Izindlala ezakha uhlelo lwe-endocrine zikhiqiza izithunywa zamakhemikhali ezibizwa ngamahomoni ahamba egazini aye kwezinye izingxenye zomzimba.

Izindlala ezibalulekile ze-endocrine zifaka i-pituitary, i-thyroid, i-parathyroid, i-thymus nezindlala ze-adrenal.

Kunezinye izindlala eziqukethe izicubu ze-endocrine kanye ne-secrete hormone, kufaka phakathi amanyikwe, amaqanda kanye namasende.

Izinhlelo ze-endocrine nezinzwa zisebenza ngokubambisana. Ubuchopho buthumela iziyalezo ohlelweni lwe-endocrine. Ngokuphindaphindiwe, ithola impendulo engapheli evela kwizindlala.

Lezi zinhlelo zombili zibizwa ngokuthi uhlelo lwe-neuro endocrine.

I-hypothalamus iyi-switch switchboard enkulu. Kuyingxenye yobuchopho elawula uhlelo lwe-endocrine. Leso sakhiwo esilingana nepea silenga ngaphansi kwaso yindlala yepituitary. Ibizwa ngokuthi i-master gland ngoba ilawula ukusebenza kwezindlala.

I-hypothalamus ithumela imiyalezo ye-hormonal noma kagesi endleni ye-pituitary. Ngokulandelayo, ikhipha ama-hormone athwala amasiginali aye kwezinye izindlala.

Uhlelo lugcina ibhalansi yalo. Lapho i-hypothalamus ithola izinga lokukhuphuka kwamahomoni esithweni esihlosiwe, Ithumela umlayezo ku-pituitary ukuyeka ukukhipha ama-hormone athile. Lapho i-pituitary iyeka, ibangela ukuthi isitho esikhokhelwe siyeke ukukhiqiza ama-hormone aso.

Ukulungiswa okungaguquki kwamazinga ama-hormone kuvumela umzimba ukuthi usebenze ngokujwayelekile.

Le nqubo ibizwa nge-homeostasis.
