Description:At magnification of 1125X, this photomicrograph of a specimen consisting of mucus strands revealed the presence of a pus cell, or a white blood cell, also known as a leukocyte, which displayed what is called a “ring nucleus”.
Pus is formed in response to what the body deems an attack on its normal healthy state, usually in response to the invasion by a pathogenic entity such as a bacterium or fungus, or to the presence of a foreign body, as in the case of a splinter. The ensuing inflammatory process, which begins in response to these events, attracts these white blood cells that act as part of the body’s defense mechanism, which in turn directly attack the invaders, and clean up the debris associated with the inflammatory process through the processes of phagocytosis and pinocytosis.
