The natural defense of the body is called ________.

Answer 1

Natural defense:

1. Also known as innate immunity or the first line of defense, this is the defense system of the body that a person is born with.
2. It includes the physical barriers (skin) and chemical barriers (mucous membranes, tears, earwax, mucus, and stomach acid).
3. They help to eliminate any substance that the body identifies as foreign or disease-causing.

Thus, the natural defense of the body is called innate immunity.
