Acquired Immunity
Acquired immunity is the type of immunity that is acquired after birth. It is also known as adaptive immunity, as it involves the body's specific response to a particular pathogen.
- Types of Acquired Immunity:
- Acquired immunity can be further classified into two types: active immunity and passive immunity.
- Active immunity is developed when the immune system responds to a pathogen by producing antibodies or activating immune cells. This type of immunity provides long-lasting protection against future infections.
- Passive immunity, on the other hand, is acquired when antibodies are transferred from one individual to another. This type of immunity provides immediate but temporary protection.
- Development of Acquired Immunity:
- Acquired immunity is developed through exposure to antigens, either from natural infection or vaccination. The immune system recognizes these antigens and produces a specific response to eliminate the pathogen.
- Components of Acquired Immunity:
- Acquired immunity involves the activation of T cells and B cells, which are specialized immune cells that work together to target and eliminate pathogens. Memory cells are also formed during the immune response, providing long-term protection against reinfection.
Overall, acquired immunity plays a crucial role in protecting the body from a wide range of pathogens and is essential for maintaining overall health and well-being.
