Immunity
Immunity is the power of the body to protect itself from pathogens and other agents. Many microbes and viruses can cause disease, known as pathogens. When these Pathogens enter in our body, Immunity of the body protects us from these Pathogens. Everyday our body comes in contact with several pathogens, but only a few results into diseases. The reason is, our body can release antibodies against these pathogens and protects the body against diseases. This defense mechanism is called immunity. If a person has low Immunity Power then Pathogens affect the whole body.
Types of Immunity:There are two major types of immunity:
1. Innate Immunity or Natural or Non-specific Immunity
This type of immunity is inborn. This is also called natural immunity. This is activated immediately when the pathogen attacks. Innate immunity includes certain barriers that keep foreign particles out of the body. It is a long-term immunity in which our body produces antibodies on its own.
2. Acquired Immunity or Artificial or Adaptive Immunity
This type of immunity protects the body from pathogens develops as we go through life. As we are exposed to diseases or get vaccinated, we build a lot of antibodies to different pathogens. This type of immunity is acquired by the body in response to a specific germ and learns to fight that antigen. It remembers and can fight in the future.
• Active Immunity: When the body proactively prepares an antibody against a specific antigen
• Passive Immunity: In this, the body does not make any antibody. The antibody is specially inoculated in the body from outside. For example, through vaccination.
