Endocrine Glands (Gr. Endon - Inside, Krinane - Separate)

Endocrine glands (Gr. endon - inside, crinein - to separate) are internal secretion organs that secrete into the blood or lymph substances called hormones that specifically act on other organs or parts of the body. Hormones produced by endocrine glands play an important role in the regulation of many biological processes in the body, such as growth, development, metabolism, reproductive function and others.

The endocrine glands include the thyroid gland, parathyroid glands, adrenal glands, pancreas, pituitary gland, pineal gland and gonads. Each of these glands produces its own set of hormones that regulate the functioning of specific organs and systems of the body.

The thyroid gland secretes hormones necessary for the proper functioning of energy metabolism, growth and development of the body, as well as for the regulation of metabolism and body temperature.

The parathyroid glands are responsible for the level of calcium and phosphorus in the blood, regulating the functioning of bones and muscles
