Kapamba umabala ena mahomoni?

Kapamba tiri m'magulu awiri: exocrine agwilitse 98% ndi khansa pancreatic - mu mawonekedwe a inclusions zing'onozing'ono padziko lonse.

dipatimenti Endocrine amachititsa katulutsidwe wa chapamimba madzi ndi kulamulira njira zikuchitika mu duodenum ndi m'mimba madzimadzi michere osabwereranso kumeneko mpaka zitanyowetsa.

The endocrine gawo ndi udindo kupanga timadzi.

ntchito mahomoni

Kapamba umabala mahomoni awiri - insulin ndi glucagon ndi. The ndondomeko atapanga glucagon nawo maselo Alpha, ndi insulin zimakhudzidwa yopanga beta-maselo. Komanso mitundu awiriwa maselo muli chitsulo ndi ankadziwana maselo kwambiri imene chakudya somatostatin.

ndi mahomoni opangidwa ndi kapamba Kodi

insulin anthu ogaŵikana mitundu iwiri: woyambira ndi chidwi.

Woyambira mtundu amakhala mu wolowera magazi popanda kufunika. Chitsanzo cha kudzipatula amenewa kupanga insulin, pamene chakudya si kuyenda mu thupi, i.e. pa chopanda kanthu m'mimba.

Mfundo magazi shuga - osapitirira 5.5 mmol / l, pamene mlingo wa insulin kuti 69 mmol / L.

Chifukwa cholephera mtundu wotchedwa malonjezo akuwuka kwa mowa chakudya ndi chakudya amino zidulo ndi shuga m'magazi. Secretory ntchito mahomoni awa amatchedwa stimulyativnomu zotsatira za mankhwala amene wapangidwa sulfonylurea a.

insulin kukondoweza amapezeka mu mbali ziwiri:

• Short - timadzi izi kufika magazi.
• Wosakwiya - izo synthesizing timadzi.

Pambali, pali komanso umatulutsa zosiyanasiyana zinthu ofanana nawo njira m'mimba. mndandanda zimasonyeza zimene michere umatulutsa kapamba:

• Zinthu kanthu pa mapuloteni - ndi trypsin, chymotrypsin, carboxypeptidase A ndi B, elastase, ribonuclease.
• Zinthu angathe chosinkhasinkha chakudya: amylase, invertase, maltose, lactose.
• Zinthu wopalamula kuphwanyaphwanya mafuta. Iwo cholinesterase ndi lipase.

Ngati kumene kapamba sangabereke michere aliyense alipo, kapena kulephera amapezeka fermentopathy kugwirizana ndi matenda concomitant.

Udindo wa mahomoni

Udindo wa kapamba mu ulimi wa insulin ndi glucagon ndi kusintha zimam'patsa ndi zamadzimadzi kagayidwe, komanso chikoka pa kusokonekera kwa shuga kwa madzi a m'magazi magazi mu minofu.

Ntchito yake yaikulu ili kuti lithe lipokaina lomwe lili ntchito kutsekereza ndipo alibe maselo chiwindi.

Pankhani ya ochepa kwambiri pamene kapamba umabala osakwanira chiwerengero cha mankhwala amenewa, mahomoni kulephera kumayamba njira machitidwe a chamoyo, chimene amayamba chifukwa osati yotengedwa, koma malformations kobadwa nako.

Pamene kapamba umabala osakwanira insulin timadzi kuchuluka amapezeka matenda - shuga. Mu kwambiri glucagon owonjezera kumawonjezera insulin zili ndi kuchepetsedwa shuga ndende ya maselo, womwe kumaonjezera kuchuluka kwa Epinephrine. Ndiye pali hypoglycemia - kuchepa mphamvu ya maselo chiwindi kwa processing a shuga.

Popeza kapena kwambiri kuchepa kwa somatostatin kumabweretsa kuyan'anila za njira zosiyanasiyana za chamoyo ntchito kuphwanya bwino njira kagayidwe kachakudya.

Kodi insulin

Zotani mahomoni opangidwa ndi kapamba, anamanga zolimbitsa thupi kagayidwe mafuta m'thupi.

Pamaso mapangidwe insulin, pamene kaphatikizidwe zake beta-maselo secrete chinthu proinsulin. Palokha si timadzi. The ndondomeko kutembenuka kumachitika pansi zochita za Golgi ake komanso kupezeka kwa mankhwala wapadera enzymatic. Pambuyo pa ndondomeko ya kusintha ake mu dongosolo selo izo adzamvetsera insulin. Ndiye pali kukonzanso mayamwidwe kumbuyo, kumene iye anali granulated natuma yosungirako, kumene adzakhala yotsatira mwadzidzidzi pamene kugonjera ndi chizindikiro thupi.

dongosolo kumayambika pamene mlingo wa shuga m'magazi pamene maselo anamasulidwa insulin kusungidwa kwa neutralization ake ndi processing yoyenera glycogen wowonjezera ndende zake maselo chiwindi mu mnofu minofu, monga katundu wa mphamvu thupi lonse. Chifukwa zotsatira za insulin, misinkhu shuga madzi akhoza lotengeka msanga kubwerera mwakale.

Pozindikiritsa magawo a wokhutira mkulu magazi ndi kuonedwa ngati mbendera kuti thupi chimatsutsana zoipa kuchuluka kutulutsidwa kwa timadzi chimango kuti kulephera kwa maselo udindo zimam'patsa kagayidwe, kuzindikira ndi kuthetsa vuto limeneli. Chifukwa cha zimenezi, iwo amayamba kukhala matenda otchedwa shuga. Zotsatira za chakuti chakudya ndi ingested, si kukonzedwa ndipo sangathe m'mimba, nchifukwa chake MAGAZI kusonyeza mpweya wambiri wa shuga m'magazi.

Zizindikiro za matenda amenewa popanda kuwononga kwambiri ludzu kafukufuku ndi kuti limodzi ndi luso shuga kuyamwa chinyontho. Choncho, osati zopanda magazi, izo zimayambitsa kuchepa madzi m'thupi.

Kodi Mzimuyo amasulidwe insulin

Kapamba umabala michere ndi mahomoni, ndithu mochenjera kumverera kusintha pang'ono mu shuga magazi. Chifukwa ichi, ndipo akukamba zizindikiro thupi kuyamba mapangidwe kuchuluka tochepa insulin, kapena pofuna kuchepetsa ndi kutumiza ndikusunga.

Mu chochitika cha matenda a shuga, ndi Zilumba za zopangitsa za endocrine zimasintha ndi chisokonezo ntchito anachita. Choncho, matenda ashuga ndi mndandanda wa katundu amene contraindicated ku ntchito chifukwa okhutira mkulu wa shuga, thupi silingathe kupirira. Iwo mitanda ndi maswiti, uchi, zakudya zimam'patsa ndi shuga mu maonekedwe ake angwiro. An overabundance wa shuga m'magazi kumabweretsa kutopa kwambiri maselo beta udindo kaphatikizidwe insulin, ndipo kungachititse kuti imfa mtheradi.

glucagon

Kapamba umabala glucagon maselo a Alpha. mucosa matumbo interaglyukogon kutulutsa timadzi, amenenso ndi synergist zikuwonjezereka masiku ano. Izi timadzi pancreatic udindo otaya ulamuliro lipolysis ndi mathamangidwe ake, komanso ali ndi zotsatira mwachindunji glycogenolysis kwa chiwindi.

Waukulu zofunika ntchito ya kapamba mu thupi kusankha mahomoni osiyanasiyana omwe amalimbikitsa chimbudzi ndi mayamwidwe izo.
