Parietal cells Parietal cells Parietal cells (tseem hu ua oxyntic cells) yog cov hlwb epithelial hauv plabuas zais cov hydrochloric acid (HCl) thiab qhov tseem ceeb hauv lub cev. Cov hlwb no nyob rau hauv cov qog nqaij hlav hauv plab uas pom nyob rau hauv cov kab mob ntawm lub plab thiab lub cev ntawm lub plab. https://en.wikipedia.org › wiki › Parietal_cell

tsim HCl los ntawm kev zais cov hydrogen thiab chloride ions. Thaum pepsinogen pepsinogen keeb kwm: Serum pepsinogen assay ( sPGA) combining concentration ntawm pepsinogen I (PG I), thiab qhov piv ntawm PG I / II yog cov biomarker uas tsis muaj kev cuam tshuam rau kev kwv yees atrophic gastritis (CAG).) thiab neoplasms cuam tshuam qhov mucosal secretory xwm txheej. https://pubmed.ncbi.nlm.nih.gov › …

thiab hydrochloric acid nyob ua ke hauv cov kua txiv hmab txiv ntoo gastric kua txiv Koj cov qog ua kua qaub ua rau qaub ncaug, kua txiv digestive, uas moistens zaub mov kom nws txav tau yooj yim dua los ntawm txoj hlab pas rau hauv koj lub plab.. Cov qaub ncaug kuj muaj enzyme uas pib zom cov hmoov txhuv nplej siab hauv koj cov zaub mov. https://www.niddk.nih.gov › digestive-system-how-it-works

pepsin siv nws daim ntawv nquag.
HCl los ntawm plab nyob qhov twg?
HCl yog tsim los ntawm cov parietal hlwb ntawm lub plab . Pib nrog, dej (H2O) thiabcarbon dioxide (CO2) ua ke hauv parietal cell cytoplasm los tsim carbonic acid (H2CO3), uas yog catalysed los ntawm carbonic anhydrase.
HCl zais cia nyob qhov twg?
plab hnyuv plab thiab nqus
Hydrochloric acid yog cov khoom tseem ceeb ntawm cov kua txiv hmab txiv ntoo thiab tso tawm los ntawmcov parietal hlwb ntawm lub plab mucosa nyob rau hauv fundus thiab corpus. Hauv cov neeg laus noj qab haus huv, intragastric pH nyob nruab nrab ntawm 1.5 thiab 2.5 hauv lub xeev yoo mov.
HCl hauv plab yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm HCL yog txhawm rau muab H + tsim nyog rau kev ua kom cov pepsinogen rau hauv pepsin. Kwv yees li 2 litres ntawm HCL tau tso tawm txhua hnub rau hauv peb lub plab. Nws kuj ua haujlwm rau lub hom phiaj ntawm kev tiv thaiv los ntawm kev tua qee cov kab mob los ntawm ib puag ncig acidic siab.
HCl hauv plab yog dab tsi?
hydrochloric acid hauv cov kua txiv hmab txiv ntoo zom cov zaub mov thiab cov enzymes digestive faib cov proteins. Cov kua qaub kua qaub kuj tua cov kab mob. Cov hnoos qeev npog lub plab phab ntsa nrog cov txheej tiv thaiv.
