NATURAL IMMUNITIES Meaning and
Definition
-
Natural immunities refer to the inherent and innate defense mechanisms possessed by an organism that provide resistance against infectious diseases. These immunities are typically present from birth or acquired through genetic inheritance. They act as a barrier to prevent or control the entry and spread of pathogens within the body.
There are various types of natural immunities that work together to protect the organism. Physical barriers, such as the skin and mucous membranes, form the first line of defense by preventing the entry of harmful microorganisms. Chemical barriers, including enzymes found in body secretions, acidic pH of certain body fluids, and antimicrobial substances, exhibit antimicrobial properties and inhibit the growth of pathogens.
Another component of natural immunities involves the immune system. The immune response consists of specialized cells, such as phagocytes and lymphocytes, that recognize and destroy foreign invaders. Phagocytes engulf and digest pathogens, while lymphocytes produce specific antibodies or directly attack infected cells. These immune cells have the ability to recognize self from non-self, distinguishing between the body's own cells and foreign substances.
Natural immunities are crucial for maintaining overall health and are responsible for protecting individuals against a wide range of infectious diseases. However, it is important to note that natural immunities are not specific to a particular pathogen. Instead, they provide a general defense mechanism that can be enhanced or supplemented by adaptive or acquired immunity, which is targeted against specific pathogens and developed over time through exposure or immunization.

Etymology of NATURAL IMMUNITIES
The term "natural immunities" is derived from two separate words: "natural" and "immunities".
1. Natural: The word "natural" originates from the Latin word "naturalis", which means "by birth". It comes from the noun "natura", which means "birth, nature, quality". In English, "natural" refers to something existing in or caused by nature, not artificial or man-made. It can also refer to inherent qualities or tendencies.
2. Immunities: "Immunities" is the plural form of the noun "immunity", which is derived from the Latin word "immunitas". It comes from the prefix "im-" meaning "without" and the word "munis" meaning "duty or service". Thus, "immunitas" refers to being exempt from a service or duty.
