Feb 19, 2019 Immune system, the complex group of defense responses found in humans and other advanced vertebrates that helps repel diseasecausing organisms (pathogens). Immunity from disease is actually conferred by two cooperative defense systems, called nonspecific, innate immunity and specific, acquired immunity. Nonspecific protective mechanisms repel all microorganisms equally, while the specificThe specific defense system, more commonly the immune system, is the second type of defense system within the body. It's purpose is to comprise a specific defense measure against a pathogen. specific body defense system

08 Nonspecific and Specific Defenses. In this autoimmune disease the body make antiDNA antibodies that cause facial rash, fever, and joint pain. The central nervous system, heart, and kidneys can also be attacked and the results can be fatal.

How can the answer be improved? Specific Defence System (Immune System) This defence strategy uses very precise unique defensive proteins against a particular pathogen. The defence proteins are called antibodies, if the target is a pathogen, An antitoxin if the target is a poisonous chemical. specific body defense system Your internal defense systems kick in when the external defenses fail and something bad finds its way into your body. This could be a virus or bacteria, for example. This could be a virus or

An Overview: Nonspecific vs. Specific Defense Mechanisms. Strengthen immune response. Body Defenses: An Overview Specific Defenses: The Immune System Destroys foreign cells that cause disease Recognize self from nonself Inactivate toxins and other foreign Results in damage to various body tissues 2. specific body defense system Most viral infections are limited by nonspecific defenses, which (1) restrict initial virus multiplication to manageable levels, (2) initiate recovery from established infections that is then completed by a combination of these early nonspecific and subsequent antigenspecific immune defenses, and (3) enable the host to cope with the peak numbers of virus that, if presented as the infecting Nonspecific Defense. With nonspecific defenses, the protection is always the same, no matter what the invader may be. 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. Specific Defenses Against Infection. Defending Your Body. To defend against invadersbacteria, viruses, and other pathogensour bodies have two levels of defense. Nonspecific defense mechanisms; Specific defense mechanisms (a. k. a. the immune system) Specific Defense Mechanisms: The Ch 12 Specific Body Defenses. Pathogen and resulting antibodies cause release of histaminewhich causes small blood vessels to become dilated and leaky. Symptoms include: Runny nose, water eyes, itching, reddened skin (hives), bronchial constriction (asthma), and antihistamine drugs can
