When any cells in your body are damaged, your immune system initiates an
inflammatory response. First, the injured cells release histamine which
increases the permeability of nearby blood vessels. Second, the vessels
swell, and immune system cells known as phagocytes pass through the
capillary walls. Finally, the phagocytes ingest any foreign matter that has
entered the body.
How does the immune system’s inflammatory response stop external
factors from damaging the body’s internal environment?
a) The inflammatory response destroys any bacteria or viruses entering
the body before they can infect cells.
b) Inflammation causes blood flow to the affected are to decrease,
thereby eliminating the possibility of invading organisms infecting the
blood cells.
c) Inflammation causes a great deal of pain, and heightening pain levels
make blood and tissue cells less susceptible to invasion by
microorganisms.
d) The inflammatory response causes the body’s temperature to cools by
several degrees, preventing microorganisms fro being able to multiply.

singing behavior?
a)
b)
c)
d)
It is determined by the environment
It is an instinctive behavior
It is learned by trial and error
