Final answer:
Type O blood is called the universal donor as its absence of A and B antigens on the surface of erythrocytes prevents immune reactions, allowing donations to any blood type. Type AB blood individuals are known as the universal recipients because they do not produce antibodies that would cause a reaction to A or B antigens, enabling them to receive blood from any donor type.
Step-by-step explanation:
Erythrocytes from a person with type O blood can be given to any recipient in an emergency, which is why this blood type is called the universal donor. This is because type O blood erythrocytes do not have A or B antigens on their surfaces, preventing them from causing an antibody reaction when transfused into recipients with different blood types. People with type AB blood are considered universal recipients because they have both A and B antigens on the surface of their erythrocytes, and do not produce anti-A or anti-B antibodies, allowing them to receive blood from any ABO blood type. Additionally, those with AB+ blood are the most universal recipients as they can receive Rh+ and Rh- blood. However, it’s important to consider that any transfusion should ideally be matched to avoid complications, even though AB+ individuals can accept any blood in urgent situations.
A person with type AB blood is known as the universal recipient. This means that they can receive blood donations from individuals with any ABO blood type. This is because their own blood has both A and B antigens on the surface of their red blood cells, and therefore does not produce anti-A or anti-B antibodies. In addition, an Rh positive individual can receive both Rh positive and Rh negative blood.
