What are blood types?

Back

Blood types are classifications of blood based on the presence or absence of specific antigens and antibodies in the blood. The main blood types are A, B, AB, and O.

Front

What antigens are present in blood type A?

Back

Blood type A has A antigens on the surface of red blood cells and B antibodies in the plasma.

Front

What antigens are present in blood type B?

Back

Blood type B has B antigens on the surface of red blood cells and A antibodies in the plasma.

Front

What antigens are present in blood type AB?

Back

Blood type AB has both A and B antigens on the surface of red blood cells and no A or B antibodies in the plasma.

Front

What antigens are present in blood type O?

Back

Blood type O has no A or B antigens on the surface of red blood cells but has both A and B antibodies in the plasma.

Front

What is the universal donor blood type?

Back

The universal donor blood type is O, as it has no A or B antigens that could trigger an immune response in recipients.

Front

What is the universal recipient blood type?

Back

The universal recipient blood type is AB, as it has both A and B antigens and can accept blood from any type.

Front

What is codominance in relation to blood types?

Back

Codominance is a genetic pattern where both alleles are expressed equally, as seen in blood type AB, where both A and B antigens are present.

Front

Where are antibodies located in the blood?

Back

Antibodies are located in the plasma of the blood.

Front

What is the role of antigens in blood types?

Back

Antigens are substances on the surface of red blood cells that determine blood type and can trigger an immune response if foreign blood is introduced.
