One source told me:
A) phagocytes engulf the pathogen
B) lymphocytes produce antibodies that lock onto the pathogen so it cannot work.

Another said:
Lymphocytes produce antibodies that lock onto the antigens, then the phagocyte will engulf the pathogen.

What is the answer? And what are the 'two methods'?
Thank you!

You really just need to know that white blood cells produce antibodies. The white blood cells know which specific antibody to produce from recognising the antigen on a pathogen.

Lymphocytes produce antibodies.
Phagocytes engulf pathogens.

Both methods destroy/kill the pathogen.

Thanks, I think I've figured it all out now (I'm not the brightest in Bio!): the antibodies can bind to the pathogen and damage or kill it, or it can coat it, making them easier to digest by phagocytes

There are 3, this is how I remember it

Some white blood cells ingest pathogens , destroying them so they can't make you Ill

Some white blood cells produce antitoxins. These counteract the toxins produced by pathogens.

Some white blood cells produce antibodies. These target particular viruses or bacteria and destroy them( the antigens) your memory cells remember the particular pathogen and antibodies can be made a lot more quickly to destroy the pathogen.
