Understanding how your immune system functions can help you appreciate and anticipate your healthy days and less-healthy days. Your immune system can be roughly broken into three categories: Innate immunity: This includes secretion of mucus and some types of immune cells. Inflammation: When your body is exposed to foreign substances, such as bacteria, or are injured, your immune system will stage an inflammatory response. Acquired immunity: We develop acquired immunity when exposed to bacteria, viruses, and other substances. Acquired immunity includes B and T lymphocytes, and antibodies that have developed in response to infection and vaccination . . .
