endocrine glands
Endocrine glands secrete hormones directly into the blood stream to regulate various physiological processes in the body.
Endocrine glands secrete hormones and neuropeptides into interstitial fluid and the blood stream.
Because an endocrine glad does not have a tube through which it delivers hormone to the body. They just release their hormones into the space around the gland, which diffuse into the blood stream.
Endocrine glands are ductless organs or groups of cells that secrete hormones directly into the bloodstream. These hormones travel through the bloodstream to target organs and tissues, where they regulate various physiological processes and responses in the body. Examples of endocrine glands include the thyroid, pancreas, and adrenal glands.
Endocrine glands secrete chemicals called hormones directly into the bloodstream, influencing the activity of the muscles and organs.
The glands in this category secrete their products, the hormones, into the blood stream, rather than via ducts. They have no ducts. In contrast, the salivary glands secrete saliva into the mouth cavity, rather than the blood stream. These are exocrine glands.
Your endocrine gland is consist of a system of glands with the main glands called the pituitary gland, pancreas, ovaries and testes, thyroid gland, and the adrenal glands.
ALL hormones by definition are secreted directly into the blood stream (and hence without the use of a duct). Glands that produce them are called endocrine glands. Major endocrine glands include the pituitary, thyroid, adrenal and pineal glands. Glands such as the pancreas have a "dual" function in that they secrete via a duct (exocrine function) as well as secreting hormones (endocrine function).
They are ductless so they secrete chemicals directly into the blood stream.
Hormones are secreted by ductless glands, hence they enter directly into the blood stream which carries it to the targeted organ.
The generic term for glands that empty into a duct or onto a body surface are called exocrine glands. Glands the release their secretions directly into the blood stream are called endocrine glands.
Directly into the Blood Stream. Endocrine Glands release there secretions (hormones) directly into the blood stream. That is why they are unlike Exocrine Glands.
