?
A
YES
B
NO
Explanation: 

Detailed explanation-1: -The blood types must be compatible to avoid an ABO incompatibility reaction. For example: People with type A blood will react against type B or type AB blood. People with type B blood will react against type A or type AB blood.

Detailed explanation-2: -A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them.

Detailed explanation-3: -If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor’s blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood.

Detailed explanation-4: -A type blood has anti-B antibody in the plasma. B type blood has anti-A antibody in the plasma. AB has neither A nor B antibody in the plasma.
