PATHOLOGY

Detailed explanation-1: -Pus is composed primarily of live and dead neutrophil polymorphs. The presence of pus generally reflects an acute inflammatory process and activation of the innate immune system.

Detailed explanation-2: -Neutrophils are a type of white blood cell that clear bacteria and fungi from the body. They are also called granulocytes or pus cells. Neutrophils are produced in bone marrow and released into the blood.

Detailed explanation-3: -At the site of infection they engulf and kill bacteria. Eventually, the neutrophils die, and these dead cells are then phagocytosed by macrophages, which break them down further. Pus, therefore, is the viscous material composed of these dead neutrophils.
