System and Hormones
TEST TOMORROW
•Essential Question(s):
1. Create a double-bubble
map comparing and
contrasting the nervous
system and the endocrine
system.
KEY CONCEPT
The endocrine system
provides one of the means by
which organ systems
communicate and it produces
hormones that affect growth,
development, and
homeostasis.

KEY CONCEPT
The endocrine system provides one of the means by
which organ systems communicate and it produces
hormones that affect growth, development, and
homeostasis.
29.6 The Endocrine System and Hormones
Connect
• If you hear a loud BANG, your brain tells your body that
you could be in danger
• You may need to run or defend yourself
• Your brain alerts your endocrine system to send out
chemicals that will speed up your heart rate, increase
blood flow to your muscles, and get you ready for action!
29.6 The Endocrine System and Hormones
The endocrine system makes chemical signals that control
growth, development, and digestion.
• It is a collection of physically
disconnected organs
• responds to environment
May control:
• Cell division
• Cell death
• Sexual development
• Body temperature
• Alertness
• Salt levels…
29.6 The Endocrine System and Hormones
• The chemical signals made by the endocrine system are
called hormones, which are chemical signals or
messengers that influence cell’s activities.
29.6 The Endocrine System and Hormones
• Glands, the organs of the
ES, produce hormones and
are found in many different
areas of the body
– secrete hormones into
the blood stream
- As a hormone moves
through the body, it comes
into contact with many
different cells
- But it can only interact
with a cell that has
specific membrane
receptors
target cell
hormone
bloodstream
receptor
not a target cell
29.6 The Endocrine System and Hormones
• Only cells with certain receptors
can receive the signals
• Works like a satellite system
• Sends signals in all directions,
but you need special receivers
to get the signals
29.6 The Endocrine System and Hormones
• Works more slowly than the nervous system.

29.6 The Endocrine System and Hormones
• There are many glands located throughout the body.
Hypothalamus: makes hormones that stimulate
other glands to release hormones
Pituitary: controls growth and water in blood
Thyroid: metabolism, energy levels, digestion
Thymus: helps white blood cells fight off infection
Adrenal Glands: breathe faster, increase blood
pressure- heart increases strength
Pancreas: Controls blood sugar by adding or
removing sugar from the blood
Ovaries and Testes: Cause sexual maturation,
influence sexual characteristics

The Endocrine System (3m)
29.6 The Endocrine System and Hormones
1) How does releasing hormones help glands to
communicate with one another?
• The glands are not connected. Releasing hormones
stimulate other glands to produce and release their
hormones.
29.6 The Endocrine System and Hormones
Hormonal imbalances can cause severe illness.
• Abnormal hormone levels affect homeostasis.
• Hormonal imbalances might be treated with surgery or
medicine.
29.6 The Endocrine System and Hormones
Robert Wadlow- (1918-1940)
•8 ft 11.1 in and 485 lbs
•Pituitary gland disorder- gave
him too much of the growth
hormone
•Used leg braces to walk, had
little feeling in his legs and feet
•Died at the age of 22 from an
infected ankle blister
Tallest man EVER recorded!
29.6 The Endocrine System and Hormones
Jon Brower Minnoch (19411983)
•Heaviest man ever recorded
•Peak weight 1,400
lbs
•Suffered from generalized edema
– his body retained massive
amounts of fluid. Over 900 lbs
was due to the fluid.
•Was hospitalized. Put on a strict
diet and dropped to 475 lbs
•Returned a yr later weighing 952
lbs
•They discontinued treatment
because his edema was incurable

NEED EXTRA CREDIT???
• Watch “Body Story: Teen Dreams”
• Write ½ page summary and turn in by Friday
• Focus on the glands of the Endocrine System
discussed
• https://www.youtube.com/watch?v=DGVPQF03tfI

EQ: Top P. 36
• Create a double-bubble map
comparing and contrasting the
nervous system and the endocrine
system.
• Must have at least two pictures
per system
