Let’s take a look at some of the major endocrine glands and the functions of their hormones. Your body also needs a strong blood supply to transport the hormones throughout the body. The endocrine system regulates vital processes in the body including growth, metabolism, and sexual development. A hormone is a chemical that is made by specialist cells, usually within an endocrine gland, and it is released into the bloodstream to send a message to another part of the body. stream They’re responsible for almost every cell, organ, and function in your body. Critical evaluation of endocrine sensitive tissues such as mammary glands and reproductive organs provides particularly important information about the nature of changes in endocrine organs. Some organs, such as the stomach, intestines, and heart, produce hormones, but their primary function is not hormone secretion. The body makes more than 20 hormones, each with a specific function. A further characteristic is that the endocrine glands and cell groups are occupied exclusively with the formation and secretion of their hormones. Endocrine Glands and Hormones - Hypothalamus, Pituitary Gland, Pineal Gland, Thyroid Gland, Parathyroid Gland, Thymus, Adrenal Gland, Pancreas, Testis, Ovary, Mechanism of Hormone Action. One of the major function of the pancreas is maintaining appropriate levels of sugar throughout the body. Endocrine system glands are spaced throughout the entire body. They are ductless glands and their secretions are called hormones. Course Hero is not sponsored or endorsed by any college or university. The messenger molecules of the endocrine system are called endocrine hormones. The pituitary controls the rate at which it secretes hormones through a feedback loop in which the blood levels of other endocrine hormones signal the pituitary to slow down or speed up.

Adrenal Glands and its hormones There are 2 adrenal glands that lie anteriorly to kidneys. Pituitary activity is regulated by hormones of the hypothalamus, a brain region connected to the pituitary by the pituitary stalk. Their secretions are called hormones.

ENDOCRINE SYSTEM Hormones are the body’s chemical messengers and are part of the endocrine system. Although there are endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships. The thyroid gland is found in the neck, below the thyroid cartilage (which forms “Adam’s apple”). (Note: endocrine shouldn’t be confused with exocrine.
