1. Endocrine (Hormonal) System
Maisie Sattler & Robyn Siebers

2. Vocabulary
A Hormone - chemical released by a gland or cell that affects other parts of the body.
Glands - are organs that release substances such as hormones.
Glucose - sugar in human metabolism.

3. Explanation
The endocrine system works by the 10 main glands producing different hormones to help the body function properly.
It is important because the endocrine system controls the body, but through chemical messengers; with the glands releasing hormones into the bloodstream to get other organs/tissues.

4. Glands That Make Up the E.S.

5. Pituitary Gland: The master gland
Pituitary Gland: The master gland. Produces prolactin, Growth hormone (GH), Adrenocorticotropin (ACTH), Thyroid-stimulating hormone (TSH), Luteinizing hormone (LH), and the Follicle-stimulating hormone (FSH).
Thymus: gland needed in early life for normal immune function.
Hypothalamus: Produces growth hormone-releasing hormone (GHRH), thyrotropin-releasing hormone (TRH), and the corticotropin-releasing hormone (CRH).
Pineal Gland: Produces melatonin. Helps us sleep.
Testes: Produces testosterone & bring out physical changes.
Ovaries: Produces estrogen and progesterone.
Thyroid: controls your metabolism.
Parathyroid: makes hormones that helps control calcium levels in the body.
Adrenal Glands: Outer gland - adrenal cortex - helps control blood sugar
Inner gland: adrenal medulla - produces adrenaline
Pancreas: Helps the body maintain a healthy blood sugar by producing insulin.

6. Fun Facts
Even the slightest hiccup with the function of one or more glands can throw off the balance of hormones in your body, which can lead to an endocrine disorder.
The body produces 30 different hormones.

7. Teen Diseases Stress - Chemicals in body going insane
- Starts to feel familiar
Hypothyroidism - when thyroid is not active
Drugs & alcohol
can impair the
production of
hormones.

8. Disease & Prevention
Diabetes - when blood glucose levels are too high & the body does not produce insulin.
Exercise, weight control and sticking to a meal plan can control and prevent diabetes and keep the E.S. healthy.

9. Survival Without If we didn’t have an endocrine system:
We wouldn’t be able to grow
We wouldn’t be able to survive very long

10. Interactions Hypothalamus
- links the endocrine system and nervous system together so the body knows what hormones to release at a specific time.
- controls human behavior
Works with the skeletal system - controls bone growth
E.S. aids the immune system by helping the body build a resistance to disease
