Homeostasis Test Questions and Answers Rated A
homeostasis - -maintaining a constant
internal environment
vasoconstriction - -decreasing the diameter
of blood vessels to reduces blood flow
negative feedback - -movement away from
an ideal state triggers a mechanism to counteract
further change and returns the state to normal; sweat glands - -glands found on almost all
a change in a variable triggers mechanisms that body surfaces that help regulate body
reverse that change temperature by secreting sweat
equilibrium - -state of balance interstitial fluid - -liquid found between the
cells of the body that provides much of the
internal environment
fluctuation - -frequent and irregular change
regulate - -to control or direct by some
nervous system - -fast-acting network of particular method
nerve cells that transmit impulses between parts
of the body and brain in response to internal and
external changes thermostat - -a device used to control the
temperature
thermoregulation - -control of body
temperature stimulus - -a change in environment that
causes an organism to react
metabollic - -refers to all the chemical
reactions in living organisms that are necessary response - -an action or change in
to maintain life behavior that occurs as a result of a stimulus
metabolism - -all the chemical reactions in set point - -the point at which an
living organisms that are necessary to maintain individual's "normal" level is set for a variable
life
receptor - -a sensor that responds to a
endotherm - -organisms that use heat change in the environment
energy generated by metabolism and muscle
contraction to carefully control their internal body
temperature fluid homeostasis - -maintaining fluid (ie
water) levels in the body at a near constant level
vasodilation - -widening of blood vessels to
increase blood flow
