Cytotoxic T cells play a crucial role in the adaptive immune response by identifying and destroying infected or abnormal cells in the body. They recognize specific antigens on these target cells and release toxic substances to kill them, helping to eliminate the threat and prevent further infection.
Antibodies are proteins produced by the immune system that help identify and neutralize harmful pathogens like viruses and bacteria. They play a crucial role in the adaptive immune response by recognizing specific antigens on these pathogens and marking them for destruction by other immune cells. This targeted response helps the body fight off infections more effectively.
The adaptive immune response has memory, which means it can remember specific pathogens it has encountered before. This memory allows the immune system to recognize and respond more quickly and effectively to the same pathogen upon re-exposure. This helps the body to mount a faster and stronger immune response, leading to a quicker recovery from the infection.
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.
Looking for antigens is part of a specific immune response.
The classical pathway is part of the adaptive immune response and is triggered by specific antibodies binding to pathogens. The alternative pathway is part of the innate immune response and is activated by the presence of foreign substances on the surface of pathogens.

B cells play a role in producing antibodies, while T helper cells (Th cells) help activate and coordinate the immune response. Cytotoxic T cells (Tc cells) are responsible for directly killing infected cells. Both Th cells and Tc cells are types of T cells, with Th cells regulating the immune response and Tc cells directly attacking infected cells.

Looking for antigens is part of a specific immune response.
An antigen is actually foreign or toxic to the human body. It stimulates an adaptive immune response and binds to a antibody.
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.
