The Endocrine System and Discrete Endocrine Organs

trenchant organs, such as the hypophysis and the thyroid, argon constituents of a macro and intrinsic system of ductless glands, commonly referred to as internal secretion glands. However, several non-distinct organs similarly give birth hormone threads and assist like internal secretion glands, and washstand 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 present their hormones directly into the blood stream, bypassing some(prenominal) sort of exocrine characterized, waxy framework. The true, discrete organs of the endocrine system include the future(a) glands: The hypothalamus, pituitaries, pineal, thyroid and para-thyroid and the adrenals. The non-discrete endocrine organs, those which possess endocrine tissues, include the adjacent: The gastrointestinal and respiratory tracts, pan creas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located profoundly within the brain, thus rout out be considered discrete or non-discrete. Additionally, and for practical reasons, several of the non-discrete organs with endocrine tissues are evidently referred to as endocrine organs, e.g. the endocrine pancreas, or the endocrine heart.\nThe endocrine glands release of hormones, which is finely adjust and coordinated, provides homeostatic stability passim the body. This stabilization, in turn, ultimately enhances the numerous mammalian functions that must choke every day of our lives. The epithelial cells of endocrine tissues are exceedingly active; generally, these cells present conspicuously stained nuclei and cytoplasmic organelles. The mitochondria, Golgi bodies, secretory granules and endoplasmic reticulum are the important contributors to the cells prominent cytoplasmic detection character. Two general types of hormones are produce d and secreted from endocrine g... If you want to possess a full essay, order of magnitude it on our website:
