Ib tus tib neeg laus plab yuav tso tawm txog 1.5 litres ntawm plab hnyuv txhua hnub. Cov kua qaub zais zis tshwm sim hauv ob peb theem. Chloride thiab hydrogen ions tau muab cais cais los ntawm cytoplasm ntawm cov hlwb parietal thiab sib xyaw hauv cov kwj deg.
Tib neeg tseem nug, muaj zog npaum li cas cov kua qaub hauv koj lub plab?
0 yog acidic tshaj, 7 yog nruab nrab, thiab 14 yog acidic tsawg. Cov pH ntawm plab acid feem ntau yog hom twg los ntawm 1 txog 3. Thaum nws muaj zog tshaj, pH ntawm plab acid hauv qab no xwb ntawm roj teeb kua qaub ! Tias yog vim li cas nws thiaj tuaj yeem noj los ntawm cov zaub mov hauv koj lub plab sai sai zoo nkauj
Qhov thib ob, ua li cas cov kua qaub nyob hauv koj lub plab? Cov leeg txav cov ntsiab lus ntawm lub plab nyob ib puag ncig muaj zog heev uas cov khoom sib zog ntawm cov khoom noj tau zom thiab hauv av, thiab sib xyaw ua ke rau hauv cov zaub mov. Cov tshuaj hydrochloric acid nyob rau hauv lub plab kua txiv zom cov zaub mov thiab cov zom zaub mov zom zom cov protein. Cov kua qaub plab kua txiv kuj tua cov kab mob.
Yog li, 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 cov 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.
Puas muaj sulfuric acid nyob hauv plab?
Sulfuric kua qaub tsim cov coagulation necrosis ntawm tus txiav plab mucosa thiab submucosa, thiab cov txheej txheem tuaj yeem koom nrog tag nrho cov tuab ntawm plab phab ntsa, nrog tom qab mob plab thiab fibrosis.

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
Muaj pes tsawg txheej ntawm cov leeg nqaij hauv plab hauv tus menyuam hauv plab?
Nws txuas ntxiv tom qab mus rau pectoralis loj, pib los ntawm lub sternum thiab tso rau ze ze ntawm qhov kawg ntawm lub humerus, tseem ua rau lub hauv pliaj. Muaj peb txheej txheej ntawm cov leeg uas ua rau sab phab ntsa ntawm lub plab, thiab cov leeg nqaij thib plaub ua rau sab nrauv ntawm phab ntsa
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
