ENDOCRINE SYSTEM
Definition
The endocrine system is a network of
glands in the body that produce and
release hormones. These hormones
regulate many important bodily
functions, such as growth,
metabolism, sexual development,
mood, and homeostasis (the body’s
internal balance).
, NAME OF ALL ENDOCRINE
GLANDS
1. Pituitary Gland – called the “master gland”;
controls other endocrine glands.
2. Hypothalamus – links the nervous system to
the endocrine system; controls the pituitary
gland.
3. Pineal Gland – produces melatonin (regulates
sleep-wake cycle).
• 4. Thyroid Gland – controls metabolism,
energy, and growth.
, NAME OF ENDOCRINE GLANDS
5. Parathyroid Glands (usually 4) – regulate
calcium and phosphorus levels.
6. Adrenal Glands – produce adrenaline, cortisol,
and aldosterone.
7. Pancreas – has both endocrine and exocrine
functions; regulates blood sugar (insulin and
glucagon)
8. Ovaries (in females) – produce estrogen and
progesterone.
• 9. Testes (in males) – produce testosterone.
