An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
Acquired Immune System or Adaptive immune System
The adaptive immune system is activated if the innate immune system is unable to control the infection.
Toll-like receptors are part of the innate immune system.
T helper cells
The adaptive immune system was developed in higher vertebrates to combat pathogens and antigens. These can include viruses, bacteria, and anything else that can cause the immune system to launch an immune response.
When we say the adaptive immune response has "memory," it means that the immune system can remember specific pathogens it has encountered before. This allows the immune system to respond more quickly and effectively if the same pathogen enters the body again in the future.

Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.
it is a defense system of our body it fights off infections and sickness
