Which immune response involves lymphocytes?

Acquired immunity involves lymphocytes, which are a type of white blood cell crucial for the adaptive immune system's function. This branch of the immune response is characterized by its ability to recognize specific pathogens and remember them for future encounters, leading to a more rapid and effective response upon re-exposure.

Two main types of lymphocytes play significant roles in acquired immunity: B cells and T cells. B cells are responsible for producing antibodies that target specific antigens, leading to the neutralization and destruction of pathogens. T cells, on the other hand, perform various functions, including directly killing infected cells and coordinating the immune response by signaling other cells.

In contrast, innate immunity, the inflammatory response, and phagocytosis are components of the non-specific immune response. Innate immunity constitutes the body's first line of defense against pathogens and does not involve the specificity associated with lymphocytes. The inflammatory response is a generalized reaction to injury or infection, characterized by increased blood flow and immune cell infiltration, and also does not specifically involve lymphocyte activation. Phagocytosis refers to the process by which certain immune cells, such as macrophages and neutrophils, engulf and digest pathogens or debris, further highlighting its role in the innate immunity rather than the adaptive response
