Basic ndlala secretion ingxubevange

Xa abantu cell prostate zangaphakathi, zangaphandle mixed secretion ndlala. Ngu amadlala exocrine ekunokuthiwa, umzekelo, kwamadlala amathe, ekuthi kwezo nto kuphume imfihlo yabo (kulo mzekelo - amathe), nto leyo imveliso ngokusebenzisa imibhobho ezizodwa. Ke kwamadlala yonyango (ezidalwe) ukuba bavelise izinto ezithile - hormone - azikhutshwa ngqo kwi egazini.

Ndlala secretion mixed - ezi izinto ezakhiwe ngazo cell ukuba zombini iihomoni kunye nezinye izinto (enzyme, ukutya, njl njl). Ezi ziquka injeke kunye kwamadlala ngesondo, kunye nezintso, amadlala esiswini kunye duodenum.

Le injeke - a netuwa ezinkulu nobubovu, ugalelwe, nto leyo imi emva isisu. Siqulathe intloko, nomsila kunye nomzimba.

Njengoko usazi, oku amalungu yinxalenye yenkqubo yokwetyisa. imibhobho ndlala vula kungena kulo duodenum, apho, yaye yakhupha babizwa ngokuba incindi pancreatic. Enzyme equlethwe yencindi yewayini; banoxanduva yokuwa amafutha, iikhabhohayidrethi kunye neeproteni.

Umzekelo, amylase pancreatic unoxanduva cleavage of dextrin kunye nezinye carbohydrate. Amafutha aqhekeke abe kwiiyunithi monomeric phantsi kwempembelelo lipase phantsi. Ukongezelela, i injeke ukhupha chymotrypsinogen kunye trypsinogen - enzyme ukuba cleavage of iikhompawundi protein. Enza ezi zinto sele kwi sayo emathunjini.

nepancreas ngasese ikwaqulathe unako yesoda. Owona msebenzi wabo - na neutralization of chyme asidi, leyo eshenxela emathunjini ukusuka esiswini.

i nemisele of Langerhans - Ke ukuba secretion yangaphakathi, lo msebenzi iindawo ezithile prostate olwenziwe. Zininzi iintlobo eyodwa iiseli:

• Beta - iiseli - banoxanduva Yindibanisela insulin;
• Alpha - iiseli - ukuba kuhlelwe hormone glucagon;
• Delta - izisele - banoxanduva nemveliso somatostatin;

Insulin glucagon - hormone onoxanduva carbohydrate ukutya kunye, xa glucose ethile. ukunyuka kweqondo insulin Bephenjelelwa of ukuyilwa glycogen, nto leyo kamva efakwe esibindini. Glucagon, ke, izenzo njenge ochasene - kukhuthaza iinkqubo sokonakalisa glycogen kunye protini. Ke ukuba somatostatin, iyeza uyakwazi isantya umsebenzi zombini glucagon kunye insulin.

ndlala zangasese - it kwakhona indlala netuwa kuxutywe. Ezi ziquka zamaqanda, bekuza kunye nokukhula, nokwanda kunye nokukhululwa amaqanda. Kodwa ke umsebenzi zamaqanda akukho nje malunga nokuzala.

Le hormone eziphambili female - estrogen na (ukuba kuhlelwe kwi zoboya) kunye dlala (eveliswe luteum corpus). Estrogen - iqela kwezinto phantsi kwempembelelo apho uphuhliso iimpawu zesini ababhinqileyo kunye nokukhula nokwanda nobubovu mammary, ukukhula isibeleko, lobufazi, tubes kunye zamaqanda. Enkosi kubo, ukukhula unwele olwenziwe uhlobo ababhinqileyo. Ukongeza, ukuba estrogen ukukhuthaza imveliso amanqatha kunye nokusasazwa kwawo wonke umzimba.

Hormone yenziweyo luteum corpus emva kokukhutshwa iqanda ukusuka follicle. Owona msebenzi wayo - ekulungiseleleni isibeleko ngenxa umzila we umbungu, kunye nolawulo phezu eliqhelekileyo yokukhulelwa. Xa ethwele umntwana phantsi kwempembelelo dlala elinganeno iinkqubo ovulation.

Amadoda ndlala sex - kuba indlala secretion engumxube, athi abenoxanduva ekuveliseni iiseli isini kunye iihomoni. Xa ukuyilwa amasende, ukukhula, uphuhliso kunye nokuvuthwa madlozi.

hormone sex Amadoda - androgens kuyo, apho eyaziwa engcono testosterone. Phantsi kweempembelelo weli lwenziwa uphuhliso neempawu zesini eziziiprayimari neziziisekondari - ukukhula eveze zangaphandle nezangaphakathi, ngelizwi eliphantsi, bole liphuhlise musculature, noboya obuninzi emzimbeni, njl

Njengoko kubonisiwe, indlala secretion elingumxube zibaluleke kakhulu emzimbeni womntu kunye nokulondoloza homeostasis.
