Anatomy & Physiology Immune #3
A client has a history of chickenpox but there is no laboratory verification. Which type of immunity does this client have based on this data?
- Active immunity
Active immunity occurs when an individual produces antibodies against a pathogen and it is verified by laboratory testing. This type of immunity can be obtained as the result of getting a particular infection, or by being given an immunization against the particular infection.
- Passive immunity
Passive immunity occurs when a person gets antibodies with an immunoglobulin of antibodies. In addition, passive immunity is transferred from a mother to a fetus in utero; it is a short lived, or temporary, form of immunity.
- Natural immunity
Natural (i.e., innate) immunity does not require previous sensitization to an antigen. The skin is a structure that provides the human body with natural immunity.
- Artificial immunity
Artificial immunity is defined as immunity that is not acquired in a natural way. Immunization is a form of artificial immunity.
Immunity is defined as the ability of an organism to resist particular infections or toxins via specific antibodies or white blood cells that are sensitized.
There are four basic types of immunity within the human body. These types of immunity include active immunity, artificial immunity, natural immunity, and passive immunity. Natural immunity is defined as immunity that is acquired in a natural way, including a history of chickenpox.
Test Taking Tip
