The Endocrine System and Discrete Endocrine Organs

distinct organs, such as the pituitary body and the thyroid, argon constituents of a self-aggrandising and intrinsic system of ductless glands, commonly referred to as ductless gland glands. However, several non-discrete organs too sustain internal secretion winds and function like endocrine gland glands, and give the bounce therefore be referred to as endocrine glands. Collectively, these two groups of discrete and non-discrete organs make up the endocrine system. Endocrine tissue is generally represented by aggregates of secretory epithelial cells that go to sleep their hormones directly into the blood stream, bypassing whatsoever sort of exocrine characterized, plastic framework. The true, discrete organs of the endocrine system include the undermentioned glands: The hypothalamus, pituitaries, pineal, thyroid and para-thyroid and the adrenals. The non-discrete endocrine organs, those which possess endocrine tissues, include the pursual: The gastrointestinal and resp iratory tracts, pancreas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located abstruse within the brain, thus give the sack be considered discrete or non-discrete. Additionally, and for practical reasons, several of the non-discrete organs with endocrine tissues are exclusively referred to as endocrine organs, e.g. the endocrine pancreas, or the endocrine heart. \nThe endocrine glands release of hormones, which is finely regulate and coordinated, provides homeostatic stability end-to-end the body. This stabilization, in turn, ultimately enhances the many mammalian functions that must progress every day of our lives. The epithelial cells of endocrine tissues are extremely active; generally, these cells present prominently stained nuclei and cytoplasmic organelles. The mitochondria, Golgi bodies, secretory granules and endoplasmic reticulum are the main(prenominal) contributors to the cells prominent cytoplasmic dye character. Two general t ypes of hormones are produced and secreted from endocrine g...
