Endocrine Systematics
Barrett PetersBiomedical Research
Function and Format Made up of all glands and hormones of
the body Stimulated by nervous system,
chemical receptors, and other hormones.
Glands secrete hormones Regulates homeostasis
Organs/Peripherals Adrenal gland Hypothalamus Pancreas Ovaries (f)/Testicles (m) Parathyroid gland Pineal gland Pituitary gland Thymus gland Thyroid gland
Adrenal 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
Hypothalamus Part of the nervous system Specialized neurons influence hormone
production Controls other hormone producing
organs/glands by releasing stimulating hormones
Pancreas Serves functions as endocrine organ
and exocrine organ Produces the hormone insulin to
regulate blood sugar levels.
Ovaries/ Testicles 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.
Parathyroid Gland Located on the posterior side of the
thyroid gland Produces the hormone parathyroid
hormone Regulates calcium levels in blood,
bones, and kidneys
Pineal Gland 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.
Pituitary Gland 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.
Thymus Gland 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.
Thyroid Gland 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.
Relation to other systems 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.
Relation (cont.) 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 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.
Fun Facts 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.
GAMETIME!!! 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.
