Write the types of blood with examples.
Answers
Explanation:
There are 4 main blood groups defined by the ABO system:
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma.
blood group B – has B antigens with anti-A antibodies in the plasma.
blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
Answer:
The ABO blood system has four main types:
Type A: This blood type has a marker known as A.
Type B: This blood type has a marker known as B.
Type AB: This blood type has both A and B markers.
Type O: This blood type has neither A or B markers.
Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor).
So, there are eight possible blood types
O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.
O positive. This blood type doesn't have A or B markers, but it does have Rh factor. O positive blood is one of the two most common blood types (the other being A positive).
A negative. This blood type has A marker only.
A positive. This blood type has A marker and Rh factor, but not B marker. Along with O positive, it's one of the two most common blood types.
B negative. This blood type has B marker only.
B positive. This blood type has B marker and Rh factor, but not A marker.
AB negative. This blood type has A and B markers, but not Rh factor.
AB positive. This blood type has all three types of markers — A, B, and Rh factor.
