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.
