What type of immunity may be gained by coming down with a disease?
Acquired immunity: When a person gets sick from a disease, their body produces antibodies to fight off the infection. After recovery, the body retains memory cells that recognize the specific pathogen if it reappears, providing immunity against future infections.
Type of resistance that is acquired as a result of developing a disease?
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.
What is the difference between acquired and passive immunity?
Acquired immunity is developed by the body after exposure to a pathogen or vaccine, leading to the production of antibodies. Passive immunity is temporary protection acquired through the transfer of pre-formed antibodies, such as from mother to child during pregnancy or through receiving injections of antibodies.
What type of immunity a person is born with called?
Acquired
What is the difference between natural immunity and acquired immunity?
Naturally acquired immunity occurs through contact with a disease causing agent, when the contact was not deliberate, whereas artificially acquired immunity develops only through deliberate actions such as vaccination. they are both immunitys
What is naturally acquired immunity?
Naturally acquired active immunity means that you have contracted the disease and your body has developed immune defenses against the disease. An example if when a person gets Chickenpox- the body has memory cells which functions to produce an immune response when it recognizes the same virus later on. The immunity for chicken pox is usually lifetime.
What are two ways in which active immunity can be acquired?
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
Why is AIDS considered a disease of the immunity system?
Acquired Immune Deficiency Syndrome - it weakens the bodies immune system, leaving the person incapable of fighting diseases.
Explain how vaccines help in combating diseases?
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's 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 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.
What type of immunity are antibodies given to a person?
Artificially acquired Active- vaccines (active or live viruses that are lifelong immunity) Artificially acquired Passive - gamma globulin injection that is temporary (used for overseas trips)
Distinguish between natural immunity and artificial immunity?
Natural immunity occurs through contact with a disease. There are two types of natural immunity. Actively acquired and passively acquired. Actively acquired - When the body has already experience an infection by that pathogen Passively acquired - Antibodies pass across placenta providing a newborn baby with immunity against disease. Antibodies are also present in breatsmilk. Artificial immunity develops through delibereate action such as vaccine. There are two types: Actively acquired and passively acquired Actively acquired - This is by vaccination at a suitable time in the person's life, not when they are infected. eg TB vaccine Passively acquired - The vaccine contains ready-made antibodies which provide immediate relief by destroying the antigens. This is given when the person has been infected with the antigen and has no preivous immunity eg tetanus
Which condition is acquired temporarily when a person receives antibodies from a outside source?
passive immunity
