 Made up of all glands and hormones of the body  Stimulated by nervous system, chemical receptors, and other hormones.  Glands secrete hormones  Regulates homeostasis

 Adrenal gland  Hypothalamus  Pancreas  Ovaries (f)/Testicles (m)  Parathyroid gland  Pineal gland  Pituitary gland  Thymus gland  Thyroid gland

 Adrenal Cortex creates hormones to: -break down proteins -reduce inflammation -regulate mineral ions -regulate growth  Adrenal Medulla creates hormones to increase blood flow to brain and muscles during a “fight or flight” response

 Part of the nervous system  Specialized neurons influence hormone production  Controls other hormone producing organs/glands by releasing stimulating hormones

 Serves functions as endocrine organ and exocrine organ  Produces the hormone insulin to regulate blood sugar levels.

 Ovaries create the female sex hormones  Estrogen develops female secondary sex characteristics and basic growth.  Progesterone maintains a suitable environment for an egg during ovulation.  Testicles produce male sex hormones.  Testosterone induces growth and development of male muscles, bones, and sex organs.

 Located on the posterior side of the thyroid gland  Produces the hormone parathyroid hormone  Regulates calcium levels in blood, bones, and kidneys

 Located near the thalamus in the brain.  Produces melatonin to regulates human circadian rhythm (sleep-wake cycle)  Triggered by photoreceptors to only produce Melatonin in low light conditions.

 Made up of 2 parts: -anterior -posterior  Posterior section is part of Hypothalamus that regulates water levels in the body and aspects of pregnancy.  Anterior region produces growth hormones and hormone stimulating hormones.

 Prepares the body for growth during fetal development.  Helps defend the body from pathogens.  Stops being active during puberty and eventually gets replaced by adipose tissue.

 Located at base of neck around trachea.  Produces three different hormones: Calcitonin, T3, and T4  Regulates calcium levels if they get too high and metabolic activities.

 During a fight-or-flight response, blood flow from the cardiovascular system is increased to the muscular and nervous system.  Digestion and blood sugar levels are regulated by hormones produce by the endocrine system.  Calcium levels in bones and steady growth produced by the skeletal system are also regulated by hormone releasing gland.

 Reproductive organs and pregnancy are affected by glands in the endocrine system.  Aiding the immune and lymphatic systems that are fighting disease, the endocrine system reduces inflammation in parts of the body.

 Diabetes is a disease related to the lack of production of insulin.  Without insulin, the body has no way to monitor and regulate blood sugar levels.  If not monitored, this disease could possibly be fatal by either having too high or too low blood sugar.

 The Hypothalamus is what makes you hungry and/or thirsty.  The endocrine system can directly affect human behavior.  There are a total of 30 different hormones in the human body.

 Pick a partner  One of you will be allowed to pick up functions, the other will pick up organ names.  Coordinate with your partner to bring me the correct pairs first.  If you get one wrong you start all over.
