A common symptom of widespread inflammation in which elevated body temperature interferes with the growth and replication of microorganisms. This helps the body fight infection.
Lymphocytes that are responsible for antibody-mediated immunity. They produce specific anitibodies that bind to specific antigens.
Lymphocytes that are responsible for cell-mediated immunity. These attack body cells infected by invading pathogens and cells altered by mutation.
