Host Defense Mechanism Flashcards
It is a study of specific resistance to further infection by a particular microorganism to its product
Immunology
Lives on the body of the host or another organism
Parasite
The one who owns the body and the one harming the parasites and possibly causing death
Host
Live together which is the other is harming the other
Host parasite relationship
The resistance offered by the host to the harmful effect of pathogenic microbial infections
Immunity
Natural resistance with which a person is born
Innate immunity
Acquired immunity when a person meets antigens after birth
Specific immunity
Depends on antibody production against specific antigen by b cells
Humoral immunity
Directly kills foreign cells with the help of helper t cells and the cytotoxic cells
Cellular immunity
Help fight off infection and can provide protection against getting those diseases again
Antibodies
Substances that cause an immune response in the body in identifying substances and trying to eliminate them
Antigens
Is a state of resistance to an infectious agent
Immunity
It depends on the ability of the body to recognize and dispose of foreign microorganism and other naturally occurring organic substances including pollen dust and cells from other organisms
Immunity
Not specific to a certain group of microorganisms. These defenses mechanisms act against each invader of the body
Non-specific (innate)
What are the two types of immunity
Non-specific (inmate) and specific (acquired/adaptive)
Immunity that an organisms develops during a lifetime result of exposure to antigens such as microbestoxins or other foreign substances
Specific (acquired/adaptive)
The second line of defense involves the production of antibodies and the generation of specialized lymphocytes against specific antigens
Specific (acquired/adaptive)
Basic immunity which may be genetically passed on from one generation to another generation
Innate or non-specific immunity
An inborn result of the genetic constitution of the individuals
Innate or non-specific immunity
The first line of defense in innate immunity are the
Combination of physical and chemical barriers
Prevents the entry of microbes into the body
External system
Comes into play following injuries that breach the physical barriers
Internal system
What are the two systems in innate or non-specific immunity
Internal system and external system
Also helps remove bacteria and other infectious agents
Desquamation of skin epithelium
Provides an environment suitable for the survival of microbes
Presence of sebaceous glands
Washes infections off
Presence of sweat glands that secretes sweat
What dries microorganisms off
High salt content of sweat
The first barrier and the first mechanism of non-specific defense
The skin
Forms a physical barrier that is impermeable to most infectious agents acting as the first line of defense against invading organisms
The epithelial surface s
Movement due to peristalsis or cilia helps remove infectious agent
Respiratory tract and digestive tract
What are the five characteristics of components of natural resistance
The respiratory tract
the digestive tract
the mouth the eye
the urogenital tract
helps prevent infection of the mouth
Saliva
Contains antibacterial properties due to lysozyme
Saliva
The flushing action of ___ helps prevent infection of the eyes
Tears
This traps infectious agent
Mucus
