SYSTEM
• The endocrine system uses chemicals to control many systems and functions in your body
• Endocrine glands are the tissues of the endocrine system found throughout the body
• Hormones are the chemicals produced in endocrine glands
• The endocrine glands release hormones directly into the blood
ENDOCRINE GLANDS:
* Pineal gland – deep in the brain- produces melatonin- regulates sleep patterns
* Pituitary gland - attached to the hypothalamus in the forebrain
- affects growth, reproduction, and the functions of other glands
• Thyroid gland – below the larynx- regulates metabolism- promotes development of the
nervous system
• Parathyroid - attached to the thyroid- regulate calcium levels in the
body
• Thymus - in the upper chest- hormones produced in the thymus
stimulate the production of cells that fight infection
• Adrenal glands – on top of each kidney- produce a variety of hormones- help your body adapt to
physical and emotional stress (fight or flight)
• Pancreas - behind the stomach- produces insulin- controls sugar levels in the blood
• Testes (in males) – produce testosterone - controls the development of male sex traits - plays a role in sperm production
• Ovaries (in females) – produce estrogen and progesterone- control the development
of female sex traits- regulate the female reproductive cycle
