WHY PUS IS WHITE?

WHY PUS IS WHITE?

PROF WAQAR HUSSAIN

          

        The pus is the dead bodies of white blood cells- body soldiers who laid down their lives while fighting with the invading enemy (bacteria) trying to disrupt body.

          Scientifically, pus is a protein-rich thick fluid “liquor puris” usually white, whitish-yellow, greenish or yellow brown. Pus consists of a buildup of dead leukocytes (white blood cells) from the body's immune system in response to infection that accumulates at the site of inflammation. If this upsurge is very near the surface of the skin it is called a pustule or pimple (phora or phinsi in Urdu and gharr in Punjabi). An accumulation of pus in an enclosed tissue space is called an abscess. The ultimate composition of pus is dead white blood cells, dead skin cells and bacteria still fighting to enhance their number and got control of body. So, there is a point of caution in dealing with pus as it can cause infection in other healthier part of bodies or in other healthy person. So, a proper care is required to get rid of pus by using proper antiseptic liquid or gel.
