B cells and H cells are two important cells in the immune system that help fight infection (1point)
B cells are a type of white blood cell that produce antibodies, which are proteins that can recognize and bind to specific antigens (foreign substances) on pathogens such as bacteria, viruses, and parasites. When an antibody binds to an antigen, it marks the pathogen for destruction by other immune cells.
T cells, on the other hand, are white blood cells that can directly attack and kill infected cells or cancer cells. They also play a role in regulating the immune response by releasing cytokines that stimulate other immune cells.
Both B cells and T cells are essential for a strong and effective immune response to infection and disease.
