  hormones into the blood stream

What it produces

• Growth hormone- stimulates the growth of bone and
  other body tissues.
• Prolactin- Activates milk production in women who
  are breastfeeding.
• Thyrotropin- Stimulates the thyroid gland to
  produce thyroid hormones.
• Corticotrophin- Stimulates the adrenal gland to
  produce certain hormones.

Hormones and what they do

• They are chemical messengers that travel through
  the body
• It helps with growth metabolism and fertility
• Before birth they help develop the brain and
  reproductive system
• Hormones are the ones that decide how your body

Negative feed back loop

• if there is a data that produces a result in the
  opposite directions its a negative.
• The affects that they have depends on the system.
  
• They can have different behavior
• They have exponential growth or decline
• There is maintenance of equilibrium.

Blood glucose

• The levels of glucose have to stay the same
• The body regulates blood sugar levels using two
  mechanisms hunger and insulin
• When the blood glucose falls it cause people to
  be hungry
• If we dont eat then the blood glucose falls to
  low and it cause us to have hypoglycemia
• When our blood-glucose levels rise, the brain
  tells our pancreas to release insulin
• Without insulin the amount of sugar in our blood
  can become toxic
