Innate immune system The innate immune system, also known as the nonspecific immune system, is an important subsystem of the overall immune system that comprises the cells and mechanisms that defend the host from infection by other organisms.he complement system is a biochemical cascade of the immune system that helps, or “complements”, the ability of antibodies to clear pathogens or mark them for destruction by other cells.

- Nonspecific, non-acquired defense is found in all animals and is effective in destroying invading microbes. However it is most effective outside of the host cells. The specific defenses of acquired immunity can, not only recognize specific pathogens, but also recognize cells that have been infected by those pathogens.The high degree of specificity of the vertebrate immune system requires many different kinds of cells.You must have javascript enabled to view this website.onspecific, non-acquired defense is found in all animals and is effective in destroying invading microbes.

The Human Immune System and Infectious Disease Two types of white blood cells called lymphocytes are vital to the specific immune response. Lymphocytes are produced in the bone marrow, and mature into one of several subtypes. The two most common are T cells and B cells. An antigen is a foreign material that triggers a response from T and B cells.The human body has B and T cells specific to millions of different antigens. We usually think of antigens as part of microbes, but antigens can be present in other settings.on-Specific (Innate) Immunity. The human immune system has two levels of immunity: specific and non-specific immunity. Through non-specific immunity, also called innate immunity, the human body protects itself against foreign material that is perceived to be harmful.

How many pounds do 500 pieces of paper weigh? This measures 297mm x 210 mm. It comes in packs of 500 sheets. So, a pack would 'measure' 0.297 x 0.210 x 500 sq metres = 31.185sq m. At 80 grams per sq m this equates to a total weight of 2494.8 grams ~ almost 2.5 kilos.his measures 297mm x 210 mm. It comes in packs of 500 sheets.

secondary immune response The response of the immune system to an antigen ( immunogen ) that leads to the condition of induced sensitivity ; the immune response to the initial antigenic exposure ( primary immune response ) is detectable , as a rule , only after a lag period of from several days to 2 weeks ; the immune response to a subsequent stimulus ( secondary immune ...

Introduction to Immunology Tutorial Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen.Adaptive immunity also includes a memory that makes future responses against a specific antigen more efficient.hese mechanisms include physical barriers such as skin, chemicals in the blood, and immune system cells that attack foreign cells in the body. The innate immune response is activated by chemical properties of the antigen.

What are three specific examples of non-specific immunity? INNATE (NON-SPECIFIC) IMMUNITY. The elements of the innate (non-specific) immune system (Table 2) include anatomical barriers, secretory molecules and cellular components. Among the mechanical anatomical barriers are the skin and internal epithelial layers, the movement of the intestines and the oscillation of broncho-pulmonary cilia.

Immunologic Tolerance Anergy An absence of cell-mediated immune reaction in supposedly sensitized animals or individuals. Anergy is a term in immunobiology that describes a lack of reaction by the body's defense mechanisms to foreign substances, and consists of a direct induction of peripheral lymphocyte tolerance.

Nonspecific Defense Antibodies are part of the body's specific immune response. Some immune cells and cells that are infected with viruses produce another set of proteins called interferons. Interferons send a warning to nearby cells.n animals, there are two types of defenses against foreign invaders: specific and nonspecific. Specific immune responses can distinguish among different invaders. The response is different for each invader. With nonspecific defenses, the protection is always the same, no matter what the invader may be.

- Mechanism[edit] Allergies are an abnormal immune reaction. The human immune system is designed to protect the body from potential harm and in people who have allergies the immune system will react to allergens (substances that trigger an immune response).

A normal immune system reacts when the body identifies a foreign protein such as proteins on the outside of bacteria. This foreign material which invokes the immune response is called an antigen.mail Article. A hypersensitive immune system is one which overreacts to a stimulus.

Immune Response The body does not usually start an immune response against its own antigens because cells that recognize self-antigens are deleted or inactivated. This concept is called self-tolerance and is a key characteristic that defines immune responses. A second characteristic is specificity.

Nonspecific Defense Whether the mechanism is as complex as fever and inflammation or as simple as physical barriers and phagocytosis, all nonspecific defenses provide the body with general protection against foreign invaders. SEE ALSO Antibody ; Blood ; Endocytosis ; Immune Response.

Immune system Both innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism's body that can be distinguished from foreign substances by the immune system.he ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence. In developed countries, obesity, alcoholism, and drug use are common causes of poor immune function.

Immune System Research Immune Tolerance. Tolerance is the prevention of an immune response against a particular antigen. For instance, the immune system is generally tolerant of self-antigens, so it does not usually attack the body's own cells, tissues, and organs. However, when tolerance is lost, disorders like autoimmune disease or food allergy may occur.

A susceptible or non-immune person is one who has little resistance against a particular organism and who, if exposed to this organism, is likely to contract disease.he term host is used to connote the living body upon which or in which a disease agent or parasite lives--the final recipient of an infectious agent. The susceptibility of a host to invasion by infectious agents is dependent upon a number of factors. a. Age.

Immune system Both innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism's body that can be distinguished from foreign substances by the immune system.[13] Conversely, non-self molecules are those recognized as foreign molecules.

The Immune System These mechanisms are divided into two groups: specific mechanisms and the nonspecific mechanisms. Specific mechanisms are part of the immune system and consist of the humoral immune response and the cellular immune response that produce antibodies and defense cells against specific antigens, respectively.

Whats the difference between specific and nonspecific responses in immunulogy? Report Abuse. a specific response is a response from the immune system to fight off a specific pathogen. Non specific responses from the immune system are response that are given out for any pathogen that enters the body.Non specific responses happen regardless of the pathogen that the immune system is fighting.on-Specific= Innate based. Neurophils, macrophages, - all using toll-like receptors or lps receptors, that engulf any pathogen, without caring what the pathogen is. It is not tailored to any specific pathogen and treats all equally.
