D1 The Immune System Functions The immune system has two main function to recognize invading pathogens and then to trigger pathways that will destroy them. The humoral immune system relies on B lymphocytes to produce soluble antibodies that will bind the foreign antigens. The cellular immune system uses killer T lymphocytes that recognize and invading cells directl
• Functions The immune system has two main function to recognize invading pathogens and then to trigger pathways that will destroy them. The humoral immune system relies on β lymphocytes to produce soluble antibodies that will bind the foreign antigens. The cellular immune system uses killer T lymphocytes that recognize and invading cells directly. D1 The Immune System
Primary and secondary Immune responses The primary immune responses occurs on initial contract with a foreign and results in production of immunoglobulin M(gM) and then immunoglobulin G (IgG). If the same antigens encountered again, immuno logical memory leads to a secondary immune responses that produces a much more rapid and larger increase in specific IgG production
