Which of the following are TRUE of lymph nodes? They cause cancer cells to metastasize T/F? They act as filters to clean the lymph, preventing unwanted substances from being delivered to the blood T/F? They offer a place for lymphocytes to become activated and mount an attack against antigens T/F? They are the primary site to cleanse the blood of aged erythrocytes T/F?

Once the antigen presenting cell delivers the message about the identity of the specific pathogen to the adaptive immune system, what is the mechanism of lymphocyte activation to make sure lymphocytes target that specific pathogen or toxin (Specificity)? Why does this process create a slow response during the first exposure of a pathogen?
