IMMUNE REACTION Meaning and
Definition
-
An immune reaction refers to the response of the immune system against foreign substances or antigens that invade the body, such as bacteria, viruses, or other pathogens. It is a complex biological process aimed at protecting the body from potential harm and maintaining its overall health.
When the immune system detects these foreign invaders, it triggers a series of reactions designed to eliminate or neutralize them. This involves the activation and coordination of various components of the immune system, including specialized cells, proteins, and chemical messengers.
The immune reaction involves two primary types of immune responses: the innate and adaptive immune responses. The innate immune response is the immediate, non-specific defense mechanism that provides a general defense against a wide range of pathogens. It includes physical barriers like the skin, as well as immune cells such as macrophages and neutrophils.
On the other hand, the adaptive immune response is a more specific and targeted immune reaction that develops over time. It involves the production of antibodies by B cells and the activation of T cells, which work together to recognize, attack, and remember specific antigens.
Overall, immune reactions are essential for maintaining the body's health and defending against potential harm. However, in certain situations, the immune system may overreact or malfunction, leading to various autoimmune disorders or allergies.

Etymology of IMMUNE REACTION
The word "immune" is derived from the Latin word "immunis", meaning "exempt" or "protected". The term "immunity" was first used in the late 16th century to describe exemption from legal obligations. In the context of biology and medicine, "immunity" refers to the body's ability to resist or protect itself against harmful foreign substances such as pathogens.
The word "reaction" originates from the Latin word "reactio", which means "to return" or "to act again". It was first used in the early 17th century to describe the response or response mechanism of a substance or organism to a stimulus or an interaction.
Therefore, the term "immune reaction" is a combination of "immune", indicating protection or resistance, and "reaction", indicating the response or response mechanism.
