The proteins found on the surface of RBCs that allow us to type blood as A, B, O or AB are called

• antigens

• antibodies

• aggluntates

• Rh factors

Answer explanation

The proteins on RBCs that determine blood type are called antigens.

What is the reaction between antigens and antibodies that allow you to determine blood type?

• clotting

• agglutination

• aggregation

• antibody production

Answer explanation

The reaction between antigens and antibodies that allows you to determine blood type is called agglutination. It is the process of clumping together of red blood cells in response to the presence of specific antibodies.

What is produced by your body in response to foreign antigens, such as the wrong type of blood?

• agglutinates

• clotting factors

• phagocytes

• antibodies

Answer explanation

When your body encounters foreign antigens, it produces antibodies as a response. Antibodies help to identify and neutralize these antigens, protecting your body from harm.
