Examples include tears, mucous, and stomach acid. Cellular defenses of the innate immune response are non-specific. These cellular defenses identify pathogens and substances that are potentially dangerous and takes steps to neutralize or destroy them.
Which of the following is are involved in non specific innate immunity?
Explanation: The innate immune system is the non-specific immune system that you are born with. Cells of the innate immune system include mast cells, macrophages, neutrophils (and other white cells), natural killer cells, and complement (a group of proteins found in the blood).
How many internal immune system defenses are there?
The system can be divided into two types of defense systems: the innate immune system, which is nonspecific toward a particular kind of pathogen, and the adaptive immune system, which is specific (Figure 1).

Which of the following is/are the most specific internal defense against disease? T cells are a part of the adaptive (specific) defenses against disease. They are involved in cell-mediated immunity as they defend the body against specific pathogens.
What are 2 types of nonspecific immunity?
there are two types: nonspecific, innate immunity and specific, acquired immunity. Innate immunity, with which an organism is born, involves protective factors, such as interferon, and cells, such as macrophages, granulocytes, and natural killer cells, and its action does not depend on prior exposure to a pathogen.
