Ama-Acids, ama-Enzyme, i-Mucus, nokuningi
Uma nje ubeka ukudla emlonyeni wakho isisu sakho siqala ukukhulula ama-gastric juices. Le ingxube yeketshezi izosiza ukuhlakaza ukudla uma ifika esiswini kanti inqubo yokugaya iqala.
Ziyini lezi amajusi azenziwe futhi zigcina kanjani umzimba wakho uphilile? Ake sithathe uhambo lwesigaba sokuqala sesistimu yakho yokugaya bese uthola.
Indlela Umzimba Wakho Okhiqiza Ama-Gastric Juice
Ukudla kwakho ukuhlafuna nokugwinya kubizwa ngokuthi i-bolus.
Ixuba namajusi esiswini abanjwe izigcawu ezikhethekile ezitholakala emgodini wesisu sakho. Zihlanganisa izilonda zenhliziyo ezingxenyeni eziphezulu zesisu, izigulane ze-oxyntic emzimbeni omkhulu wesisu, kanye nezinhlayiya ze-pyloric ezincane noma ezingxenyeni eziphansi kakhulu zesisu.
I-albhamu ngayinye iqukethe amaseli enza izinsimbi ezithile ezihlangene ezibizwa ngokuthi ama-gastric juices. Amangqamuzana emisipha akhiphe i-bicarbonate futhi ama-mucous, ama-parietal amaseli ahlanganisa i-hydrochloric acid, amangqamuzana amancane ahlanganisa i-pepsinogen, namaseli e-enteroendocrine ahlanganisa ama-hormone ahlukahlukene. Nokho, akuzona zonke izigulane zesisu eziqukethe zonke izinhlobo zeseli.
Ukuphulukisa amaJuni we-Gastric
Ijusi le-gastric lakhiwa ngamanzi, i-electrolytes, i-hydrochloric acid, ama-enzyme, i-mucus, nesici sangaphakathi.
I-Hydrochloric acid i-acid enamandla eyakhiwe ngamaseli e-parietal, futhi ihlisa i-pH yesisu sakho nxazonke 2. I-Hydrochloric acid iguqula i-pepsinogen ibe yi-pepsin iphinde iphule izakhi ezihlukahlukene ngaphandle kokudla okudlayo.
Ibulala amabhaktheriya ahambisana nokudla kwakho.
I-Pepsinogen ibanjwe ngamaseli asemqoka , futhi lapho ikhona khona i-hydrochloric acid, iguqulwa ibe yi-pepsin. I-Pepsin ihlukanisa izakhiwo zamaprotheni eziphakeme nakweyesibili ukwenzela ukuthi kube lula ukuba ama-enzyme yokugaya emathunjini amancane asebenze kamuva.
I-gastric lipase enye enye ye- enzyme yokugaya ezenziwe ngamaseli asemqoka. Kuyasiza ukwephula amafutha amancane naphakathi.
U-Amylase utholakala nasemanzini esiswini, kodwa akenzi ngesisu. Le enzyme ivela emathunjini futhi ihamba kanye ne-bolus esiswini. U-Amylase uphula ama-carbohydrate, kodwa awunaso isikhathi esiningi sokusebenza esiswini ngoba i-acidity iyayimisa. Kodwa lokho kulungile, intumbu yakho encane yenza i-amylase ngaphezulu kamuva.
I-intrinsic factor is secreted by cell cells futhi kuyadingeka ukuba umzimba wakho uthathe i-vitamin B-12. Lokhu kubalulekile ekusebenzeni kwesistimu enomsoco kanye nokukhiqizwa kwamangqamuzana egazi.
Okokugcina, ama-juice esiswini asinamanzi kanye ne-mucus. I-mucus ibanjwe ngamangqamu entamo futhi isiza ukugqoka futhi ivikele isilonda sakho esiswini kusuka kumvelo we-asidi.
Konke kusebenza ndawonye
Imisipha yakho yesisu ikhiphe futhi ixube ukuxuba i-bolus nazo zonke lezi juzi zokugaya. Ingxube yeketshezi ibizwa ngokuthi i-chyme. Uma sesilungile, isisu sakho sigxuma i-chyme emathunjini amancane lapho ukugaya kuqhubeka nokuqhathaniswa kwalezo zakhi zomzimba ezibaluleke kakhulu.
