Osmosis video - Endocrine system anatomy and physiology

The endocrine system comprises all endocrine organs, which produce various hormones in the body. Hormones are like chemical messengers, which travel in the blood to arrive at their receptors, where they initiate action.

Organs of the endocrine system include the hypothalamus, pituitary gland, thyroid gland, parathyroid gland, adrenal glands, pancreas, and Gonads (ovaries and testes). Each gland releases specific hormones that help regulate everything from hunger and thirst to blood pressure and reproduction.
