Amadlala enza inkqubo ye-endocrine avelisa abathunywa bemichiza abizwa ngokuba zihomoni ezihamba egazini ziye kwamanye amalungu omzimba.
Izibilini ze-endocrine zibandakanya i-pituitary, i-thyroid, i-parathyroid, i-thymus kunye ne-adrenal gland.
Kukho amanye amadlala aqukethe izicwili ze-endocrine kunye ne-secrete hormone, kubandakanya i-pancreas, ii-ovari, kunye ne-testes.
Inkqubo ye-endocrine kunye ne-nervous isebenza ngokubambisana. Ingqondo ithumela imiyalelo kwinkqubo ye-endocrine. Ukubuya, ifumana ingxelo rhoqo evela kumadlala.
Ezi nkqubo zimbini zidibeneyo zibizwa ngokuba yinkqubo ye-neuro endocrine.
Ihypothalamus yibhodi yokutshintsha. Yinxalenye yengqondo elawula inkqubo ye-endocrine. Esi sakhiwo silingana nepea esixhonywe ngaphantsi kwaso yindlala yebhinqa. Ibizwa ngokuba yi-master gland kuba ilawula ukusebenza kwamadlala.
Ihypothalamus ithumela imiyalezo yehomoni okanye yombane kwindlala yebhinqa. Emva koko, ikhupha iihormoni ezithwala imiqondiso kwamanye amadlala.
Inkqubo igcina ibhalansi yayo. Xa i-hypothalamus ifumana inqanaba lokunyuka kwamahomoni kwilungu ekujoliswe kulo, Ithumela umyalezo kwi-pituitary ukuba iyeke ukukhupha iihomoni ezithile. Xa i-pituitary iyeka, ibangela ukuba ilungu ekujoliswe kulo liyeke ukuvelisa iihomoni zalo.
Uhlengahlengiso oluqhubekayo lwamanqanaba ehomoni avumela umzimba ukuba usebenze ngendlela eqhelekileyo.
Le nkqubo ibizwa ngokuba yi-homeostasis.
