IMMUNOLOGY

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: -Pus is a sign that a wound is infected but it is also a sign that your body is trying to fight the infection and heal the injury. Once an infection has started, your immune system begins trying to fight it off. It sends white blood cells to the area to destroy the bacteria.

Detailed explanation-3: -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. They control infection by travelling into body tissues to kill microorganisms, such as bacteria and fungi.
