Cov kua qaub. Cov kua qaub hauv plab, kua txiv plab, lossis qee zaum hu ua kua qaub plab, yog cov kua dej zom ua kua hauv lub plab thiab ua los ntawm cov kua qaub, poov tshuaj chloride, thiab sodium chloride.
Ua qhov no hauv kev txiav txim siab, dab tsi yog lub hauv paus tseem ceeb ntawm kua txiv plab?
Cov kua txiv hauv plab yog tsim los ntawm dej, electrolytes, hydrochloric acid, enzymes, mucus, thiab qhov tseem ceeb. Hydrochloric acid yog cov kua qaub uas zais los ntawm cov cell parietal, thiab nws txo qis koj lub plab pH mus rau ib puag ncig 2.
Tom qab ntawd, lo lus nug yog, lub hauv paus thiab dab tsi ua haujlwm ntawm cov kua qaub hauv plab? Mob plab kua txiv yog tsim los ntawm cov zom zaub mov, hydrochloric kua qaub thiab lwm yam tshuaj uas tseem ceeb rau nqus cov as -ham - li ntawm 3 txog 4 litres ntawm plab kua txiv tau tsim nyob rau ib hnub. Cov tshuaj hydrochloric acid nyob rau hauv lub plab kua txiv zom cov zaub mov thiab cov zom zaub mov zom zom cov protein.
Kuj paub yog, dab tsi yog lub luag haujlwm ntawm cov kua qaub hauv plab?
Acid hauv peb plab plays ib qho tseem ceeb lub luag hauj lwm hauv lub cev tiv thaiv kab mob los ntawm kev tua cov kab mob phem thiab cab uas tau noj nrog zaub mov. Lub plab acid ua kom cov enzyme pepsin xav tau rau kev zom cov protein. Lub plab acid cov cim qhia rau tus txiav ua cov kua txiv zom thiab cov enzymes txhawm rau zom zaub mov ntxiv.
Dab tsi yog qhov molarity ntawm plab acid?
Kev zais thiab Dilution Cov hlwb ua lub luag haujlwm tsim cov HCl hauv koj plab yog cov hlwb parietal, thiab cov tshuaj uas lawv zais cia muaj qhov siab ntawm 160 millimoles ib litre - hauv lwm lo lus, 0.16 moles ib litre, sib xws rau pH ntawm 0.8.

Lub luag haujlwm tseem ceeb ntawm cov hauv paus hauv paus yog dab tsi?
Basal ganglia tau cuam tshuam nrog lub paj hlwb, thalamus, thiab lub hlwb, nrog rau ntau qhov chaw hauv hlwb. Lub hauv paus ganglia cuam tshuam nrog ntau yam haujlwm, suav nrog kev tswj ntawm kev txav mus los lub cev muaj zog, kev kawm paub txheej txheem, kev coj tus cwj pwm, kev txav qhov muag, kev paub, thiab kev xav
Lub tshuab ua pa ua lub luag haujlwm dab tsi hauv cov kua qaub hauv paus?
Cov kab mob ua pa ua rau muaj kev sib npaug ntawm cov kua qaub thiab cov hauv paus hauv lub cev los ntawm kev tswj cov ntshav qib carbonic acid (Daim duab 2). CO2 nyob rau hauv cov ntshav tau yooj yim reacts nrog dej los tsim carbonic acid, thiab cov theem ntawm CO2 thiab carbonic acid nyob rau hauv cov ntshav yog nyob rau hauv equilibrium
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
Dab tsi yog cov khoom siv tseem ceeb ntawm lub hauv paus paj hlwb thiab lub paj hlwb sab hauv?
Lub paj hlwb muaj ob ntu tseem ceeb: Lub hauv paus paj hlwb yog tsim los ntawm lub hlwb thiab tus txha caj qaum. Lub paj hlwb peripheral yog tsim los ntawm cov hlab ntsha uas tawm ntawm tus txha caj qaum thiab txuas mus rau txhua qhov ntawm lub cev
