What are antigens?
Antigens are marker present on some cells as marker
What are antibodies?
Blood protein
What is the function of antibodies?
Use in the body defense mechanism by clumping foreign substances, making it easy for the white blood cell to attack them
How do antibodies recognize foreign substances?
Specific antigen on foreign substances and attached to them
What will happen to the blood if antibodies clump up the foreign blood cells?
Clotting or agglutination
