When the Body Launches a Nonspecific Immune Response, _______

Question

When the body launches a nonspecific immune response, _______.
A) lymphocytes produce dendritic cells
B) natural killer cells secrete antibodies
C) phagocytes form clones that develop into T cells
D) neutrophils and macrophages ingest bacteria by phagocytosis

Accepted Answer

Neutrophils and macrophages are phagocytes that can engulf and digest microorganisms through the process of phagocytosis. This is a key mechanism of the nonspecific immune response in which the body's cells and tissues work together to protect against pathogens. Option A is incorrect as dendritic cells are antigen-presenting cells, not produced by lymphocytes. Option B is incorrect as natural killer cells are not known for secreting antibodies, rather they are important in innate immunity against virus-infected cells and cancer cells. Option C is incorrect as phagocytes and T cells are two distinct types of cells with different functions in the immune system.
