Eyona ezisemqoka okuluphawu inkqubo yonyango yabantu

Umzimba womntu usekela umsebenzi wayo phezu intsebenziswano egudileyo inani elikhulu iiseli, ancedisana amalungu ukuba abe izakhiwo ezahlukeneyo kunye nenjongo esebenza. Ukuze kuphunyezwe lo intsebenziswano ngethuba ngendaleko izinto eziphilayo yenziwe iqela iindlela zebhayoloji abalawula umsebenzi wamalungu zangaphakathi kwaye ukulungelelanisa umsebenzi wabo kwi ukutshintsha iimeko zangaphandle nangaphakathi. iindlela ezinjalo ziquka inkqubo yonyango le ndoda.

Isenzo inkqubo yonyango

Isenzo amalungu ezidalwe isekelwe phezu imveliso yezinto ezizodwa esebenzayo - iihomoni. Kuye nolwalamano olusenyongweni kunye nokusebenza kwenkqubo luvo emzimbeni. Le ngxenye uvelisa corticotropin, ekhuthaza ingqondo yebhinqa ukumkhulula corticotropin. Ukuphendula, kwamadlala ezidalwe ndimlahlele phandle igazi iihomoni corticosteroid. Inqanaba le hormone Oluphawu ukumana kujongwa kuyo kwixesha luvo kudaleke inkqubo yonyango. Hormone ukungena ukuba iiseli nge kwisithuba extracellular okanye imithambo yegazi. Iiseli ecingela hormone kufuneka receptors zabo ethile komhlaba. Ezi ezenza bakwazi ukuqonda nokuba imali encinane kweziyobisi hormone kwaye ukunxibelelana ngayo ukuba utshintsho intracellular.

Amalungu inkqubo yonyango abantu

Kukho imizimba eziliqela unoxanduva lokuyila hormone. Ukongeza, ezintweni ezininzi mzimba iiseli ezikhethekileyo langoku, enza secretion kwezinto hormone. Kule nkalo, le nkqubo yonyango lungohlulwa lube iinxalenye ezimbini: glandular kunye kwentamo. Inxalenye yokuqala iquka kwamadlala yonyango. Ngokomzekelo, ezifana esinobubovu adrenal, injeke, isini, lengqula kunye ingaba parathyroid. ifomu yingxenye kwentamo iiseli ezidalwe eyahlukileyo ibekwe kwizihlunu ezahlukeneyo wonke umzimba.

Eyona engundoqo imisebenzi yenkqubo yonyango

Hormone secreted egazini, yenze le misebenzi ilandelayo:

1. Thatha inxaxheba ngayo kwemichiza komzimba.
2. Unxibelelaniso lwemisebenzi ezidibeneyo ngamalungu zangaphakathi.
3. Iimpembelelo ukukhula ephilayo kunye nokuqinisekisa uphuhliso lweenkqubo zawo zonke. Umzekelo, ukukhuthaza ukufunxeka calcium kunye nokukhula amathambo.
4. umahluko ngokwesini kunye nemisebenzi zokuzala. Gonads kunye neuron adrenal, nazo zibandakanywe kwinkqubo yonyango, abelwe izinto ezinika ukuyilwa zamabanga aphantsi kunye neempawu zesini eziziisekondari.
5. Ukulungiswa ephilayo utshintsho lobume. Umzekelo iqela ukwimo catecholamine ezifana epinephrine. Ezichaphazela izinga intliziyo, ukubila, bronchiectasis.
6. Impembelelo kurhulumente yezengqondo zengqondo nezokuziphatha iinkalo zezinto ezenziwa luluntu. Umzekelo, iihomoni glucocorticoid kunokubangela umntu euphoric, kodwa intsalela kukhokelela okukhulu.
