Cool Body Defences Against Bacteria References. Skin, the largest body organ, provides both a physical and a chemical barrier against the outside world. The first lines of defence against infection stop the pathogens from entering your body.
Phagocytes that are white blood cells engulf pathogens and macrophages which are a longer living phagocytes help digest the bacteria and protect the body. Understanding how our body works helps us stay fit and fight against possible infections. As well as the immune system, the body has several other ways to defend itself against microbes, including:

They are a form of chemical defence against infection. Bacteria inside the human body. Th1 cells, but not th2 cells, promote effective host response.
The Immune System Uses White Blood.

No Wonder We Need So Many Defences Against These Tiny Invaders!

We Now Turn To Consider The Ways In Which The Body Seeks To Defend Itself Against Infection By These Organisms.
Immunity to viral infection is caused by a variety of specific and nonspecific mechanisms. They are found everywhere, including in air, water, and food. Bacteria, viruses, and parasites that overcome this barrier are faced.
