ANATOMY

Detailed explanation-1: -When the body detects an infection, it sends neutrophils, a type of white blood cell, to destroy the fungi or bacteria. During this process, some of the neutrophils and tissue surrounding the infected area will die. Pus is an accumulation of this dead material.

Detailed explanation-2: -Share on Pinterest Pus consists of macrophages and neutrophils, sent by the body’s immune system to combat infection. Pus is the result of the body’s natural immune system automatically responding to an infection, usually caused by bacteria or fungi.

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.

Detailed explanation-4: -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-5: -The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC).
