• How do hormones work in the
Endocrine system?
•
When your body temperature is higher
than 98.60 F, your thermostat in
hypothalamus turns on your internal
air condition, thus causing your blood
vessels to dilate or open up in order to
release heat. Also, your sweat glands
get turned on causing you to sweat.
•
Lastly, your body temperature drops
back down to normal or Homeostasis.

When your body temperature is higher
than 98.60 F, your thermostat in your
hypothalamus turns on your internal
air conditioner, thus causing your
blood vessels to dilate or open up in
order to release heat. Also, your sweat
glands get turned on causing you to
sweat.

Now, when your body temperature is lower
than 98.60 F, your thermostat in the
hypothalamus turns on your internal heater,
thus causing your blood vessels to constrict
or close in order to keep heat in. Also, your
skeletal muscles get turned on; causing you
to shiver.
“Global warming or not, its still freezing here.”

Lastly, your body temperature rises back to
normal or Homeostasis.

•After we eat, our body’s glucose(sugar) level
rises. This stimulation causes the pancreas to
release insulin-a hormone, into the blood stream.
After this, the liver and other cells will take in the
sugar, allowing the sugar level to drop to a
certain point and end back at Homeostasis.
•If we do not eat for a long time, our glucose
level will drop. The drop (the stimulus) in sugar
will cause our pancreas to release Glucagon into
the liver which will then breakdown into glucose,
to be released into the blood. This allows the
sugar level to rise and once again reach
homeostasis.

•When women are going through
child labor, the babies head pushes
on the cervix. This stimulation allows
the pituitary gland to release the
hormone Oxytocin. After oxytocin is
secreted (released), it is then carried
in the bloodstream to the uterus.
Once at it’s destination, oxytocin
stimulates the uterus to contract.
•This process will continue until the
baby has come out.
•Oxytocin hormone is also involved in
producing milk in the mammary
glands for breastfeeding.

•Hormones are also involved in how much
we grow. This hormone is known as the
growth hormone or simply GH.
•This Hormone can have various effects
on people. For example, if the
hypothalamus produces too much GH
then the end result could lead to
Gigantism.
•If too little GH is produced, then the end
result could lead to Dwarfism.
