ENDOCRINE SYSTEM
By: Mr. Mott
WHAT DOES THE ENDOCRINE
SYSTEM DO?
• The endocrine system controls your body
functions. It produces hormones the
travel throughout your body. The
hormones help maintain your tissues and
organs.
• Aids with reproduction, responses to
stress and injury, growth and sexual
development, body energy levels, internal
balance of body systems, bone and
muscular strength.
PARTS OF THE ENDORINE SYSTEM
•
•
•
•
•
•
Hypothalamus
Pituitary Gland
Thyroid Gland
Parathyroid Glands
Adrenal Glands
Pancreas
HYPOTHALAMUS
• Located in the lower central part of the brain.
• It regulates metabolism and body temperature.
• It makes you feel hunger and thirst.
PITUITARY GLAND
• Located at the base of the brain, beneath the
hypothalamus. About the size of pea.
• Very important part of the endocrine system. It
produces hormones that control many functions of other
endocrine glands.
THYROID GLAND
• Located in the lower front part
of the neck.
• Produces hormones that regulate
the body’s metabolism.
• It also assists in bone growth
and development of the brain and
nervous system in children.
• Lastly, thyroid hormones help
maintain normal blood pressure,
heart rate, digestion, muscle
tone, and reproductive functions.
PARATHYROID GLANDS
•
•
Two pairs of small glands that are embedded in the surface of the
thyroid glans. One pair on each side.
The release a hormone that helps regulate calcium levels in the blood
and bone metabolism.
ADRENAL GLANDS
•
•
•
Triangular-shaped glands located on top of each kidney.
Assists in regulating the body’s metabolism, balancing the salt and
water in the body, immune system, and sexual function.
In addition, the adrenal glands help the body cope with physical and
emotional stress by increasing heart rate and blood pressure.
PANCREAS
• It is an elongated organ located
toward the back of the
abdomen behind the stomach.
• It secrets digestive enzymes to
help break down food.
• Also, it secretes insulin (to help
regulate the level of glucose,
sugar, in the blood.
VOCABULARY
• Adrenaline-stress hormone produced
within the adrenal gland that quickens
the heart beat.
• Gland-a group of cells that secrete a
substance for us in the body.
• Hormones-chemicals that are produced
by endocrine glands.
SYSTEM FAILURE
• The endocrine system may produce too much or too little growth
hormone (very tall or very short).
• Diabetes-When the pancreas has issues with insulin (2 types).
• Hyperthyroidism-when levels of thyroid hormones in the blood
are excessively high
• Hypothyroidism-when levels of thyroid in the blood are
abnormally low.
KEEPING THE ENDOCRINE SYSTEM HEALTHY
• Eating right, exercising, getting plenty
of sleep, and reducing your stress level
with help keep your hormones and
endocrine system balanced.
FACTS
• Alcohol has widespread effects on the
endocrine system.
• Plants produce hormones without having
an endocrine system.
• There are over 30 hormones in the
human body.
