Corrected sentences:
- Antigens on red blood cells determine a person’s blood type.
- Antibodies in the blood attack foreign blood that is not compatible with those antigens.

Brief explanation:
- The main systems are ABO and Rh (D).
- Type A: A antigens on RBCs, anti-B antibodies in plasma.
- Type B: B antigens on RBCs, anti-A antibodies in plasma.
- Type AB: A and B antigens on RBCs, no anti-A/anti-B antibodies (can receive RBCs from any ABO type).
- Type O: no A/B antigens on RBCs, anti-A and anti-B antibodies in plasma (universal RBC donor).
- Rh+: has the D antigen; Rh− lacks it and can form anti-D antibodies after exposure.
- If a recipient’s antibodies recognize donor RBC antigens (or vice versa for plasma transfusion), the immune reaction can cause agglutination and hemolysis, which is why matching blood types is essential for safe transfusions and why Rh compatibility matters in pregnancy.
