Umzimba womuntu - luhlelo loluvumelanako lapho zonke izinqubo kulawulwa nomunye. Futhi njalo nomzimba ngezithako zawo kunomthelela silondoloze ubuqotho umsebenzi.

Kanye ubuchopho ingenye izindlela zokulawula ezibaluleke kakhulu - obuntu endocrine uhlelo. It lucwaningo isenzo sawo ngokuhlola endocrine nezindlala, okuyinto hormone unezici ezithile futhi tropism oluthize kuhlose amaseli. Ngakho, le ndlala yegilo linendima ebalulekile ekukhuleni komzimba futhi uhlale ithinta zonke izinhlobo exchange. Izimpande zakhe ama-hormone, ezinomthelela ngokomzimba, kwengqondo ezinganeni, ukunikeza umzimba namandla abadala. Ngakwelinye ihlangothi, ukukhiqizwa yabo kulawulwa isimiso sezinzwa, okungukuthi bioactive izinto pituitary futhi hypothalamic ukukhulula izici. Ngakho, ama-hormone egilo zihlale ezingeni elithile egazini futhi ukwandisa umzimba abanezidingo ezikhethekile, droppings yabo Ungase futhi kubonisa ukuntula umsebenzi yegilo iodine.

hormone

Glandula thyroidea (yegilo) unamathele kuqhoqhoqho kanye siqukethe sokunene nesobunxele iyizingxenye ezixhunywe isiqeshana sezwe. zamagama eqondile ama-hormone egilo wenziwa follicle kugcwele Colloid ngaphakathi, ogxile amaprotheni - thyroglobulin. Nge iodination obengeziwe tyrosine izinsalela e isimo sawo futhi summation okwalandela zezakhi etholwe futhi triiodothyronine kwakhiwa futhi tetraiodothyronine (T3 ne-T4). hormone tireiodnye Eminye ethathwe thyroglobulin-molecule wajinge wanamatsela bese abadedela emgudwini wegazi ngefomu khulula. Sinenkosi lokuhlala ehlukene, futhi ziyehluka potency (T3 imele ngemithamo aphansi, kodwa potency yayo mkhulu kakhulu kunalelo T4). Nokho, umphumela hormone emzimbeni ezifanayo: Ithuthukisa amanoni carbohydrate umzimba (kwenyuke namazinga kashukela egazini) inhlamvu gluconeogenesis, isibindi glycogen ekuvimbeleni ukwakheka kanye ukuthuthukisa amaprotheni zamagama (e isamba ngokweqile, Ngakolunye uhlangothi, ukuthuthukisa nokuwohloka yokugcina).

It livezwa yokuthi sigcine igazi wegazi nokushaya kwenhliziyo kuyehla futhi izinga lokushisa komzimba, ukusheshisa izinqubo ngokwengqondo nangokomzwelo. Ngo -embryonic period hormone egilo banesibopho kwamangqamuzana ka ezicutshini zawo wonke umzimba. Ngo ebuntwaneni, laba kanjani nesandla ekukhuleni nokuthuthukiswa nangokwengqondo wengane. Ngaphezu kwalokho, ukuthuthukisa erythropoiesis, reabsorption aphansi ijabulise yamanzi.

isifo

Kwezinye izifo, indlala yegilo i-hormone uketshezi kuyehla (i-hypothyroidism). Kulokhu, kufanele bafaka yimithi. Lokho liyakwazi ukuntuleka izakhi kokuqukethwe okufana BAKC ama-hormone egilo? Izidakamizwa asetshenziswa Kulokhu - kuyinto "Levothyroxine" (T4), "Liotironin" (T3) futhi ezihlukahlukene izidakamizwa iodine-equkethe. Njengoba nokubi futhi ama-hormone egilo ngokweqile kungaholela iziyaluyalu umzimba emzimbeni ukuthi kukhona ukwephulwa emtholampilo obusobala homeostasis futhi lengqondo umsebenzi. I degree of umonakalo incike yobudala lesiguli (cretinism kuphela izingane), ezingeni ukushoda noma ngokweqile kwama-hormone (i-hyperthyroidism 1, 2, 3 degrees). Ekugcineni kukhona iphika, palpitations, kukhuphuke blood pressure, iziyaluyalu zonke izinhlobo exchange. Nge ukuntula, kunalokho, kwehle umzimba, isiguli kuba evilaphayo, ngabandayo.
