Amadlala Ezingokuqandusela - Supplier wakho iihomoni zendalo

namadlala Ezingokuqandusela. Yintoni esinokuyifunda kwabo isihloko? Okokuqala, zibizwa namadlala, ekubeni kwenziwa kuphela iiseli ezithile secretory yaye ifom kwezakhiwo glandular. Okwesibini, ibinzana elithi "secretion lwangaphakathi," utsho ukuba ukwabiwa kwazo luqinisekisa musa kucanda misele excretory. Ezi iindlela akukho namadlala. Banikela izinto zabo ngqo iimpahla nkovu okanye yegazi balwenza le ndlala. Okwesithathu, injongo yale maqumrhu - umsebenzi secretory. Imfihlelo (okanye, ngamanye amazwi, netuwa) amadlala data le yincindi ethile.

amadlala Ezingokuqandusela banikwa hormone umzimba kwabantu imvelo ezahlukeneyo. Abanye kuquka iiprotheni, ngoxa abanye - kwimveliso zabo kungonakali, ezinye zivela amafutha ezifana cholesterol ngeendlela ezahlukahlukeneyo. Noko ke, kungakhathaliseki uhlobo emzimbeni, bonke baya kuba injongo ethile, kwaye loo nto yenza ukuba lubalasele iqela eyahlukileyo kwezinto.

Ukuze into secreted yi iiseli yeziko, ogama hormone njengoko ilungu apho uvelisa, iye yabekwa kuluhlu kudidi 'yesinye zabantu ", kufuneka ukuba le mihlaba ilandelayo:

1. hormone ekhuthele nokomzimba. Alubonakalisa lo mhlaba kukuba utshintsho incinane kwicala ukwandisa okanye ukunciphisa isixa kweziyobisi emzimbeni ebangela waso. Ngenxa yesi sizathu, oko kuyingozi ukuthatha hormone ngeedosi engalawulekiyo. Kuba eziphilayo nganye, idosi kufuneka ibe ngabanye emva kuphando ezinzulu.

2. hormone uyakhetha kakhulu. Ngamnye kubo isebenza kuphela amalungu athile kwaye akufuneki angqamane nemisebenzi nezinye iinkqubo.

3. Xa ubomi hormone onokufaniswa mabhabhathane yosuku olunye. Ziye ke wavelisa ngokukhawuleza benze umsebenzi wabo, koko baphuke phantsi kwaye salawo aphumayo. Oku kufuneka iqwalaselwe xa uthatha iimvavanyo. Xa ngamaxesha ahlukeneyo enyakeni, ngenyanga, kwaye nkqu ixesha losuku iya kuba isixa ezahlukeneyo hormone emzimbeni womntu. Ezinye zazo ziveliswa kuphela xa ubudala buthile, okanye imeko umzimba.

Ekubeni wafunda iimpawu ehlele (iimfihlelo) amalungu oluntu ezahlukeneyo, izazinzulu ziye zafumanisa ukuba kuphela ezinye iiseli hormone. Ezi seli babebizwa secretory (olukwaziyo ukuvelisa iihomoni), kwaye amalungu equlathe kubo, ziye lineminyaka kwinkqubo eyahlukileyo. Ngoko ke inzululwazi zibandakanya kwamadlala yonyango. Ukuza kuthi ga ngoku, bafunda kakuhle kuphela abathile kubo, ezizezi ingqondo yebhinqa, gonads, adrenal, lengqula ndlala.

Ubume unamadlala ezidalwe kunzima kakhulu ukufunda, njengoko bonke ise nzulu emzimbeni, wazigquma ngamanye amaqumrhu :. luKakayi, izintso, isisu, njl Ukongeza, ubungakanani prostate iphantsi kakhulu, nto leyo ebangela kubenzima lezifundo zabo. Lo mthombo uphambili ulwazi malunga indlala ethile le yincindi kuba uvelisa. Imisebenzi ye hormone bafunda ekuhlalutyeni igazi, kunye negalelo na emzimbeni wonke.

Kwakhona umdla kukuba uluhlu lwe kwamadlala ezidalwe ukuza kuthi ga ngoku ayikho obupheleleyo. Science namayeza abayi bemi ngxi. ubugcisa ezintsha kwenza kube lula ukufunda ngcono eneenkcukacha ngakumbi ubume ancedisana iiseli sele imizimba eziqhelekileyo, ukuchonga yonke imisebenzi emitsha ukuba enze.

Kwiminyaka yakutshanje, oko kwazeka ukuba amanye amalungu kumafa yabo, kwakunye kwamadlala yonyango, kuba imali encinane iiseli secretory esikwaziyo ukuvelisa iziyobisi, ngenyathelo ezinxulumene iihomoni. Umzekelo, kwafunyaniswa ukuba duodenum iphuhlisa secretin, ethi ichaphazele injeke. Nezintso nokuwiswe yabo ukutshintsha uxinzelelo lwegazi. Le spleen inikeza into okuvuselela ukuba umongo ukhuphe iiseli ezibomvu. Kusenokwenzeka ukuba ukufunda ngakumbi ezi seli ziya ukwandisa kakhulu kuluhlu izidumbu ukuba enze umsebenzi ezidalwe ebantwini.
