Answer :
D) All of the above cells participate in nonspecific defense responses when your body is invaded by microbes.
What do you mean by nonspecific defense responses in the body?
The body's first line of defense against diseases is comprised of nonspecific defenses. They attempt to provide all-around immunity against a wide range of infections rather than being targeted at a specific pathogen. Nonspecific defenses include anatomic barriers like skin and mucous membranes, chemical defenses like lysozyme and hydrochloric acid, and other nonspecific defenses like inhibitors, interferons(IFNs), phagocytes, fever, and inflammation.
Natural killer (NK) cells are non-specific effector lymphocytes of the innate immune system that eliminate bodily cells that are malignant or harbor infectious pathogens. Natural killer cells destroy infected cells by injecting their granules containing toxic chemicals into them.
Macrophages are a type of white blood cell formed from the mature form of the monocyte that acts as scavenger cells. They detect and destroy pathogens through phagocytosis or "eating" of pathogens. Macrophages are present in many tissues such as the lymphoid tissues like the spleen and lymph nodes, as well as the liver. They serve as filters for trapping microbes, and other foreign particles that arrive through the blood or the lymph and them ingesting them.
Neutrophils are a type of White Blood Cell (WBC) or leukocyte that play an important role in mediating the body's nonspecific or innate immune responses against infectious microorganisms. Neutrophils are a type of granulocyte that contain secretory granules filled with enzymes that are released during infection. These granulocytes ingest and destroy microorganisms like bacteria and viruses.
Thus natural killer cells, macrophages, and neutrophils all participate in nonspecific defense response when the body is invaded by microbes.
Hence, D) All of the above cells participate in nonspecific defense responses when your body is invaded by microbes.
