the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
they choose one: a. can activate complement. b. are primed to proliferate and attack the invader. c. can produce antibodies against the pathogen. d. can activate cells of the adaptive immune system.
Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.
