Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following cells participate in nonspecific defense responses when your body is invaded by microbes?
A
natural killer cells
B
macrophages
C
neutrophils
D
all of the above
E
none of the above
Explanation: 

Detailed explanation-1: -The neutrophils, basophils, eosinophils, and monocytes are all part of a non-specific defense system. This means that the cells are capable of destroying a large variety of bacterial or viral invaders or cellular debris resulting from tissue damage, without specific recognition of which bacterium or viral invader.

Detailed explanation-2: -Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.

Detailed explanation-3: -Phagocytes are the component of non-specific immune response and kill the pathogens that invade the body.

Detailed explanation-4: -Inflammation. Inflammation is a nonspecific mechanism generated by the host in response to an infectious, physical, or chemical injury with recruitment of peripheral blood leukocytes and plasma proteins to the site of injury or tissue damage.
