one gives the other receives
The four blood types are A, B, AB, and O. Blood type O is the universal donor because it does not have A or B antigens on its red blood cells. Blood type AB is the universal recipient as it does not have antibodies against A or B antigens.
Type A preferred donor refers to a donor who has the same blood type as the recipient, making them the best match for a blood or organ donation. Permissible donors are those who have compatible blood types with the recipient, while incompatible donors have blood types that would cause a reaction if transplanted.
The test that determines the compatibility of donor and recipient blood is called a blood typing test. This test identifies the specific blood type of an individual, focusing on the ABO blood group system and the Rh factor.
Compatibility testing involves mixing donor red blood cells (RBCs) with recipient serum to check for agglutination. If agglutination occurs, it indicates incompatibility between the donor RBCs and recipient serum, suggesting a mismatch that could lead to a transfusion reaction. Testing is crucial to ensure safe blood transfusions.
O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
The main test to determine compatibility between donor and recipient blood is the ABO blood group and Rh factor testing. Additionally, crossmatching is done to further ensure compatibility. This involves mixing a sample of the donor's blood with the recipient's blood to see if there are any reactions.

A beating-heart transplant is a heart transplant operation in which the donor heart is kept full of blood and continues to beat in a machine between donor and recipient.
The recipient's immune system will detect the difference between the two sets of antigen and start a rejection response to kill the donated tissue.
crossmatching
If they are not exact as possible, the person receiving the blood or tissue or organ will reject it as foreign (doesn't belong).
If the recipient has type B blood, they can receive either type B or type O blood. If the donor blood is type B, then the recipient can be either type B or type AB

Yes, people with type O blood can donate to anyone.
