If anti-B antibodies (from someone who is blood type A or AB) are mixed with group B red cells, agglutination or clumping of red cells will occur due to a reaction between the antibodies and the B antigen on the red cells. This can lead to transfusion reactions if incompatible blood is transfused, causing harm to the recipient.

Why you can give patients with group A blood with group O?
Group O blood is considered the universal donor because it lacks A and B antigens on the red blood cells, reducing the risk of a transfusion reaction in patients with group A blood who have anti-B antibodies. Group O red blood cells are less likely to be attacked by antibodies in the recipient's blood. However, it is important to consider Rh factor compatibility as well.
Why the antibodies anti A and anti B in blood group O do not destroy cells of blood group A or B destroy?
Antibodies anti A and anti B in blood group O do not destroy cells of blood group A or B because individuals with blood group O do not have A or B antigens on their red blood cells. Therefore, they do not recognize A or B antigens as foreign and do not produce antibodies against them. This prevents the destruction of blood cells of other blood groups.
Why blood group o should not receive blood from other groups?
Blood group O individuals are considered universal donors because their blood cells do not have A or B antigens on their surface. If blood group O receives blood from other groups, there is a risk of a transfusion reaction where the recipient's immune system may attack the donor's blood cells which have A or B antigens. This can lead to serious complications or even death.
Will the B antibody in the plasma donor blood group A agglutinate the A antigen of the AB recipient and Why?
Yes. A person with blood group antibody B can not donate blood to another person with group A because it will agglutinates as they blood group A can only be donated to to a person with blood group A. Even though you donate whole blood, all of it is not given unless you both have the exact blood type. A person with A type (who has B antibodies in their plasma) will only donate their cells. No antibodies will be given. So AB can be given A but without the plasma which has the antibodies.
Which White blood cells that activate plasma cells?
Helper T cells (Th2 cells) play a role in activating plasma cells, which are responsible for producing antibodies. Helper T cells release cytokines that stimulate B cells to differentiate into plasma cells and produce specific antibodies against pathogens.
Why you can give patients with group A blood with group O?
Group O blood is considered the universal donor because it lacks A and B antigens on the red blood cells, reducing the risk of a transfusion reaction in patients with group A blood who have anti-B antibodies. Group O red blood cells are less likely to be attacked by antibodies in the recipient's blood. However, it is important to consider Rh factor compatibility as well.
What are blood groups and what is their importance?
Blood type is determined by antibodies and antigens present in red blood cells antibodies A and B for blood group A and B, when there's no antibodies it is group AB, when both antibodies A and B is present then it is group O
Why the antibodies anti A and anti B in blood group O do not destroy cells of blood group A or B destroy?
Antibodies anti A and anti B in blood group O do not destroy cells of blood group A or B because individuals with blood group O do not have A or B antigens on their red blood cells. Therefore, they do not recognize A or B antigens as foreign and do not produce antibodies against them. This prevents the destruction of blood cells of other blood groups.
What are the 4 kinds of blood?
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). 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.
A person with type A blood has antibodies to?
Type A blood will produce antibodies against B antigens.
How can the blood group O transfer their blood to the blood group A though the former has an Antibody A?
Because the blood cells from the O-group donor have no antigens which would react with the A-antibodies in the recipient.
What type of white blood cells make antibodies?
There are two types of white blood cell. The kind which secrete antibodies to kill microbes are called lymphocytes. The other type, which engulf microorganisms, are called phagocytes.*Specifically, the type of lymphocyte (white blood cell) that produces antibodies would be plasma cells. After a B cell (a type of lymphocyte) undergoes clonal selection, the result is the formation of a clone of B cells that consists of plasma cells and memory B cells. Plasma cells secrete antibodies and memory B cells do not secrete antibodies.
What group of proteins mark foreign invaders and attract phagocytes to destroy them?
B cells release antibodies that attach to foreign invaders and mark them for destruction by phagocytes.
What is reverse blood group testing?
Blood typing procedure wherein the antibodies are determined rather than the Antigen (Direct Typing). Uses pool A cells and pool B cells.
Why blood group o should not receive blood from other groups?
Blood group O individuals are considered universal donors because their blood cells do not have A or B antigens on their surface. If blood group O receives blood from other groups, there is a risk of a transfusion reaction where the recipient's immune system may attack the donor's blood cells which have A or B antigens. This can lead to serious complications or even death.
Will the B antibody in the plasma donor blood group A agglutinate the A antigen of the AB recipient and Why?
Yes. A person with blood group antibody B can not donate blood to another person with group A because it will agglutinates as they blood group A can only be donated to to a person with blood group A. Even though you donate whole blood, all of it is not given unless you both have the exact blood type. A person with A type (who has B antibodies in their plasma) will only donate their cells. No antibodies will be given. So AB can be given A but without the plasma which has the antibodies.
What kind of antibodies does type AB have?
Since that person has anti-B antibodies, then A antigens are present in her red blood cells. Since that person doesnt have anti-A antibodies, then there are no B antigens present, which means the person has A type blood.
