Answer:
Step-by-step explanation:
Type A: Red blood cells possess two different glycoprotein antigen on their surface. They are named as A antigen and B antigen. The rbc which possess A antigen on their surface are know as A group. The RH systems says that rbc has one more antigen beside A and B antigen and named that new antigen as Rh antigen. The person who has Rh antigen are termed as Rh positive. The person who doesnt consist Rh antigen are termed as Rh negative. So A positive means the human Rbc consist A and Rh antigen on their surface. A negative means human Rbc consist only A antigen on their surface.
Type B(+) particularities:
The red blood cells of B+ people are coated withantigens called “type B” on their surface. Therefore, these people can only donate blood to people in groups B and AB, who do not have anti-B antibodies.
B+ red blood cells can only be transfused to rhesus positive people: AB positive (AB+) and B positive (B+).
Type B blood also contains anti-A antibodies, so B+ can receive red blood cells of blood groups O and B, all rhesus combined.
Type (B-) particularities:
Like B+ people, B- people have type B antigens on the surface of their red blood cells. Their blood can therefore only be transfused to people in groups B and AB, who do not have anti-A antibodies.
On the other hand, B- people can give both rhesus groups B and AB (B+, B-, AB+, AB-).
Finally, they can receive red blood cells of the O negative (O-) and B negative (B-) blood groups.
I really hope this gives some clearance
