Hydrochloric acid nyob rau hauv lub plab: cov nuj nqi thiab lub ntsiab lus

Lub secretion ntawm pais plab kua txiv Nws tshwm sim los ntawm cov lag luam ntawm lub pais plab mucosa. Nws yog ib tug tsis muaj kob, ntxhiab kua nrog me me nais ntawm hnoos qeev. Tej txawv los ntawm no coob, xws li hloov cov xim thiab ceev, lawv hais tias muaj teeb meem nrog rau cov hnyuv ib ntsuj av. Complex muaj pes tsawg leeg ntawm lub pais plab kua txiv vim nws ua ntau yam pais plab mucosal hlwb. Nws lub ntsiab tivthaiv yog hydrochloric acid, uas, nyob rau hauv lem, raws concentrated muaj pes tsawg leeg.

Muaj pes tsawg leeg ntawm lub pais plab kua txiv

Nyob rau hauv tas li ntawd mus hydrochloric acid nyob rau hauv lub pais plab kua txiv muaj cov nram qab Cheebtsam

1. Bicarbonates (lawv neutralize lub dejnum los ntawm hydrochloric acid nyob rau hauv lub plab phab ntsa).
2. Pepsinogen, xa mus rau hauv pepsin (tus tom kawg yog koom nyob rau hauv lub neej puas ntawm cov nqaijrog). Pepsin yog muab faib mus rau lwm lub tsev neeg ntawm enzymes, txhua tus uas muaj nws tus kheej muaj nuj nqi.
3. Hnoos qeev (nws kuj tiv thaiv lub mucosa ntawm kev puas tsuaj).
4. Tsev fuabtais tau (ib qho enzyme uas yuav pab tau nqus _B12).

Txawm li cas los, ib tug loj feem ntawm pais plab kua txiv yog tseem precisely hydrochloric acid. Nyob rau nws yuav tsum tau los sib tham.

Yuav ua li cas yog lub hydrochloric acid?

Nws khoom parientalnye hlwb ntawm lub pais plab qog, nyob rau hauv qab ntawm lub cev thiab lub cev. Nyob rau hauv essence, cov txheej membrane yog muab faib ua ob peb qhov chaw: ib tug ua hydrochloric acid, thiab lwm yam - nws allocates neutralizing bicarbonates. Nws yog noteworthy tias cov txiv neej parientalnyh hlwb yog ob peb lub sij hawm siab tshaj rau cov poj niam.

Cov ntsiab lus ntawm lwm yam acids nyob rau hauv lub plab me ntsis. Yog li ntawd, yog hais tias nws yog kuaj lactic acid, nws yog hais tias lub hydrochloric acid yog ua nyob rau hauv me me (tsawg pH ntawm lub plab) los yog tsis ua rau tag nrho cov. Cov yav tas tej zaum yuav qhia ntawm xws loj failures raws li Oncology.

Hydrochloric acid nyob rau hauv lub plab muaj ib tug muaj zog concentration theem - nws yog 0.3-0.5% (los yog 160 mmol / l). Nws muaj pes tsawg leeg yog li ntawd concentrated tias tsis muaj lub pais plab kua txiv thiab txheej membrane kev tiv thaiv tshuaj, nws yuav hlawv nws tus kheej lub plab. Uas yog vim li cas cov tsis muaj plab hnoos qeev, ib tug neeg muaj gastritis los yog duodenal rwj. Cov acid yog tam sim no nyob rau hauv lub plab txhua lub sij hawm, tab sis nyob rau hauv teb mus rau lub txais daim ntawv ntawm cov zaub mov tsub kom nws tus naj npawb. Basal secretion ntawm hydrochloric acid (i.e. thaum sawv ntxov) yog 5-7 mmol / hr.

Healthy plab ua mus txog 2.5 litres ntawm hydrochloric acid ib hnub!

Tso pa tawm ntawm hydrochloric acid muaj 3 theem.

