THE ENDOCRINE SYSTEM
- has two primary
- HORMONES
- released by
- GLANDS
- PITUITARY
GLAND

- THYROID
GLAND
- located
- front of neck, in
front of trachea

- contains
- four parathyroid
glands within
- produce
- parathyroid hormone
- which
- increase calcium levels in blood
and lower phosphate levels
- increase calcium levels in blood
and lower phosphate levels
- which
- parathyroid hormone
- produce
- four parathyroid
glands within
- produces
- thyroxin and
triiofothyronine
- which
- increase metabolism
and limit growth
- require iodine
present in thyroid
for production

- hormone producing
cells of pancreas are located in
- islets of Langerhans
- produce
- insulin
- produced by
- beta cells
- beta cells
- released when
- blood sugar rises
- blood sugar rises
- causes
- cells of muscles, liver
and organs to become
permeable to glucose
- liver to convert
glucose to glycogen
- which
- primary storage
of glucose
- lowers blood sugar

- made from
- cholesterol
- examples are
- sex hormones
and cortisol
- which
