Gastric HCl yog zais los ntawm cov hlwb tshwj xeeb parietal nyob rau hauv lub plab corpus , tsim kom muaj H+kua txiv plab uas yog 3 lab lub sij hawm ntau dua li cov ntshav thiab cov ntaub so ntswg. Cov txheej txheem yog tswj los ntawm ib tug complex system ntawm endocrine hlwb thiab neurons.
gastric acid secreted nyob qhov twg?
Acid secreted los ntawm parietal cells nyob rau ob feem peb (lub cev) ntawm plab. Gastric acid pab zom mov los ntawm kev tsim cov pH zoo rau pepsin thiab gastric lipase thiab los ntawm kev txhawb nqa pancreatic bicarbonate secretion.
kua txiv plab zais li cas?
plab zais zis yog txhawb nqa los ntawm kev ua noj (cephalic theem) thiab tuaj txog ntawm cov zaub mov hauv plab (pas plab). Kev tuaj txog ntawm cov zaub mov hauv txoj hnyuv kuj tseem tswj cov plab hnyuv siab raum (theem plab hnyuv). Cov kua dej secreted muaj hydrochloric acid, pepsinogen, intrinsic factor, bicarbonate, thiab mucus.
Qhov chaw tso kua txiv gastric yog dab tsi?
Acid secreted los ntawm parietal cells nyob rau ob feem peb (lub cev) ntawm plab. Gastric acid pab zom mov los ntawm kev tsim cov pH zoo rau pepsin thiab gastric lipase thiab los ntawm kev txhawb nqa pancreatic bicarbonate secretion.
piv txwv ntawm plab hnyuv yog dab tsi?
Proteases: Pepsinogen, ib qho zymogen tsis ua haujlwm, yog tso rau hauv cov kua txiv hmab txiv ntoo los ntawm ob lub qog hlwb thiab cov hlwb tseem ceeb. Ib zaug secreted,pepsinogen yog qhib los ntawm plab acid rau hauv lub active protease pepsin, uas yog lub luag hauj lwm loj rau lub plab lub peev xwm los pib zom cov proteins.
