Transcript The Endocrine system

Warm Up
 Put project on desk to be stapled &
collected
 Read “Endocrine System” article and
answer questions
The Endocrine
system
Glands and hormones
The Endocrine System
Function – controls
and maintains
various body
functions with the
help of glands that
release chemicals
called hormones
The Endocrine System is made of
Glands and Hormones
Gland –a group of cells that produce
hormones (the main structure of the
endocrine system )
Hormones – chemical “messengers” made in glands
that travel through the blood to specific parts of
the body.
Called chemical messenger because they are made
at one location but travel to another to function
• Different
hormones have
different jobs.
• The job depends
on the gland they
are made in
Glands
 There are 8 main glands in
the human body

Major Glands of the Endocrine system
 Pituitary
 Hypothalamus
 Pineal Gland
 Thyroid (AKA Parathyroid)
 Thymus  Adrenal Gland -
 Pancreas –
 Ovaries / Testes
Textbook Page 112B
For each gland of the endocrine system, you must know
1. Location
2. What hormones it makes and what those hormones do in
body
3. Other information dependent on gland
Major Glands of the Endocrine system
 Pituitary  Hypothalamus – Jose, Mason,
 Pineal Gland – Tarvarya, Drew
 Thyroid (AKA Parathyroid) – Eldin, Chris, Marvin, Flor
 Thymus - Alfonso, Dajah, Emely, Jennifer
 Adrenal Gland - Isaiah, Xavien, Shamod
 Pancreas – Ramon, Guadalupe, Deaundray
 Ovaries / Testes
Pituitary Gland
Location > base of the brain,
above roof of mouth
Hormone > control growth,
sexual development,
absorption of water into
blood by kidneys (how
much water the kidneys
take from the blood)
Other info > the director /
controller of the
endocrine system
Things that can go wrong…
 Giantism-
oversecretion of
somatotropin
before puberty
 Dwarfism-
undersecretion of
somatotropin.
Cause: tumor,
injury, infection,
genetics
 Diabetes insipidus-
decreased ADH
Hypothalamus
Location > attached to
pituitary glad (in brain)
Hormones > sleep and
hunger
Other info > connection
between nervous
system and endocrine
system
Pineal Gland
 Location > deep in brain
 Hormones> Controls sleep
body temperature,
reproduction and aging
 Other Info > size of pea,
sensitive to light
Thyroid
 Location > throat,
under Adam’s apple
 Hormone > growth,
metabolism and
regulation of calcium
in blood.
 Other info - Thyroid
gland must have
iodine to function
Thyroid Problems
 goiter- not enough iodine


hyperthyroidism
hypothyroidism
Thymus
 Location > in your chest
 Hormones > Controls and
creates White Blood Cells
 Other info > Slowly gets
smaller over time,
important to circulatory &
immune systems
Adrenal Glands
 Location > top of the
kidney
 Hormones > about 30
different ones, most
important =
Epinephrine/Adrenaline
 Other info = hormones
from here give you a quick
burst of energy and fight
allergies.
Pancreas
 Location > beneath
stomach, connected
to small intestine
 Hormone> insulin and
glucagon (regulate the
amount of glucose in
blood)
 Other info > important
in digestive system
too, diabetes if it
doesn't work right
Diabetes
 Cause- decreased secretion of insulin
 Symptoms
 Excessive thirst, excessive urination,
hyperglycemia, slow healing of skin
infections
 Affects 21 million in US: 7% of population
 Estimated 1/3 of people who have
diabetes don’t know it
 225,000 die each year
 132 billion/year- 10% of our health care
spending
 Insulin was the first hormone identified (late 1920's) which
won the doctor and medical student who discovered it the
Nobel Prize (Banting and Best)
 1982 - Human Insulin - First ever approved genetically
engineered human therapeutic by Genentech
Ovaries and Testes
 Location > lower abdomen
 Hormone > control sexual
development
 Ovaries = estrogen
 Testes = testosterone
 Other info >
Ovaries = female
Testes = male
Homework
 Write 1 paragraph (5 sentences) about what you learned
today about the Endocrine System
Warm Up – copy sentence and fill
in blank. Put HW on desk
1. Glands in the Endocrine system produce
_______________.
2. The gland that controls the amount of white
blood cells in the body is the __________
3. The _________ is the gland in both the endocrine
system and the digestive system.
1. Glands in the Endocrine system produce HORMONES.
2. The gland that controls the amount of white blood cells
in the body is the THYMUS
3. The PANCREAS is the gland in both the endocrine
system and the digestive system.

Ovaries / Testes
Foldable Inside (write on flap)
* Pituitary = growth, sexual
development, absorption of
water into blood by kidneys.
The master gland
*Hypothalamus = hunger. Controls
pituitary gland’s hormones
*Thymus = creates white blood
cells that fight infection.
Important in circulatory and
immune systems
*Pancreas = insulin and glucagon >
help with blood sugar levels. In
digestive and endocrine
*Pineal = sleep, body temperature,
reproduction and aging
*Thyroid = Growth, metabolism,
regulation of calcium
*Adrenal = Epinephrine (fight
allergies)
Adrenaline ( increase heart beat)
*Ovaries / Testes =
Control sexual development
Estrogen – ovaries (women)
Testosterone – testes (men)
