Question

Which one provides non-specific defence against pathogens?

• A. T-cells
• B. Phagocytes
• C. B-cells
• D. Stem cells

Answer 1

The correct option is B Phagocytes

Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. They are essential for fighting infections and for subsequent immunity. Phagocytes provide the second line of defence which is considered as a non-specific defence because it destroys invaders in a generalized way without targeting specific pathogens. Phagocytes are activated when the pathogen is able to cross the first line of defence.

So, the correct answer is 'Phagocytes'.
