Contrast the first line of defense with the main line of defense?
In the immune system, the first line of defense are mechanical and physical barriers, such as the skin and the cornea of the eye. The main line of defense, meanwhile, are the innate immunity and acquired immunity of an organism.
What is the difference between innate immunity and adaptive immunity?
Innate is non-specific. It includes the first and second lines of defense. The first line of defense contains the skin, mucus membranes, and normal micro-biota. The second line contains the complement system, phagocytosis, fever, and inflammation.Adaptive is specific. It includes the third line of defense. The third line of defense contains B cells, which make antibodies, and T cells, which kill the target pathogen, and encourages phagocytosis.There is a huge difference between innate and adaptive immunity. Innate immunity is one that is triggered as soon an antigen gets into the body. As for the adaptive, its has to be specific and will allow be introduced once the antigen is recognized.
What immune system consists of the skin protective secretion the inflammatory response and phagocytes.?
The immune system consists of two parts: innate immunity and adaptive immunity. Innate immunity is the system of defense that every human is born with. It consists of the skin, protective secretions, the inflammatory response, andphagocytes. If microorganisms are able to penetrate the physical barriers (the skin and protective secretions), the body responds in a nonspecific way by increasing the blood flow to the area. This allows phagocytes to take action. Phagocytes are white blood cells that eliminate the chances of infection by attacking foreign substances in the body.
What are the components of the second line of innate defenses?
there are 3 main component of immunity which helps to maintain the innate immunity. these are- 1. anatomical barrier such as skin, mucosal membrane, conjuntiva 2. physiological barrier such as fever, Ph, oxygen tension etcf. 3. phagocytosis which is performed by W.B.C.
Do epithelial cells reproduce fast?
Skin cells reproduce faster than other types of cells
Resistance of the skin to invading organisms is?
innate
What defends you from disease?
Physical barriers like skin and mucus membrane protects body from invasion of microorganisms. If they happen to cross these barriers, then 'innate immunity' of body kills the bacteria. If they happen to be pathogenic bacteria, then white blood cells go there and engulf them. They are helped by 'humeral' immunity of body. Thensubsequently immunity comes into action by 2 weeks to defend further attack by the same organism.
What are the benefits of innate immunity?
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.
The body's most specific defense mechanism is?
Natural immunity, such as skin. For example, the skin is a physical barrier that keeps out pathogens (disease causing factors).
Are non- specific body defenses are innate while specific are adaptive?
Innate is a broad general response against any pathogen. It is very quick response but it is limited in how well it can defend your body. It is absolutely necessary to have a functioning innate immunity or your adaptive immunity will not be able to respond efficiently. Adaptive has a very specific response against a pathogen. On first exposure it may time several weeks to acquire the appropriate defenses, however, on secondary exposure it is a very quick response. It has long term memory so you are protected for a long time against that same pathogen.
A positive tuberculin skin test shows cellular immunity to Mycobacterium tuberculosis How could a person acquire this immunity?
having the actual disease
Is basophil an Innate or Adaptive Immune system?
No, the first line of the immune system is the intact skin, mucous membranes and their secretions, normal microbiota all are physical barriers.
