Endocrine system

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)
