Question:what is the difference between passive and active immunity?
describe, with examples, how the body acquires artificial immunity through the antibody mediated (humoral) response
Answers:Passive immunity- you are given the antibodies that were produced elsewhere (eg, by a rabbit or horse).
Active immunity- you are given the antigen, and your body responds by producing the antibodies.
Artificial immunity (which can be interpreted as passive immunity) can be gained by the fetus as the maternal antibodies cross the placenta, or by the administration of antivenin.
Answers:Artificially acquired passive immunity refers to antibodies we receive from outside sources.
Artificially acquired active immunity refers to injecting ourselves with a safe form of antigens so that our own bodies make the required antibodies in response to the artificially injected antigens.
Question:what does passive immunity and active immunity mean?
Answers:Passive immunity is the transfer of active humoral immunity in the form of readymade antibodies, from one individual to another. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and can also be induced artificially, when high levels of human (or horse) antibodies specific for a pathogen or toxin are transferred to non-immune individuals. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases.
Active immunity: The production of antibodies against a specific agent by the immune system. Active immunity can be acquired in two ways:
by contracting an infectious disease -- such as, for example, chickenpox; or
by receiving a vaccination usually pe-- such as, for example, against polio.
Question:Before Frank took the cold pill, what kind of immunity was his body using to protect himself? Explain.
I know it's active immunity because that is when immunity forms against antigens, but I can't explain it in hw-teacher reads-form.
After Frank takes the cold pill, what kind of immunity was protecting himself? Explain.
Once again, I know the answer- passive immunity, but I again can't explain it in a form for the teacher to check.
Can you state it in a way which makes it sound mature, understandable,& legit, thanks.
Answers:before took pill = natural active immunity
after took pill = artificial active immunity
natural mean it from human body.
artificial mean it had been other than human body (lab etc), it also obtain from vaccination. this process is called immunization.
passive mean the individual is given the abtibodies required to destroy the pathogen.
active mean the body cell of an individual produce the antibody required to destroy the pathogen.
p/s: read and try to understand it slowly! it bit confusing ;)
Passive Immunity to Infectious Disease 1955 :Immunity to a disease is achieved through the presence of antibodies to that disease in a persons system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. For example, measles antibody will protect a person who is exposed to measles disease, but will have no effect if he or she is exposed to mumps. There are two types of immunity: active and passive. Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity). Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it. Active immunity is long-lasting, and sometimes life-long. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. However, passive immunity lasts only for a few weeks or months. Only active immunity is long-lasting.
