Tib neeg digestive ib ntsuj av. Tus qauv ntawm lub plob tsis so tswj

plob tsis so tswj qauv muaj xws li nyias thiab tuab feem. Nyias department originates ncaj qha tom qab lub plab. Nyob rau hauv neeg laus, ib tug ntev ntawm txog tsib meters. Lub xeev ntawm no department tsis hais lub hav zoov ntawm tej teeb meem los yog pab microorganisms. Nyob rau hauv muaj ntau yam tej yam kev mob uas ua rau muaj kev cuam tshuam ntawm cov enzyme tshwm sim Wednesday haum rau tu tub tu kiv ntawm microbes nyob rau hauv nws. Pathogenic microbes nqa tau tus kab mob, uas yog nrog los ntawm zawv plab heev, tsam plab, rumbling, mob nyob rau hauv lub puj ntaws. Tsis-pathogenic microbes ua rau tsis xis thiab o nyob rau hauv lub plab mog.

Cov hnyuv loj yog ib tug continuation ntawm cov hnyuv. Lub ciam teb ua hauj lwm pab raws li txheej damper therebetween. Nws tiv thaiv allergic ntawm cov ntsiab lus ntawm kab mob thiab muaj roj card rov qab mus rau hauv ib tug nyias seem. txheej txheem (appendix) yog nyob rau ntawm no nrov plig plawg.

Tus qauv ntawm cov hnyuv, nyob rau hauv particular, nws tuab card, muaj xws li cov cecum, ascending, transverse thiab nqis nyuv thiab sigmoid, uas ua rau lub qhov quav. Nws yog fundamentally sib txawv ntawm tus qauv ntawm ib nyias card. Tuab department kuj ua ib tug txawv kiag li muaj nuj nqi.

Tej microflora yog suav tias yog dynamically kuas, complex ecosystem. S yam ntxwv kev muaj pes tsawg leeg, uas muaj xws li ntau tshaj li tsib puas cov hom ntawm cov kab mob. Lub ntsiab cov neeg sawv cev ntawm bifidobacteria muaj xws li co thiab aerobic lactobacilli.

Plab hnyuv microflora ua kev cai ntawm cov roj uas txhaws metabolism thiab cov kua tsib acid tiv thaiv txoj kev loj hlob ntawm pathogenic microorganisms, yog li kom ntseeg tau, stability (colonization kuj) ntawm lub cev. Ntxiv mus, lub puab ecosystem muab kev koom tes nyob rau hauv lub enzymatic kev ntawm cov protein, cov roj zom cov zaub mov thiab assimilation ntawm kev noj haus fiber, high-molecular carbohydrates thiab nucleic acids.

Plab hnyuv microflora yog ib tug active koom tes ntsha metabolism, synthesis ntawm antibacterial kev ua si, vitamins K, C, ascorbic acid. Yog li, tag nrho cov zog kuj mus phiv influences los ntawm sab nraum. microflora zog kuj muaj xws li detoxification ntawm endogenous thiab exogenous substrates. Txawm li cas los, ib co kab mob no tau hloov cov tshuaj muaj pes tsawg leeg ntawm tshuaj lom, rendering lawv harmless. Plab hnyuv ecosystem muab kev koom tes nyob rau hauv lub stimulation ntawm kom (locomotor ua si) ntawm lub cev thiab lub normalization txheej txheem ntawm tshem tus txheem ntawm lub cev.

Resident microflora yog muab faib mus rau hauv (ib qhov), ib tug nraum (ib ntus) non-pathogenic (nqi hluav taws xob), conditionally pathogenic (pab tau nyob rau hauv me me qhov ntau thiab nyob rau hauv txoj cai qhov chaw), pathogenic (teeb meem yuav ua tau kab mob). Muaj pes tsawg leeg thiab tus nqi ntawm cov kab mob tam sim no yog lossi hloov, tab sis tus piv ntawm kom muaj nuj nqis thiab zoo yog txiav txim tau. Yog li, lub dynamic tshuav nyiaj li cas yog khaws cia. Nrog ib tug ntse tsis txaus tshwm sim dysbiosis.

Raws li hais saum toj no, cov hnyuv tau ntau yam zog. Nyias seem luag hauj lwm rau qhov kev siv ntawm cov yooj yim mechanisms ntawm kev zom zaub mov thiab haum cov as-ham rau hauv lub qog thiab cov ntshav. Nyob rau hauv cov ntaub ntawv no, lub plab hnyuv kom yog muab los ntawm lub cev ua si puab nplhaib thiab txheej longitudinal nqaij. Thaum zoo li no yog nqa tawm nrog stirring chyme kua txiv secreted los ntawm lub pancreas thiab los ntawm lub cev nws tus kheej, raws li zoo raws li nce qib ntawm chyme. Npag qauv ntawm cov hnyuv tso cai rau koj mus ua ib tug nyias seem zoo khiav lag, pendulum, thiab tonic peristaltic lus.

Tuab lub cev department ua cov kev ua ntawm ib tug reservoir. Muaj tshwm sim rau cov ntsiab lus tsub zuj zuj thiab periodic tshem tawm ntawm lub zaub mov lub cev. Plab hnyuv nqaij qauv nyob rau hauv qhov chaw no tso cai rau koj los mus ua kom peristaltic twj, pendulum, anastaltic, propulsion yuav txo tau thiab zoo khiav lag.
