Qhov siab tshaj plaws uas lub plab kua qaub mus txog hauv plab yog 160mw hauv Canaliculi. Qhov no yog hais txog 3 lab lub sij hawm ntawd ntawm arterial ntshav, tab sis yuav luag raws nraim isotonic nrog rau lwm cov kua hauv lub cev. Qhov qis tshaj pH ntawm zais cia kua qaub yog 0.8, tab sis kua qaub yog diluted hauv plab lumen ua a pH ntawm 1 thiab 3.
Ua kom pom qhov no, lub plab acid muaj zog npaum li cas?
0 yog acidic tshaj plaws, 7 yog nruab nrab, thiab 14 yog acidic tsawg tshaj plaws. PH ntawm plab acid feem ntau yog hom twg los ntawm 1 txog 3. Thaum nws muaj zog tshaj, pH ntawm plab acid cia li hauv qab ntawm lub roj teeb kua qaub ! Tias yog vim li cas nws muaj peev xwm noj tau los ntawm cov zaub mov hauv koj plab sai sai zoo nkauj
Ib yam nkaus, koj lub plab kua qaub tuaj yeem yaj tau dab tsi? 13 Koj lub plab thawj digestive kua txiv, hydrochloric kua qaub , tuaj yeem yaj hlau, tab sis cov khoom ua si yas uas nqes mus rau lub hatch yuav tawm mus rau lwm qhov kawg zoo li tshiab.
Tsis tas li kom paub, yog lub plab kua qaub yog kua qaub?
Cov plab muaj hydrochloric acid, muaj zog acid uas pab zom cov zaub mov thiab tiv thaiv cov kab mob xws li kab mob. Lub hauv ob sab phlu plab tshwj xeeb tau yoog los tiv thaiv nws los ntawm cov muaj zog kua qaub , tab sis txoj hlab pas tsis tiv thaiv.
Yuav ua li cas txaus ntshai yog mob plab?
Yog tsis kho, GERD tuaj yeem ua rau muaj teeb meem loj hauv lub sijhawm ntev, suav nrog kev pheej hmoo pheej hmoo ntawm mob qog noj ntshav. Raug raug rau plab acid tuaj yeem ua rau txoj hlab pas puas, ua rau: Txoj hlab pas: cov hlab ntawm txoj hlab pas tau ua paug, ua rau khaus, los ntshav, thiab ua rau mob hauv qee kis.

Vim li cas cov kua qaub thiab enzymes hauv plab tsis nquag zom plab hauv plab?
STOMACH tsis zom nws tus kheej vim tias nws tau hlua nrog cov epithial cells, uas tsim cov hnoos qeev. Qhov no ua ib qho teeb meem ntawm sab hauv ntawm lub plab thiab cov ntsiab lus. Enzymes, uas ua ib feem ntawm cov kua txiv zom zaub mov kuj tseem zais los ntawm lub plab phab ntsa, los ntawm cov qog uas tsis muaj qhov thaiv qhov ncauj
Cov kua qaub plab thiab cov zom zaub mov muaj txiaj ntsig zoo li cas rau cov qauv protein?
Lub plab acid tsis zom cov protein. Qhov tseeb, nws ua kom muaj enzyme hu ua pepsinogen uas tom qab ntawd dhau los ua pepsin uas zais los ntawm lub plab phab ntsa. Qhov enzyme no tsuas yog ua haujlwm nyob hauv thaj tsam pH ntawm 3.0 txog 5.0 thiab xav tau cov kua qaub los tswj hwm pH ntawd
Cov kua qaub twg tua cov kab mob hauv lub plab?
Koj lub plab hauv plab tseem zais cov kua qaub hydrochloric, uas tsim cov xwm txheej zoo tshaj plaws rau cov protein zom zom cov enzymes kom ua haujlwm. Lub zog hydrochloric acid tua cov kab mob, tiv thaiv koj lub cev los ntawm cov kab mob phem uas tuaj yeem nkag mus rau hauv koj lub cev hauv cov zaub mov
Dab tsi tiv thaiv lub plab hauv plab los ntawm cov kua qaub?
Hauv plab ntau yam txheej txheem tiv thaiv mucosal tiv thaiv lub plab tawm tsam hydrochloric acid thiab cov tshuaj lom. Kev tiv thaiv ua ntej-epithelial yog ua los ntawm cov mucus-bicarbonate teeb meem. Mucus thiab bicarbonate, secreted los ntawm mucus hlwb, tsim pH gradient tswj lub epithelial cell nto nyob ze nruab nrab pH
Dab tsi yog qhov kev txiav txim ntawm cov kua qaub rau cov enzyme hauv qaub ncaug?
Carbohydrates tau tawg thoob plaws hauv lub plab. Salivary amylase yog ib qho enzyme hauv lub qhov ncauj uas pib zom cov carbohydrates hauv daim ntawv ntawm cov hmoov txhuv nplej los ntawm kev cuam tshuam cov hydrolysis ntawm polysaccharides rau hauv disaccharides. Txawm li cas los xij, qhov chaw tseem ceeb rau kev zom zaub mov carbohydrate yog cov hnyuv me
