The human body has three primary lines of defense to fight against foreign invaders, including viruses, bacteria, and fungi. The immune system's three lines of defense include
physical and chemical barriers, non-specific innate responses, and specific adaptive responses
.

The immune system includes three lines of defense against foreign invaders:
physical and chemical barriers, nonspecific resistance, and specific resistance
. The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity.

The first line of defence is your innate immune system. Level one of this system consists of
physical barriers like your skin and the mucosal lining in your respiratory tract
. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.
What is the second line of defense in your immune system?
The second line of defense is
nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals
: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).
Which line of defense is most important?
The Body's MOST IMPORTANT Nonspecific Defense is
the SKIN
. UNBROKEN Skin provides a continuous layer that protects almost the whole body. Very Few Pathogens can penetrate the layers of dead cells at the skin's surface.
