immunity is produced by an individual after natural exposure to an antigen or after
immunization
Active
immunity produces immunoglobulins that bind to antigens and neutralize their effects
Humoral
stimulates the proliferation of T cells and B cells during inflammation
Interleukins
Catecholamines decrease which of the following immune system cells during chronic
stress?
Natural Killer cells
interfere with insulin signaling leading to insulin resistance in stress, obesity, and Type 2

what type of immunity is produced when an immunoglobulin crosses the placenta?
Passive acquired
the normal microbiome
The body's surfaces are colonized with a variety of microorganisms, Surfaces, such as
skin and mucous membranes of eyes, upper and lower GI tracts, urethra and vagina are
colonized by a combination of bacteria and fungi that are unique to a particular location
and individual.
If immunocompromised the microbiome can lead to
opportunistic infections or loss of integrity of the body surface areas.
