antibodies
Antigens are substances that incite your immune system to respond by producing antibodies. They include both foreign substances, such as pollen, and substances made by the body. Ones made by the body are non harmful.
Phagocytes, such as neutrophils and macrophages, are leukocytes that respond to nonspecific foreign invaders. They engulf and destroy pathogens through phagocytosis, helping to protect the body from infections.
The lymphatic system uses lymph nodes to filter and remove foreign material, such as pathogens, dead cells, and toxins from the body. Lymph nodes act as checkpoints where immune cells can detect and respond to harmful substances present in the lymph fluid.
The immune system's ability to recognize and resist specific foreign substances is determined by the unique set of proteins on the surface of cells called major histocompatibility complex (MHC) molecules. MHC molecules present antigens to immune cells, which stimulate the immune response. The immune system can only respond to antigens that are recognized by MHC molecules.
B lymphocytes, or B cells would produce antibodies.
