Question

The skin helps to keep pathogens out of the body by

Answer 1

I think A would be the correct answer. Your skin does not produce white blood cells, your body produces white blood cells and releases them into your blood system. Your skin does not also make T cells or antibodies. This all happens internally and they stay internal. Your body can absorb things like histamine, however I’m not sure how this would help to keep pathogens out of the body.
