immune system -protects our bodies from foreign pathogens, or
infectious agents
-comprised of the lymph nodes, thymus, bone
marrow, and spleen
-all immune cells are born in the bone marrow
but can mature in different locations across the
body
first line of defense -physical barriers, such as the skin, which prevent
most pathogens from accessing our bodies
-when these barriers are breached, immune cells
from the innate and adaptive arms target
pathogens for destruction
-skin has a acidic pH b/t 3 and 5, which
discourages replication of most pathogens
-skin is inhabited by flora
pathogens foreign infectious agent
, innate arm -quick to respond, but not specific to individual
pathogens nor does it form memory cells
adaptive arm -slower to activate, but it specifically targets a
pathogen and forms memory cells
adaptive immunity (slow response) -B cell releases antibodies
-T cell forms a CD4+ T cell and a CD8+ T cell
-quick to respond but unable to form memory
-this system consists of granulocytes, monocytes,
and natural killer cells
-slower to respond b/c it must first be activated
by antigen presentation by cells of the innate
immunity system
-once activated, it will specifically target
pathogens and host cells displaying the
presented antigen
-includes both T and B cells
-normally self tolerant
