The correct Answer is:
A
Second line of defense is nonspecific, mounting similar response against all pathogens irrespective of the identity. It include :
* Phagocytes : Include macrophage and white blood cells specifically neutrophils and monocytes.
* Inflammatory Reactions : Tissue damage caused by wound or invading pathogenic organisms induce a complex sequences of events collectively known as inflammation.
* Fever : Pyrogens released from damaged tissue and cells involved in inflammation induce a rise in temperature.
* Antimicrobial infection.
