3. Immunosuppressant

4. Immuno vaccine

Q. What happens if lymphatic system is absent in our body?

Q. Assertion :The thymus gland is quite large in size at the time of birth but shrinks in size with age. Reason: Immune system produces most of its T cells during childhood and requires very few new T cells after puberty.
