What does the immune system do to prevent viruses?
White Blood Cells
They circulate throughout the body in a coordinated system between organs and lymphatic vessels so that they can monitor the entire body consistently.
There are two types of white blood cells, Phagocytes which chew up invading organisms
The second type are Lymphocytes that allow the body to remember previous invaders and help to body kill them
When Viruses are detected, several different types of cells work together to kill these foreign predators. Lymphocytes are triggered start to produce antibodies, specialized proteins that detect the viruses.
Once produced, these antibodies continue to exist in a person's body, so that if the same antigen is presented to the immune system again, they can attack again.
Passive immunity is "borrowed" from another source and it lasts for a short time. For example, antibodies in a mother's breast milk provide a baby with temporary immunity to diseases the mother has been exposed to. This can help protect the baby against infection during the early years of childhood.
