What process involves the formation of pus?

The process of pus formation is known as suppuration. This occurs when certain types of inflammation, particularly acute inflammation, lead to the accumulation of neutrophils, dead cells, and bacteria, resulting in the creation of pus. Suppuration typically arises from infections, where the immune system sends white blood cells to the site of infection to fight off pathogens. The dead cells from the immune response, combined with bacteria and tissue debris, culminate in the thick, yellowish fluid known as pus.

This process is vital for healing since it signifies the body’s attempt to contain and eliminate harmful invaders. The presence of pus often indicates an ongoing inflammatory response and may require medical attention, especially if it leads to the formation of abscesses. Understanding suppuration is crucial in pathology as it explains how the body responds to infections and injuries.
