I WONDER - Are There Different Types Of Immunity?

The video tutorial explains the two basic types of immunity: natural and acquired. Natural immunity acts as a general defense against pathogens, with examples like skin, mucus, and earwax blocking antigens. Acquired immunity involves the body's cells remembering past antigens to mount a stronger response upon re-exposure.

• Innate and Adaptive

• Acquired and Artificial

• Natural and Acquired

• Natural and Artificial

Which of the following is an example of natural immunity?

• Antibody production

• Skin barrier

• Memory cells

What role does mucus play in natural immunity?

• It produces antibodies.

• It blocks antigens from entering the body.

• It remembers past infections.

• It enhances the immune response.

How does acquired immunity differ from natural immunity?

• It is present from birth.

• It is non-specific.

• It remembers past antigens.

• It involves physical barriers.

What happens when the body encounters a previously attacked antigen?

• The body becomes immune to all antigens.

• The body produces new antigens.

• The body attacks it more strongly.
