Endocrine System

Glands & Hormones


Hormone
Hormone

A chemical messenger that is produced at one site and carried by the blood to its site of action (target cells)


Pituitary gland
Pituitary Gland

1.ACTH (Adrenocorticotropic hormone) Stimulates adrenal glands to make Cortisol and aldosterone

2.ADH (Antidiuretic hormone) Causes kidneys to reabsorb more water preventing dehydration

3.GH (Growth hormone) (Causes bone and muscle growth)

4.TSH (Thyroid stimulating hormone) (Stimulates thyroid gland to make T3 and T4)


Pituitary gland1
Pituitary Gland

5. LH (Luitenizing hormone) (Stimulates estrogen & progesterone secretion from ovaries & testosterone secretion from testes)

6. FSH (Follicle stimulating hormone) (Egg & sperm production)

7.    Oxytocin (Causes uterine contractions)

8.Prolactin (milk production)


Pineal gland
Pineal Gland

  • Melatonin (Initiates sleep)


Thyroid gland
Thyroid Gland

T3 (Triiodothyronine) (Controls metabolism)

T4(Thyroxin) (Controls metabolism)

  • Calcitonin (Builds up bone to lower blood calcium)


Parathyroid gland
Parathyroid Gland

  • PTH (Parathyroid hormone) (Breaks down bone to raise blood calcium)


Thymus gland
Thymus Gland

  • Thymosin (Controls immune system)


Pancreas
Pancreas

  • Insulin (Allows glucose to enter cells; LOWERS blood glucose)

  • Glucagon (Stimulates liver to make glucose; RAISES blood glucose)


Adrenal glands
Adrenal Glands

Medulla

a.Epinephrine (adrenaline) (Increases: blood glucose, heart rate, blood pressure, breathing rate, & dilates bronchioles)

b.Nor-epinephrine (nor-adrenaline) (Same as Epinephrine)


Adrenal glands1
Adrenal Glands

Cortex

a.Cortisol (Stress released to increase blood glucose)

b.Aldosterone (Controls salt & water balance)

c.Androgens (small amounts of estrogen and testosterone)


Ovaries
Ovaries

  • 1.Estrogen (Creates female secondary sex characteristics)

  • 2.Progesterone(Thickens the uterus lining each month)


Testes
Testes

  • 1. Testosterone (Creates male secondary sex characteristics)


Kidneys
Kidneys

  • Renin and Angiotensinogen which control blood volume


Heart
Heart

  • ANP (Atrial Naturetic Polypeptide) which causes Na ions to be excreted in the kidney (Lose water & ultimately blood pressure)
