Endocrine System

Cassie Ethridge

Organs of the Endrocrine System

Pineal Gland

>Function: Maintain circadian rhythm and regulate reproductive hormones

>Hormones Made Here: Melatonin


>Function:Helps to maintain homeostasis

>Hormones Made Here: Anti-diuretic Hormone, Oxytocin

Pituitary Gland

>Function: Help regulate the functions of other endocrine glands

>Hormones Made Here: Adrenocorticotropic Hormone(ACTH), Follicle-stimulating Hormone(FSH), Growth Hormone(GH), Luteinizing Hormone(LH), Prolactin(PRL), Thyroid Stimulating Hormone(TSH), Anti-diuretic Hormone(ADH), Oxytocin

Thyroid Gland

>Function: Regulate your metabolism

>Hormones Made Here: Thyoxine(T4), Triiodothyronine(T3), Calcitonin

Parathyroid Gland

>Function: Regulate's the body's calcium levels

>Hormones Made Here: Parathyroid Hormone(PTH)

Thymus Gland

>Function: Produce thee hormone of the thymus, that stimulates the development of disease-fighting T cells

>Hormones Made Here: Thymosin

Adrenal Gland

>Function: produce hormones that help the body control blood sugar, burn protein and fat, react to stressors and regulate blood pressure

>Hormones Made Here: Glucocorticoids, Mineralcorticoids, small amounts of estrogen and testosterone, Epinephrine, norepinephrine


>Function: Maintain the health of the female reproductive system

>Hormones Made Here: Estrogen and Progesterone


>Function: In childhood, physical development. In adulthood libido, muscle strength and bone density

>Hormones Made Here: Testosterone

Let's Take a Look at the Organs

The Roles of the Hormones

1. Melatonin

>Produced: Pineal Gland

>Role: To help control your circadian rhythm and regulate certain reproductive hormones

2. Oxytocin

>Produced: Hypothalamus, Pituitary Gland

>Role: A variety of things includding the ability to trust, body tempurature, sleep cycles, and the release of breast milk. Considered the happiness hormone

3. Antidiuretic(ADH)

>Produced:Hypothalamus, Pituitary Gland

>Role: Increase water absorption into the blood by the kidneys

4. Growth Hormone(GH)

>Produced: Pituitary Gland

>Role: In childhood, aintaining healthy bone compostition and growth. In adult, aids in healthy bone and muscle mass, along with affecting fat distribution

5. Prolactin(PRL)

>Produced: Pituitary Gland

>Role: Stimulates breast milk production

6. Follicle Stimulating Hormone(FSH)

>Produced: Pituitary Gland

>Role: Works with Luteinizing Hormone to ensure normal functioning of the ovaries and testes

7. Luteinizing Hormone(LH)

>Produced: Pituitary Gland

>Role: Works with Follicle-stimulating Hormone, to ensure normal functioning of te=he ovaries and testes

8. Thyroid Stimulating Hormone(TSH)

>Produced: Pituitary gland

>Role: Stimulates the thyroid to produce hormones

9. Adrenocorticotropic Hormone(ACTH)

>Produced:Pituitary Gland

>Role: Stimulates the adrenal glands to produce horomones

10. Thyroxine(Tsub4)

>Produced: Thyroid Gland

>Role: Stimulate the consumption of oxygen, and metabolism of cells and tissues in the body

11. Triiodothyronine(Tsub3)

>Produced: Thyroid Gland

>Role: Regulates tissue metabolism

12. Calcitonin

>Produced: Thyroid Gland

>Role: Controls blood calcium levels

13. Parathyroid Hormone(PTH)

>Produced: Parathyroid Gland

>Role: Regulates body's calcium level, Increases the formation of active Vitamin D

14. Thymosin

>Produced: Thymus Gland

>Role: Stimulates the development of T cells, a type of white blood cell

15. Epinephrine

>Produced: Adrenal Gland

>Role: Hormone that rapidly responds to stress, can spike blood sugar levels

16. Norepinephrine

>Produced: Adrenal Gland

>Role: Hormone that works with Epinephrine, can increase blood pressure

17. Glucocorticoids

>Produced: Adrenal Gland

>Role: Regulation of blood pressure, and cardiovascular function. Regulate immune response and suppress inflammatory reactions.

18. Mineralocorticoids

>Produced: Adrenal Gland

>Role:Maintain the balance of salt and water, while controlling blood pressure

19. Insulin

>Produced: Pancreas

>Role: Regulates blood glucose, by allowing cells to absorb glucose

20. Glucagon

>Produced: Pancreas

>Role: Regulates blood glucose, by stimulating cells to release glucose

21. Testosterone

>Produced: Testes and small amount in the Adrenal Gland

>Role: Primary hormone in the proper physical development in boys, including healthy development of male sex organs, growth of facial and body hair, lowering of the voice, increase in height, increase in muscle mass, and growth of the Adam's apple. In adult hood, maintains libido, sperm production, maintaining muscle mass and mass, promoting healthy bone density

22. Estrogen

>Produced: Ovaries and small amount in the Adrenal Gland

>Role: Instrumental in breast development, fat distribution and the development of reproductive organs

23. Progesterone

>Produced: Ovaries/Corpus Luteum

>Role: Causes the uterine lining to thicken

What's the difference between the Endocrine and Exocrine?

The main noted in the names of the two systems. Endocrine had the prefix endo- meaning inside. Exocrine has the prefix exo- meaning outside. Exocrine glands release to outside the body, while Endocrine glands release to inside the body.
