What are the body nonspecific defense? Natural immunity. For example: Your skin is a natural immunity. It is non-specific and is a barrier to the outside world. Your body has various non-specific defenses to pathogens such as bacteria and viruses. But overall the non-specific defense system is made up of skin, epithelial tissue, and mucous membranes which are always on and preventing pathogenic attacks so to speak.

- Adaptive Immunity in Prokaryotes. The ability of a multicellular organism to defend itself against invasion by pathogens (bacteria, fungi, viruses, etc.) depends on its ability to mount immune responses.

About Lymphocytes and Phagocytes...? The first part of the immune system that meets invaders such as bacteria is. a group of proteins called the complement system. These proteins flow freely in the blood and can quickly reach the site of an invasion where they can react directly with antigens-molecules that the body recognizes as foreign substances.nnate immunity also includes the external barriers of the body, like the skin and mucous. membranes (like those that line the nose, throat, and gastrointestinal tract), which are the. first line of defense in preventing diseases from entering the body.

Nonspecific Defense Whereas only vertebrates have specific immune responses, all animals have some type of nonspecific defense. Examples of nonspecific defenses include physical barriers, protein defenses, cellular defenses, inflammation, and fever.acrophages, neutrophils, and eosinophils are examples of phagocytes. In their attempt to defend the body, some phagocytes stay within a tissue and others travel freely throughout the body. However, all phagocytes are attracted to sites of tissue damage.

- 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.ll white blood cells (WBC) are known as leukocytes. Leukocytes are different from other cells of the body in that they are not tightly associated with a particular organ or tissue; thus, they function similar to independent, single-cell organisms.

Immune Response â Overview The immune system protects the body from invading disease-causing organisms, or pathogens. Pathogens and other non-self molecules are antigens  foreign molecules recognized by the immune system, stimulating an immune response.The majority of infections by pathogens occurs in mucous membranes of our body.athogens and other non-self molecules are antigens  foreign molecules recognized by the immune system, stimulating an immune response.

Host defense part I The body has a number of defenses against pathogens. These defenses fall into two types: 1  Nonspecific defenses are defenses that protect against any pathogen, regardless of the organism. 2  Usually, this pertains to the host, such as an intact skin and phagocytes that act against many potential pathogens. Be able to differentiate between non-specific and specific defenses. 2  Be able to give examples of nonspecific defenses, (both mechanical and chemical defenses). 3  Be familiar with the various kinds of blood cells and their roles.

Radiation Protection Chapter 6 Study Questions T/F- The skin is the body's initial barrier to any outside invasion by pathogens; however, once the skin has been penetrated, the body's primary defense mechanism against infection and disease consists of the hormones that chemically attack any foreign invaders or antigens.

Immune system How does the immune system protect us from disease? The immune system includes physical barriers, such as the skin and mucous membranes that prevent pathogens from entering the body, and cellular responses, such as circulating macrophages that respond to foreign invaders. Our acquired immune system mounts a specific antibody response when the body is exposed to a foreign invader, and our immune cells attack the invader.

- 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.his 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.

- The body's first line of defense against pathogens uses mostly physical and chemical barriers such as sweat, skin, tears, mucus, stomach acid, and so on.Our skin and other membranes which line the body passages are fairly effective in keeping most pathogens out of the body.he Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defense … s act the same way to all pathogens, in which they're called non-specific defense.

Glossary of HIV/AIDS-related Terms: The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: 1  Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

Introduction General Non-specific Defenses Against Infection. There are several simple physical and chemical barriers that constitute and important first line of defense. Our skin provides a highly effective barrier to infectious agents despite the fact that skin is colonized by an impressive array of microbial agents.

- 2-5. Complement is a system of plasma proteins that interacts with pathogens to mark them for destruction by phagocytes. In the early phases of an infection, the complement cascade can be activated on the surface of a pathogen through any one, or more, of the three pathways shown in Fig. 2.8.