1. Cov tshuaj tiv thaiv rau tus saj thiab tsis hnov tsw ntawm khoom noj khoom haus. Yog pib thiab yog kis tau los ntawm cov Cns rau pais plab hlwb los ntawm lub paj txoj.
2. Tom qab tsoo cov zaub mov nyob rau hauv lub cev tshaj ib tug loj theem pib. Gastrin ua rau parientalnye hlwb los ntawm stimulating lub zus tau tej cov hydrochloric acid.
3. Cov theem kawg yuav pib tom qab ntaus chyme (twb nqis zaub mov) mus rau hauv lub duodenum. Vim ua plab hydrochloric acid ua somatostatin - nws blocker.

Yuav ua li cas zog ua hydrochloric acid nyob rau hauv lub plab?

Ua ntej ntawm tag nrho cov, nws pab zom cov zaub mov, tua feem ntau cov kab mob uas nkag mus rau cov zaub mov mus rau hauv lub plab, uas slows los yog txawm txwv tsis pub putrefaction.

Yuav ua li cas yog cov kev khiav dej num ntawm hydrochloric acid nyob rau hauv lub plab? Hauv qab no yog ib daim ntawv teev cov lus pom hais tias lo lus nug.

• Denaturation ntawm cov proteins (qhov no yog kev puas tsuaj ntawm lawv cov molecular qauv) thiab lawv o.
• Kom ntawm pepsinogen, uas yog hloov dua siab tshiab rau hauv pepsin - ib qho ntawm feem tseem ceeb enzymes uas ua txhaum down proteins.

Txo pais plab acidity

Tsis tshua muaj acidity tshwm sim nyob rau qhov kev nyuaj siab thiab inflammatory kab mob. Qhov no tshwm sim vim excitation ntawm lub sympathetic lub paj hlwb, uas ncaj qha muaj feem xyuam rau zus tau tej cov pais plab kua txiv. Tej lub acidity deteriorating cov zaub mov zom cov zaub mov thiab lub plab ntswj. Khoom noj khoom haus nyob rau hauv cov kab noj hniav pib mus rau rot, ua hais tawm ntawm pathogenic cov kab mob. Tus txiv neej raug kev txom nyem los ntawm flatulence thiab xeev siab. Cov yav tas yog ib lo lus teb rau ib tug spasm ntawm lub plab. Ntxiv mus, nquag lov tus txheej txheem ntawm haum cov as-ham uas muaj nyob rau hauv peb cov zaub mov, uas ua rau yus muaj kev cuam tshuam ntawm cov tag nrho lub cev. Los ntawm txoj kev, nyob rau lub hauv paus ntawm lub ntuj txo nyob rau hauv lub pH tom qab 40 xyoo, ib tug neeg pib muaj hnub nyoog sai heev. Hais tias yog, tus hydrochloric acid nyob rau hauv lub plab yuav ua tau muaj kev cuam tshuam cov kev kho mob ntawm tag nrho cov kab mob.

Mob plab, tag overgrowth ntawm cov kab mob xws li kev tiv thaiv nuj nqi pib, ua rau o zoo nkaus li. Nws yog kho nrog cov tshuaj uas inhibit qhov ntxiv zus tau tej cov hydrochloric acid - thiab lub vajvoog yog kaw. Txiv neej lossi yuam kom mus saib tus kws kho mob.

Txawm kub siab, uas peb siv los coj lub txim ntawm kev ua qhov nyiaj ntawm pais plab kua txiv yog pom tias yuav tau ib yam khoom ntawm acetic acid fermentation.

Nyob rau hauv cov neeg mob uas pais plab pib nquag tsim lactic acid. Vim hais tias ntawm cov tsis muaj peev xwm ntawm lub plab los tsim txaus hnoos qeev, nws puas tsuaj rau lub cev phab ntsa. Nyob rau hauv xws li mob thiaj paub hais tias - gastro.

Parasites thiab txo pais plab acidity

Nyob rau hauv ib tug noj qab nyob zoo plab cab tsis tau nyob (tab sis yog qhov no tsis txwv lawv localization nyob rau hauv lwm yam kabmob thiab tshuab ntawm lub cev), raws li lawv cia Burns hydrochloric acid. Tab sis sai li sai tau raws li nws dauv, cab zos pib vam, ua heev unpleasant cov tsos mob. Txawm ntau disturbed haum cov as-ham, muaj txoj kev pheej hmoo ntawm cov zaub mov tsis haum (yog cab "tsis nyiam" Noj cov khoom uas zaub mov).

Nce acidity ntawm lub plab
