A non specific event carried out by certain white blood cell types belonging to the innate (non-specific) immune system.

For example neutrophils and macrophages both carry out this process. Phagocytosis is the engulfing and digestion of foreign microorganisms and materials. The cells involved perform endocytosis of the material, surrounding it by a membrane as they take it in, where it is then usually destroyed by activation of chemicals inside the white cell.

What is the difference between the specific and nonspecific immune response?

Immunity provides protection against specific foreign antigens, displays memory, and it requires distinction between self and non self antigen.


What are the main differences between an inflammatory response and an immune response?

The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause.


What is the difference between the innate immune response and the acquired immune response?

The innate immune response is the body's first line of defense against pathogens and is non-specific, meaning it does not target specific pathogens. It includes physical barriers like skin and mucous membranes, as well as immune cells like macrophages and natural killer cells. The acquired immune response is more specialized and involves the activation of immune cells such as T and B lymphocytes that target specific pathogens based on memory from past exposures.


How many line of defenses does the body have?

The body has three lines of defense against pathogens: the first line is physical barriers like skin and mucous membranes, the second line is non-specific immune responses like inflammation and phagocytosis by white blood cells, and the third line is the adaptive immune response involving specialized cells and proteins to target specific pathogens.


Explain the difference between innate response and an acquired response?

The innate immune response is the body's immediate, non-specific defense mechanism against infections. It is always ready to respond to invaders. The acquired immune response is specific to a particular pathogen and involves the production of antibodies and memory cells for long-term protection. It takes time to develop but provides a targeted defense against specific pathogens.


What is non-specific immune responses?

Nonspecific immune response is the first and second line of defense when a foreign object tries to enter or enter the body. This response will attack anything (specific immune response will only attack certain infections) that it comes in contact with.Parts of nonspecific immune response are: Skin, Mucous membranes, Phagocytic (cells that eat foreign particles) cells, Antimicrobial proteins, and the inflammatory response.Inflammation-APEX


Why is phagocytosis non specific?

Phagocytosis is nonspecific because it does not rely on specific recognition of pathogens. Instead, phagocytes engulf and destroy a wide range of particles and microorganisms through the process of endocytosis. This allows the immune system to respond quickly to a variety of threats without needing to recognize each one individually.


What part of the immune system is a specific defense system?

The human immune system can be separated into three "lines of defense" 1) Tthe first line includes physical barriers-primarily the skin, and biochemical barriers-mucous, sweat, stomach acids, wax, oil ect. This is considered a non-specific response because the response is not different for different pathogens. 2) The second line includes the inflammatory response, natural killer cells, macrophages, and fever. This level of defense is also considered non-specific. 3) The third line includes the two specific defenses-your humoral or antibody mediated immune response and your cell mediated immune response. In both cases your body is responding to a particular antigen or infectious agent.


Are antibodies nonspecific?

Antibodies are non specific! That is why antibody testing does not signify anything specific except that an immune response is on progress. Processed flour will give you an immune response and show elevated liver enzymes that are typical during times of infection


ELISA test what is a meaning of non reactive?

In the context of an ELISA test, "non-reactive" means that no antibodies or antigens of interest were detected in the sample. This result indicates the absence of a specific immune response to the tested substance.


What is the difference between a specific and a nonspecific immune systems?

Nonspecific like the skin, mucous membranes, tears, mucus and the inflammatory response... are designed with and acidic surface that, for the most part, repels bacteria and are attributable to factors other than specific antibodies. They are often called innate immunities. Specific immunity has to do with how our lymphocytes (specialized white blood cells, such as B and T Cells) that can remember a specific virus or bacteria, and the next time it shows up, there's a whole welcoming party ready with lots of demolition gear to destroy the unwelcome guests.


What is the second line defense?

The second line of defence is the non specific, it includes antimicrobial proteins, phagocytes and other cells. - In this state to inhibit spread of invader through out the body. -Inflamation, is its hallmark and most important mechanism.
