1. The Endocrine System
Controls many body functions
exercises control by releasing special chemical substances into the blood called hormones
Hormones affect other endocrine glands or body systems
Releases hormones directly into the blood, which in turn transports the hormones to target tissues in the body.

2. The Endocrine System
Consists of several glands located in various parts of the body.
Pituitary gland: a small gland located on a stalk hanging from the base of the brain - AKA
“The Master Gland”
Primary function is to control other glands.
Produces many hormones.
Secretion is controlled by the hypothalamus in the base of the brain.

3. The Endocrine System The Hypothalamus:
Helps the body maintain homeostasis or internal balance by regulating things such as:
Body temperature
Blood pressure
Digestion
Breathing

4. When released, increases the metabolic rate (digestion).
The Endocrine System
The thyroid hormones:
When released, increases the metabolic rate (digestion).
The Thyroid Gland
lies in the anterior neck just below the larynyx.
Two lobes, located on either side of the trachea, connected by a narrow band of tissue.

5. Hypothyroidism can cause: Facial swelling weakness cold intolerance
The Endocrine System
Hypothyroidism can cause:
Facial swelling
weakness
cold intolerance
fatigue
oily skin and hair
Inadequate or low levels of thyroid hormones = Hypothyroidism

6. The Endocrine System Hyperthyroidism can cause:
bulging of the eyeballs
Thinning hair
Fast Metabolism (digestion) which causes some people to be very thin.
Increased or high levels of thyroid hormone causes hyperthyroidism,
Signs and symptoms:
Insomnia
fatigue
weight loss

7. The Endocrine System Parathyroid Glands
small, pea-shaped glands, located in the neck near the thyroid
produces parathyroid hormone – increases the level of calcium in blood

8. The Endocrine System Pancreas
a key gland located in the folds of the intestines
secretes several key digestive enzymes
Regulates the amount of sugar in blood.
Dysfunctional Pancreas can lead to too much sugar in the blood and cause diabetes

9. The Endocrine System Adrenal Glands
2 small glands that sit on top both kidneys.
the Adrenal glands secrete the hormones adrenaline which gives us the automatic response needed to “Fight or Flight” when in danger. This may result in increased heart rate and rate of breathing.

10. The Endocrine System
One thing to remember is that the Endocrine system is involuntary (automatic). We do not control it and tell it when do turn on or off. It is activated when necessary to help our bodies maintain normalcy. If we could control it, this would make it a voluntary body function.
