Le injeke ivelisa ezinye hormone?

Le injeke yenziwa ngamaqela amabini: exocrine elifumileyo 98% kunye nomhlaza pancreatic - ngokohlobo inclusions ezincinane phezu kumphezulu wayo yonke.

isebe Ezingokuqandusela elijongene secretion iinkqubo ijusi kunye nolawulo esiswini ezenzeka kulwelo enzyme zigcwele duodenum esiswini.

I yonyango okuyingxenye unoxanduva imveliso hormone.

umsebenzi hormone

Le injeke ivelisa iihomoni ezimbini - insulin kunye glucagon na. Inkqubo yokwenza glucagon ababandakanyekayo iiseli alpha, kunye insulin bazibandakanye ekuveliseni beta-iiseli. Ukongeza kwezi ndidi zimbini eziseleni iqulethe iiseli zentsimbi kunye ogudle ngaphezulu ukuvelisa somatostatin.

Yintoni hormone eziveliswa injeke

insulin yabantu zohlulwa ngokwendidi ezimbini: carcinomas kwavusa.

uhlobo carcinoma ungachazwa okungena igazi ngaphandle kwesidingo. Umzekelo bohlukaniswe enjalo ingaba imveliso insulin, xa ukutya akuthethi ingena emzimbeni, ngamanye ungatyanga.

Standards glucose igazi - hayi ngaphezulu kwe 5.5 mmol / l, lo gama kwinqanaba insulin ukuba 69 mmol / L.

Zaphenjelelwa uhlobo ekuthiwa izithembiso ezivela ukuselwa ukutya kunye nonikezelo acid kunye iswekile egazini. umsebenzi Secretory ezi hormone ekuthethwe stimulyativnomu iziphumo iziyobisi iqanjwa a sulfonylurea.

insulin nqgo Kwenzeka ngezigaba ezibini:

• Mfutshane - le hormone ukufikelela igazi.
• Slow - loo nto synthesizing hormone.

Ngaphandle kwabo, kukho kwakhona yaveliswa ezahlukeneyo izinto ezinxulumene inxaxheba kwiinkqubo yokwetyisa. Olu luhlu lubonisa into enqanda eveliswe injeke:

• Substances abasebenza kwi iiproteni - na trypsin, chymotrypsin, carboxypeptidase A no B, elastase, ribonuclease.
• Substances ekwaziyo carbohydrate ekwetyiseni: amylase, invertase, maltose, lactose.
• Substances unoxanduva ukwaphula phantsi amafutha. It cholinesterase kunye lipase.

Kwimeko apho injeke ayisebenzi naziphi enzayim langoku, okanye ukusilela kwenzeka fermentopathy ezinxulumene nesifo ezihamba.

Indima hormone

Indima zepancreas kwi kwimveliso kwencindi kunye glucagon kukuba ukunyenyisa carbohydrate kunye lipid ukutya, kwakunye namava nokunikezelwa glucose ukusuka igazi plasma kungena kwithishyu.

Owona msebenzi walo ukuba nokulungelelanisa lipokaina leyo ibizwa umsebenzi bavimba ukonakala kweeseli zesibindi.

Kwimeko yokunqongophala xa injeke ivelise inani elingonelanga iikhompawundi ezifana, ukusilela kwamadlala uqala iinkqubo ukusebenza ephilayo, nto leyo ebangele ngenxa nje zifumaneka kuphela, kodwa malformations bekhubazekile.

Xa injeke ivelise zaneleyo imali insulin hormone kwenzeka izifo - seswekile. Xa glucagon excess kakhulu kwandisa umxholo insulin kwaye kunciphise yeswekile yoxinaniso leeseli, nto leyo kwandisa umthamo epinephrine. Ngoko kukho hypoglycemia - ukuhla isakhono iiseli zesibindi ukuya inkqubo glucose.

Ukungafakwa okanye kakhulu ukunqongophala somatostatin ikhokelela ukunyhashwa iinkqubo ezahlukeneyo yomsebenzi eziphilayo waphula umthetho eseleyo kweenkqubo metabolic.

