Njengoba abantu endocrine uhlelo ulawula izinqubo zangaphakathi emzimbeni.

Uhlelo endocrine kuyinto umuntu kanye isimiso sezinzwa elawula izinqubo ezibalulekile emzimbeni, babanike okuthiwa isiqondiso humoral nokugcina homeostasis kuwo, okungukuthi, ibhalansi kwangaphakathi. Okunjalo izindlela zangaphakathi kwezokwelapha uhlola ngokuningiliziwe Endocrinology isayensi. I engavamile zemizimba ukuthi ahlanganisiwe welithi "womuntu endocrine uhlelo" wukuthi abanayo Amapayipi excretory phakathi komgodi umzimba. Laba balimi bafakela umphumela uketshezi yayo, noma hormone, ngqo igazi lymph uketshezi, ngokungafani nezindlala exocrine, kuxhunyanwa ezihlukahlukene izimbotshana umzimba futhi imvelo bangaphandle.

Uhlelo endocrine yomuntu ihlukile kwezinye izinhlelo komzimba "ezikude" yakhe. Lokhu kusho ukuthi control on the ingxenye yomzimba Kwenziwa hhayi ezindaweni zokukhiqiza izidakamizwa ezifana ayisiphekupheku, njengomoya amahomoni, kude kakhulu kuzo. Ngokwesibonelo, ama-hormone antidiuretic ikhiqizwa indlala pituitary esemgwaqweni ugebhezi, nezenzo zabo phezu tubules kwezinso. Ngokufanayo oxytocin. Libuye libe indawo umkhiqizo neurohypophyseal kule ingaphakathi cranial, futhi yindawo kwesicelo - ke ezicutshini lesizalo.

Uhlelo endocrine, umuntu ngamunye abe isitebhisi phezulu. Zonke nezindlala yangaphakathi ukukhiqiza ama-hormone zabo ethize, angaphansi ithonya uhlelo hypothalamic-pituitary, engaphansi kweso umsebenzi sezinzwa futhi cortical izakhiwo ingqondo. Pituitary indlala - isixhumanisi phakathi nezindlala we ezingeni leliphasi kanye le ngxenye. Lesi sakamuva, niqonda izitshengiselo ezivela kwamanye isimiso sezinzwa ukhiqiza "hormone kukhululwa" okwakuyokwenzeka (ama-statin futhi liberiny) ezithinta amaseli pituitary ngibabuyisele secrete noma anda noma ukunciphisa uketshezi hormone utho. hormone Tropic of the pituitary anterior futhi kungithinte ihadiwe sokugcina. Ngokwesibonelo, i-hormone yegilo-inkanuko kuthinta kuphela izicubu yezindlala we indlala yegilo futhi i-hormone lactotropic phezu webele. Siphetfo mthethonqubo kuyinto ukuthuthukiswa esingaguquguquki hormone esifanele, ngegazi kanye lymph ezithinta umzimba, ukukhula, ukudla kanye nokuthuthukiswa nezinye izitho neenkambiso.

Ngokusho isakhiwo yabo zamakhemikhali, zonke hormone zingahlukaniswa ngamaqembu ezine eziyinhloko: glycoprotein, amaprotheni-peptide, steroid nama-amino acid. Zingabonisa (njengoba kushiwo ngenhla) ehlukaniswa wesenzo ngokomzimba. Hypothalamic futhi hormone pituitary ayaqala hormone, nabo bonke abanye - ukuba nabadlali. Ukuqala lokulawula hormone ekusebenziseni.

Endocrine uhlelo kakhulu eziphula ibhalansi emzimbeni. Kusukela ezingeni lesion kuzoncika ethile isithombe emtholampilo. Iphinde kungathinta ubunjalo uketshezi okungavamile kwezinto eziphilayo. Endocrine Pathophysiology at izifo yayo ezahlukene ezifana ukuthi uma umzimba ephawulwe ukwehla uketshezi of hormone ke isifo ke kuyodingeka ngendlela nokushoda yayo sibi, futhi, ngokufanelekile, okuphambene nalokho. Isibonelo myxedema noma i-hypothyroidism, is kakhulu ziyancipha lapho yegilo umsebenzi futhi okuphambene yayo goiter thyrotoxic nge ukukhiqiza ngokwedlulele kwama-hormone egilo.

Uhlelo endocrine yomuntu, naphezu ukuthuthukiswa yimpumelelo futhi okusheshayo imithi kanye ne-nanotechnology, namanje wafunda ngokugcwele nokwakheka izitho zomzimba. Nokho, lokho kakade aziwa isayensi, okuvumela odokotela-endocrinologists imatasa ukwelashwa kanye nokuvimbela izimo zokucabanga okubangelwa isifo izimpilo zayo iziguli okwenza 'ngokunethezeka futhi kangcono.
