IMMUNOLOGICAL SURVEILLANCES Meaning and
Definition
-
Immunological surveillance refers to the continuous and vigilant monitoring process carried out by the immune system to detect and eliminate abnormal or foreign substances within the body, such as pathogens, cancer cells, or mutated cells.
The immune system consists of various components and mechanisms that work together to ensure immunological surveillance. These include specialized cells like white blood cells, antibodies, and other immune molecules that recognize and target foreign or abnormal cells. The process begins when the immune system recognizes specific antigens on these cells, which trigger an immune response.
During immunological surveillance, immune cells constantly survey the body for any signs of abnormalities. This surveillance occurs in various tissues and organs, including the blood, lymphoid organs (such as lymph nodes and spleen), and mucosal surfaces. Immune cells move throughout these sites, seeking out and destroying any cells that display foreign antigens or exhibit abnormal behavior, such as cancer cells.
Immunological surveillance is a crucial mechanism that helps to protect the body from various threats, including infections and the development of tumors. It plays a critical role in identifying and eliminating cells that pose a risk to the overall health and integrity of the body.
In summary, immunological surveillance is the ongoing process through which the immune system continuously monitors the body for foreign or abnormal cells and substances, initiating appropriate immune responses to eliminate them and maintain overall health.

Etymology of IMMUNOLOGICAL SURVEILLANCES
The word "immunological surveillance" is derived from the combination of two distinct terms: "immunological" and "surveillance".
1. Immunological: The term "immunological" is derived from the word "immune", which comes from the Latin word "immunis" meaning "exempt or free from". It refers to the body's immune system and its ability to defend against pathogens and foreign substances to maintain health.
2. Surveillance: The word "surveillance" originates from the French word "surveiller", which means to "watch over". It consists of the prefix "sur-" (meaning "over" or "above") and the verb "veiller" (meaning "to watch"). The term refers to the act of closely monitoring or observing a particular area or situation.
