Quizplus · Accepted Answer

The skin acts as both an innate defense mechanism and a first line of defense against pathogens. It is an innate defense mechanism because it is a natural, physical barrier that prevents the entry of pathogens. It is also considered a first line of defense because it is the initial barrier that pathogens encounter when trying to enter the body.
