Question

A person with blood group is AB can donate blood to a person with blood group
A. A
B. B
C. AB
D. All of the above

Answer 1

Hint: The red blood cells have both A and B antigens, but the plasma does not contain anti-A or anti-B antibodies. The plasma contains both anti-A and anti-B antibodies, but the surface of the red blood cells does not contain any A or B antigens.

Complete answer:
The ABO blood group system classifies blood types according to the different types of antigens found in the red blood cells and antibodies in the plasma.

There are four ABO groups:
Group A: The surface of the red blood cells of group A individuals contains A antigen, and the plasma has anti-B antibody. Thus, anti-B antibodies would attack blood cells that contain B antigen.
Group B: The surface of the red blood cells group B individuals contains B antigen, and the plasma has anti-A antibody. Thus, anti-A antibodies would attack blood cells that contain an antigen.
Group AB: The red blood cells group AB individuals have both A and B antigens, but the plasma does not contain anti-A or anti-B antibodies. Thus, individuals with type AB can receive any ABO blood type.

Group O: The plasma of group O individuals contains both anti-A and anti-B antibodies, but the surface of the red blood cells does not contain any A or B antigens. Thus, a person with any ABO blood type can receive this type of blood.

Hence, the correct answer is option (C)

Note: The main components of blood are:
1.Red blood cells, which carry oxygen around the body
2.White blood cells, which play a crucial role in the immune system
3.Plasma, which is a yellowish liquid that contains proteins and salts
4.Platelets, which enable clotting
