WALT KNOW THE
HUMAN ENDOCRINE SYSTEM
Endocrine - ?
Hormone – what is it?
Exocrine or Endocrine
• Exocrine – release chemical products
(enzymes) into ducts
– Examples : Sweat, tears, digestive juices
• Endocrine – directly to bloodstream; NO
DUCTS
– Example : Hormones
Endocrine System
• Hormones – chemical products that travel in
the blood stream and causes changes in the
body in order to maintain homeostasis
• Glands – release hormones to bloodstream
directly.
• Target cells – have specific receptors for
specific hormones

Hypothalamus
• Part of brain and attached to pituitary
• Controls pituitary secretions
Pituitary Gland
• Master gland
– Controls the other
endocrine glands
• Growth Hormone (GH)
– Too much – gigantism
– Too little – dwarfism
• Antidiuretic (ADH)
– Stimulates kidneys to
keep water
WALT know the glands, hormones produced and their functions.
Task :
Watch the video.

1. Make a list of the names of the endocrine glands in the human body.
2. Name the hormone produced in each gland.
3. State the function of each hormone.

Endocrine Glands
Section 39-1
Hypothalamus
The hypothalamus makes
hormones that control the
pituitary gland. In addition, it
makes hormones that are stored
in the pituitary gland.
Pituitary gland
The pituitary gland produces
hormones that regulate many of the
other endocrine glands.
Parathyroid glands
These four glands release
parathyroid hormone, which
regulate the level of calcium
in the blood.
Thymus
During childhood, the thymus
releases thymosin, which
stimulates Tcell development.
Adrenal glands
The adrenal glands release
epinephrine and nonepinephrine,
which help the body deal with stress.
Pineal gland
The pineal gland releases melatonin, which
is involved in rhythmic activities, such as
daily sleep-wake cycles.
Thyroid
The thyroid produces thyroxine, which
regulates metabolism.
Pancreas
The pancreas produces insulin and glucagon, which
regulate the level of glucose in the blood.
Ovary
The ovaries produce estrogen and progesterone.
Estrogen is required for the development of secondary
sex characteristics and for the development of eggs.
Progesterone prepares the uterus for a fertilized egg.
Testis
The testes produce testosterone,
which is responsible for sperm
production and the development of
male secondary sex characteristics
Project Term 2 – Hormone Game
Aim – To create a game based on hormones.
Work in pairs, involves 4 phases :
Phase 1 – Planning (1wk)
Phase 2 – Creating (1wk)
Phase 3 – Presenting (1wk)
Phase 4 – Testing by G8 (1wk)
Each stage will be graded.
Project Term 2 – Hormone Game
Planning Phase
At the end of today‘s lessons, your team needs to hand in an information sheet.
It should include :
Name of hormone/s.
Name of gland that produces it.
What kind of hormone is it? Is it water soluble or lipid soluble?
How does it function?
Why we chose this hormone?
Good Luck.
Each stage will be graded.
Project Term 2
Creating phase
Computer games - Scratch

Quiz – on paper/computer
Who wants to be a millionaire?
The game should have these criterias :
- easy to understand instructions
- informative
- enjoyable
- not time consuming
End product – tidy, neat and attractive
Note : You have two weeks of `Creating
phase´.
Week 1 – brain storm ideas, rules etc.
Week 2 – the final product ready for
presenting and testing.
