Homeostasis- themaintenance of a
constant internal environment
- Body Temperature
- Temperature at
which enzymes
work best
- 37 C
- Too hot
- Sweat glands in the skin
release more sweat, which
evaporates, removing heat
energy from the skin
- Blood vessels leading to the
skin capillaries become
wider (dilate) allowing
more blood to flow through
the skin, and more heat to
be lost
- Too cold
- Muscles contract rapidly
(shivering), which needs
energy for respiration, some
of which releases heat
- Blood vessels leading to skin
capillaries narrow, letting
less blood flow to the skin
and conserving body heat
- Blood Sugar Level
- Provide cells with a
constant source of
glucose for respiration
- It is controlled by the release
and storage of glucose,
which is in turn controlled by
insulin.
- Water Content
- Controlled to protect
the cells to prevent too
much water entering or
leaving them
- Water is lost through the
lungs via breathing, the sking
by sweating and the body
through urine produced int
the kidneys
