What are the benefits of innate immunity?

Answer 1

Innate Immunity

Innate Immunity is a form of non specific host defense against invading bacteria. It is natural or "innate" to the host, depending, in part, on genetics. Innate defense mechanisms are contitutive to the host, meaning they are continually ready to respond to invasion and do not require a period of time for induction. The most important components of innate immunity are anatomical barriers, intact normal flora, tissue bactericides including complement, and ability to undergo inflammatory and phagocytic responses.

Innate immunity provides the first line of defense against invading bacteria. The skin and mucous membranes provide physical and chemical barriers to infection. The normal bacterial flora antagonize colonization of body surfaces by nonindigenous bacteria. The internal tissues invariably contain bactericidal substances. The most noteworthy antibacterial substance is the enzyme lysozyme, which is present in mucus and all bodily tissues and secretions. If these barriers are penetrated, the body contains cells that respond rapidly to the presence of the invader. These cells include macrophages and neutrophils that engulf foreign organisms and kill them. Bacterial invasion is also challenged by the activation of complement in blood and tissues and the incitement of an inflammatory process which has the tendency to focus both the innate and adaptive immune defenses on the site of invasion.

Answer 2

The innate immunity system is responsible for the "first line of defense" in your body. Any hostile bacteria that enter your system, will be fought of by this system. So a strong innate immunity makes the body less likely to get sick from initial infection.

Answer 3

To protect the body from harmful diseases.

Answer 4

The primary function of the human system is to fight intruders to the body and so avoid illness. For instance, white blood cells can gobble up bacteria.

Answer 5

To protect you from infections.
