Antibody

Antibodies are specialized proteins that target specific antigens, such as viruses or bacteria. They are produced by B lymphocytes, a type of white blood cell. Antibodies function by either aiding phagocytes in identifying and ingesting invaders or by directly attacking the antigens.

What is the role of antibodies in relation to antigens?

• They attack all types of antigens indiscriminately.

• They are effective against only one specific antigen.

• They are harmful agents themselves.

• They are produced by red blood cells.

Which type of cells are responsible for producing antibodies?

• T lymphocytes

• Red blood cells

• B lymphocytes

• Platelets

How do antibodies assist phagocytes?

• By destroying phagocytes

• By transforming into phagocytes

• By identifying and ingesting invaders

• By producing more phagocytes

What is one direct action antibodies can take against invaders?

• They can transform into invaders.

• They can become invaders themselves.

• They can directly attack the invaders.

• They can ignore the invaders.

What is the primary function of phagocytes in the immune response?

• To transform into antibodies

• To identify and ingest invaders

• To produce antibodies

• To attack antibodies
