What is Blood made of?

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 white blood cells fight infection.

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

example.

The plasma contains salts and various kinds of proteins.

•An adult human has about 4 –6 liters of blood circulating in the

body.

•Among other things, blood transports oxygen to various parts of 

the body.

•Blood consists of several types of cells floating around in a fluid

called plasma.

GROUPINGBlood 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
