Explain the following in not more than 70 words.

Activation of adaptive immunity

Answer 1

Activation of Adaptive Immunity:

1. Adaptive immunity is activated when a specific antigen enters the body.
2. Antigen-presenting cells recognise, engulf and process the pathogen.
3. These cells present the antigen to T-helper lymphocytes, which activate specific B and T lymphocytes.
4. B lymphocytes differentiate into plasma cells that produce antibodies.
5. T lymphocytes help destroy infected cells.
6. Memory cells are formed, providing a faster and stronger immune response during future infections.
