Izinto eziyinhloko agcwele abantu endocrine uhlelo

Umzimba womuntu usekela umsebenzi yayo phezu ukuxhumana abushelelezi inqwaba amaseli, izicubu kanye izitho ukuthi babe izakhiwo ezahlukene kanye injongo sokusebenza. Ukuze sikwazi ukufeza lokhu ukuxhumana phakathi kwemvelo eziphilayo sidaliwe izinto eziningi ezisebenza ngokubambisana yemvelo elawula umsebenzi izibilini ezihambelana umsebenzi wabo ukuze izimo zangaphakathi nezangaphandle kokushintsha. izindlela ezinjalo zihlanganisa i-endocrine uhlelo indoda.

Isenzo kohlelo endocrine

Isenzo endocrine izitho kusekelwe ukukhiqizwa izinto asebenzayo ekhethekile - hormone. It has a ubuhlobo obuseduze ukusebenza isimiso sezinzwa somzimba. Le ngxenye ukhiqiza corticotropin, ekhuthaza indlala pituitary ukudedela corticotropin. Besabela kuleso simemo, izindlala endocrine ukuxosha igazi hormone ngama-corticosteroid. Izinga yalezi isignali hormone liyireferensi iphuzu sezinzwa kuvusa uhlelo endocrine. Kuthiwa ama-hormone ukungena amaseli ngokusebenzisa isikhala extracellular noma ngokusebenzisa imithambo yegazi. Amaseli sensitive kukhona nama-hormone ube surface yabo receptor ethize. Lezi mangqamuzana ezinzwa uyakwazi ukubona ngisho esincane i-hormone izidakamizwa kanye nabo ukuze abangele izinguquko intracellular.

Izinhlaka ohlelweni endocrine wabantu

Ikhona nemizimba eziningana obhekene ekukhiqizweni kwama-hormone. Ngaphezu kwalokho, ezicutshini eziningi emzimbeni namangqamuzana akhethekile akhona, enza uketshezi izidakamizwa hormone. Kule ndaba, ohlelweni endocrine kungenziwa ihlukaniswe yaba izingxenye ezimbili: i-yezindlala kanye ehlasela umzimba. Ingxenye yokuqala kuhlanganisa nezindlala endocrine. Ngokwesibonelo, ezifana le ndlala adrenal, amanyikwe, ubulili, yegilo kanye indlala parathyroid. Ehlasela umzimba okuyingxenye ifomu elihlukile endocrine amaseli etholakala izicubu ahlukahlukene wonke umzimba.

Imisebenzi esemqoka ohlelweni endocrine

Kuthiwa ama-hormone akhishelwa egazini, afeze imisebenzi elandelayo:

1. Bamba iqhaza ukusabela kwamakhemikhali emzimbeni.
2. Coordination imisebenzi ngokuhlanganyela yezitho zangaphakathi.
3. Umthelela on ukukhula umzimba futhi ukuqinisekisa ukuthuthukiswa kwazo zonke izinhlangano zawo. Ngokwesibonelo, ukukhuthaza ukumuncwa kwe-calcium ukukhula amathambo.
4. umehluko ngokocansi nemisebenzi zokuzala. Gonads futhi cortex adrenal, okuyinto zifakwe ohlelweni endocrine, onikezwe izinto ezinikeza kumiswa okuyinhloko kanye nezici ngokobulili yesibili.
5. Ukulungiswa umzimba nokushintsha kwendawo ezungezile. Isibonelo salokhu iqembu ketshezi catecholamine ezifana epinephrine. Abakwazi kuthinte kwenhliziyo, ukujuluka, bronchiectasis.
6. Umthelela isimo psycho-ngokomzwelo nesimilo izici umsebenzi womuntu. Ngokwesibonelo, ama-hormone glucocorticoid kungabangela umuntu sengeneme, kodwa isivuno sisiningi kuholela ukucindezeleka okunzima.
