A strong immune system helps to keep a person healthy. Can specific foods boost the immune system?
The immune system consists of organs, cells, tissues, and proteins. Together, these carry out bodily processes that fight off pathogens, which are the viruses, bacteria, and foreign bodies that cause infection or disease.
When the immune system comes into contact with a pathogen, it triggers an immune response. The immune system releases antibodies, which attach to antigens on the pathogens and kill them.
