Blood Groups and Types

Experiments with blood transfusions, the transfer of blood or blood components into a person's blood stream, have been carried out for hundreds of years. Mixing blood from two individuals can lead to blood clumping or concatenation. The clumped red cells can crack and cause toxic reactions which can have very harmful consequences.

Our Blood constitutes :

Plasma(liquid part)

E- nutrientsrythrocytes (or red blood cells)

Leukocytes (or white blood cells)

Thrombocytes (or platelets)

Plasma which is made of : water, proteins, dissolved nutrients, carbon dioxide, urea, lactic acid, serum albumin, blood clotting factors, antibodes and electrolytes! (But mostly water).

The white blood cells fight infection

The red blood cells contain hemoglobin, a protein that binds oxygen. Red blood cells transport oxygen to, and remove carbon dioxide from, the body tissues.

The platelets help the blood to clot, if you get a wound for example.

Blood Group Types

Blood group A : If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.

Blood group B : If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.

Blood group AB : If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.

Blood group 0 : If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.

Antigens and Antibodies

Antigens are "coats" that germ wear that are recognised by the immune system. When the immune system (WBC) recognises the antigen it produces a protein called an antibody that attaches to the antigen and thus destroys
