The immune system is the body's natural defense system that
helps fight infections. The immune system is made up of antibodies, white blood cells,
and other chemicals and proteins that attack and destroy substances such as bacteria
and viruses that they recognize as foreign and different from the body's normal healthy
The immune system is also responsible for allergic reactions and allergies,
which may occur when the immune system incorrectly identifies a substance (allergen),
such as pollen, mold, chemicals, plants, and medicines, as harmful.
the immune system also mistakenly attacks the body's own cells, which is known as
an autoimmune disease.
