• Works with T4 to control metabolism

• Increases blood sugar levels

• Stimulates the immune system

• Regulates calcium levels in bones

Endocrine System Function

• Communication and control through electrical signals

• Communication and control through chemical signals called hormones

• Regulation of body temperature through sweat

• Digestion and absorption of nutrients in the intestines

Leptin

• A hormone that increases hunger

• A type of protein found in muscle cells

• A neurotransmitter that regulates mood

Pancreas

• Produces insulin and glucagon; has both endocrine and exocrine functions

• Produces bile and aids in digestion

Posterior Pituitary

• Stores and releases ADH and oxytocin

• Produces insulin and glucagon

• Regulates metabolism and energy levels

• Controls heart rate and blood pressure

Adrenal Medulla

• Secretes cortisol and aldosterone

• Secretes epinephrine and norepinephrine

• Produces insulin and glucagon

• Releases growth hormone and prolactin

Thyroid-Stimulating Hormone (TSH)

• Stimulates thyroid to produce thyroxine

• Inhibits thyroid hormone production

• Regulates calcium levels in the blood

• Stimulates adrenal gland function
