Is phagocytosis a non specific immune response or a specific immune response?

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.

Why is phagocytosis non specific?
skin
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 is innate stimulus?
An innate response is a type of immune response, that is a quick and general (non-specific) attack for any invader that enters your body.
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
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
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 are immunostimulant drugs?
IMMUNOSTIMULANT 1. stimulating an immune response. 2. an agent that stimulates an immune response. Immunostimulators are substances (drugs and nutrients) that stimulate the immune system by inducing activation or increasing activity of any of its components. One notable example include granulocyte macrophage colony-stimulating factor, commercially available under Leukine name. There are two main categories of immunostimulators: Specific immunostimulators are those which provide antigenic specificity in immune response, such as vaccines or any antigen. Non-specific immunostimulators are those which act irrespective of antigenic specificity to augment immune response of other antigen or stimulate components of the immune system without antigenic specificity, such as adjuvants and non-specific immunostimulators. Many endogenous substances are non-specific immunostimulators. For example, female sex hormones are known to stimulate both adaptiveand innate immune responses. Some autoimmune diseases such as lupus erythematosus strike women preferentially, and their onset often coincides with puberty. Other hormones appear to regulate the immune system as well, most notably prolactin, growth hormone and vitamin D.
Is inflammation a type of non specific defense specific defense acquired defense or all of the above?
It is a non-specific Immune response as it does not change based on interaction with a pathogen and will activate regardless whether the pathogen in question has been encountered previously. Commonly referred to as being part of the "Second Line of Defence".
What system does HIV affecT?
HIV effects the non specific immune system that is Acquired Immune System.
How does the immune system function?
The immune system works in three ways: external, passive non-specific response: natural flora (eg- bacterium on skin), secretions (eg- mucus which prevents harmful bacteria contacting cell wall), surface barriers (eg-skin) internal, active non-specific response: White blood cells such as phagocytes and macrophages, complement proteins and interferons internal, active specific response: B lymphocytes, T lymphocytes
What is the difference between specific and nonspecific defense?
Fever