Njani insulin

Koluphi uhlobo hormone eziveliswa injeke, wakha umthambo ngamanqatha yokucolwa wonke umzimba.

Ngaphambi kokuba kwakhiwe insulin, ngelixa kuyondelelaniswe yayo beta-cell a proinsulin kweziyobisi. Ngokwalo ukuba akukho hormone. Inkqubo yokuguqula ithatha indawo phantsi amanyathelo yodederhu yayo Golgi kunye nokufumaneka iikhompawundi ezizodwa enzymatic. Emva kokuba inkqubo yotshintsho lwayo isakhiwo iseli oko kuya kuba insulin. Kukho kwakhona ukufunxeka emva kwakhe, apho granulated wathumela zogcino, apho uya kuthi kwakhona kwi imeko kaxakeka xa uthumela imiyalezo umzimba.

Le nkqubo izakufunyanwa xa umgangatho iswekile egazini xa iiseli wakhululwa insulin agcinwe ukuba neutralization kunye nokusebenza efanelekileyo glycogen, ukwandisa eyavela iiseli sesibindi inwebu kwezihlunu, njengoko umxhobisi amandla umzimba wonke. Ngenxa iimpembelelo insulin, amanqanaba glucose iplasma zisenokuba ziqhutywa ngokukhawuleza emva esiqhelweni.

Xa ekuboneni parameters umxholo wayo eziphakamileyo igazi ukuba ithathwe isibonisi umzimba, umelene ukukhululwa kakubi kakhulu ngayo loo hormone enebana ukungakwazi receptors anoxanduva carbohydrate ukutya, ukuqaphela ukuphelisa le ngozi. Ngenxa yoko, uqala ukuphuhlisa nesifo ekuthiwa seswekile. Iziphumo yokuba wekhabohayidreyiti ongena ebantwaneni, azisetyenzwa kwaye azinakwetyiswa, nto leyo esisizathu sokuba iimvavanyo kwegazi zibonisa amazinga aphezulu eswekile yegazi.

Iimpawu zezi zifo ngaphandle ngokubeka zePCR unxano kakhulu kukuba ezinxulumene nako glucose ukuba ukufunxa ukufuma. Ngoko ke, ukuba bangabi egazini, ibangela emzimbeni.

Yintoni egqibayo ukukhululwa insulin

Le injeke ivelisa enzyme iihomoni, kakhulu Babaqhathanisele uziva utshintsho incinane iswekile egazini. Ngenxa oku, yaye Uyamhlangula maza ukuze umzimba ukuqala ukuyilwa eyandileyo mali ka-insulin, okanye imfuneko ukunciphisa kwaye uthumele kulo myezo.

Kwimeko seswekile, le nemisele kwamadlala ezidalwe enziwe iinguqu yokuphazamiseka imisebenzi eyenziwa. Ngoko ke, abanesifo seswekile kufuneka uluhlu iimveliso contraindicated ukulisebenzisa ngenxa isiqulatho eliphezulu iswekile, apho umzimba ungakwazi ukumelana. Ngoko ehla kunye neelekese, nobusi, ukutya carbohydrate, kunye neswekile ekwimo yayo enyulu. An ngokugqithiseleyo eswekile yegazi ikhokelela ukudinwa ngokugqithiseleyo weeseli beta onoxanduva insulin amagama yaye kubangele ukuba afe ngokupheleleyo.

glucagon

Le injeke uvelisa glucagon iiseli alpha. isifo isisu interaglyukogon ukuveza hormone, nto leyo nayo iadrenaline synergist. Le hormone pancreatic onoxanduva lipolysis ulawulo flow kunye uqina yalo, kananjalo ibe nefuthe ngqo kwi glycogenolysis hepatic.

Umsebenzi ephambili ebalulekileyo zepancreas emzimbeni womntu ukhetho iihomoni ezahlukeneyo ukukhuthaza yokwetyiswa nokufunxwa kuyo.
