Innate immunity: Also known as natural or native
immunity, includes natural barriers (physical,
mechanical, and biochemical) and inflammation.
Innate barriers form the first line of defense at the
body's surfaces and are in place at birth to prevent
damage by substances in the environment and thwart
infection by pathogenic microorganisms.
Identify innate immunity
versus adaptive immunity. Adaptive immunity: The third line of defense (also
known as acquired or specific immunity), is included in
a relatively slower and more specific process and
targets particular invading microorganisms for the
purpose of eradicating them. Adaptive immunity also
involves "memory," which results in a more rapid
response during future exposure to the same
microorganism.
, Composition: These barriers are composed of tightly
associated epithelial cells of the skin and of the linings
of the gastrointestinal, genitourinary, and respiratory
tracts.
Purpose: Offer considerable protection from damage
and infection.

tract by urine. Epithelial cells of the upper respiratory
tract also produce mucus and have hair-like cilia that
trap and move pathogens upward to be expelled by
coughing or sneezing. (Biochemical) Additionally, the
low temperature, such as on the skin, and low pH,
