Rwatata pave mamwe mahormone?

Rwatata Kunoumbwa mapoka maviri: exocrine pokugara 98% uye pancreatic kenza - muchimiro zviduku inclusions pamusoro wayo pepasi.

Kwemakemikari anobudiswa dhipatimendi mhosva secretion ose gastric muto uye kuzvidzora pezvakaitwa kuitika duodenum uye zvomudumbu mvura makemikari inonyorovesa.

The kwemakemikari anobudiswa ndechokuti anokonzera kemikari kugadzirwa.

hormone basa

Rwatata unobereka mahormone maviri - jekiseni uye glucagon iri. The kwacho nokuti kuita glucagon kwaisanganisira Arifa masero, uye jekiseni zvinobatanidzwa pakugadzira Beta-masero. Kuwedzera mhando idzi mbiri masero rine simbi uye Delta masero mamwe iyo pave somatostatin.

Ndezvipi mahormone aibudiswa nerwatata

jekiseni kwevanhu rakakamurwa mhando mbiri: basal uye dzinovhurika.

Basal mhando kunoratidzwa muna zvinopinda muropa pasina kudiwa. Muenzaniso woga kwakadaro kunogona kuva kugadzirwa jekiseni, kana zvokudya hazvirevi ichiyerera kupinda mumuviri, i.e. usina chawadya.

Standards ropa shuga - kwete kupfuura 5,5 mmol / L, apo padanho jekiseni kuva 69 mmol / L.

Dzakawedzerwa nemashoko mhando inonzi zvipikirwa kunobva kudyiwa yezvokudya uye kugoverwa amino acids uye shuga muropa. Secretory basa mahormone izvi kunotaurwa stimulyativnomu anokonzerwa zvinodhaka kuti akaumbwa imwe sulfonylurea.

jekiseni dzishande kunoitika mumatanho maviri:

• Short - kemikari ichi kusvika ropa.
• Slow - zviri synthesizing kemikari.

Kunze kwavari, ipapo vari zvinoberekwa dzakasiyana-siyana anoenderana zvinhu zvinobatanidzwa zvomudumbu kwendangariro. Pamazita Izvi zvinoratidza makemikari zvinoberekwa nerwatata:

• Zvinhu kuti vaite mapuroteni - ndiko trypsin, chymotrypsin, carboxypeptidase A uye B, elastase, ribonuclease.
• Zvinhu inokwanisa digesting makabhohaidhiretsi: amylase, invertase, maltose, lactose.
• Zvinhu akafanirwa kuputsa kwemafuta. It cholinesterase uye lipase.

In Kana apo rwatata Haibudisi chero makemikari chipo, kana kukundikana kunoitika fermentopathy chokuita concomitant chirwere.

Basa mahormone

Basa rwatata iri pakuburitswa insulin yakakodzera uye glucagon ndiko kuchinja carbohydrate uye lipid muviri, uyewo simba pamusoro redistribution kuti shuga kubva kuna plasma kupinda tishu.

chikuru basa racho synthesize lipokaina unobereka basa ichivharira uye degeneration kuti chiropa masero.

Kana yakaoma rokushaya kana rwatata unobereka kukwana nhamba yeimwe yakadaro, hormone kukundikana rinotanga kushanda pezvakaitwa ane muviri, izvo zviri kukonzerwa wakakodzera kwete chete vawana, asi vachiberekwa malformations.

Kana rwatata unobereka kukwana jekiseni kemikari mari kunoitika chirwere - chirwere cheshuga. In yokunyanyisa zvakawandisa glucagon kunowedzera jekiseni kugutsikana uye kuderedzwa ropa shuga wevasungwa masero, izvo zvinozoita kunowedzera uwandu epinephrine. Zvadaro pane yomuropa - vasanyanye mano chiropa masero kuti kubudiswa shuga.

Kusavapo kana kunyanyisa kuperevedza somatostatin kunotungamirira kutyorwa-siyana dzinotsanagura nhengo basa iri kutyora pakuenzanisa metabolic kwendangariro.

Sei jekiseni

Worudzii mahormone anobudiswa nerwatata, akavaka kurovedza mafuta muviri yose muviri.

Pamberi paumbwe jekiseni, apo synthesis dzaro Beta-masero secrete ane fuma proinsulin. By pachayo haisi hormone. The Kutendeuka kwacho kunoitika pasi zvinoitwa yayo Golgi zvakaoma uye Kuwanikwa inokosha enzymatic yeimwe. Pashure nedanho raro kushanduka kupinda muchitokisi mamiriro zvichafambira kuti jekiseni. Zvadaro pane kunenge Absorção de Água kuti musana wake, apo akanga granulated uye akatumira kuchengetwa, apo zvichava kuwanikwazve panjodzi apo pasi muviri anonongedzera.

ino kunouya apo padanho shuga muropa apo masero kusunungurwa jekiseni inochengeterwa kwayo neutralization uye zvakakodzera kubudiswa kuti glycogen, kuwedzera ayo wevasungwa munguva chiropa masero tsandanyama rinenge somunhu nokutengesa simba nokuda muviri wose. Nokuda zvinokonzerwa jekiseni, yeplasma shuga yomuropa anogona nemhepo akakurumidza ndokudururira dzose.

Kana kuziva parameters yawo yakakwirira tigutsikane muropa riri ionekwe somureza kuti muviri anoruramisa zvakaipa zvakawedzera kusunungurwa kemikari chinobatanidza kuti kutadza kwakaita receptors anokonzera carbohydrate muviri, kuziva uye achabvisa ngozi iyi. Somugumisiro, rwunotanga kutanga chirwere inonzi cheshuga. Migumisiro yokuti makabhohaidhiretsi vari anwa, hadzina kupatsanurwa uye haagoni ozeyewa, ndokusaka miedzo ropa kuratidza yakakwirira nhanho yomuropa.

Zviratidzo zvirwere izvi pasina kuisa kunyanya nyota assays ari kuti chokuita shuga kwaniso yekubata unyoro. Saka, kwete neutralized muropa, kwahunokonzera kupera mvura mumuviri.

Chii chinoratidza kusunungurwa jekiseni

Rwatata anobereka makemikari uye mahormone, zvikuru tisingazvioni kunzwa kuchangotanga kuchinja yomuropa. Nokuda kwaizvozvo, uye munorwira anonongedzera kuti muviri kutanga paumbwe vawedzere uwandu jekiseni, kana kudiwa kuderedza uye kutumira chengetedza.

In zvinoitirwawo chirwere cheshuga, nezviduku zviri kwemakemikari anobudiswa mumasero vanosangana nokuchinja uye kuvhiringidzika mabasa anoitwa. Naizvozvo, chirwere cheshuga vane mazita mishonga kuti contraindicated kurishandisa nokuda mukuru zviri shuga, iyo muviri haagoni kurarama. It pastries uye zvihwitsi, uchi, carbohydrate zvokudya, uye shuga zvayo yakachena chimiro. An overabundance kweshuga muropa kunotungamirira yokunyanyisa kuneta nokuda Beta masero anokonzera jekiseni usage, uye zvingaita kuti rufu kuMhedziso.

glucagon

Rwatata unobereka glucagon ari Arifa mumasero. Intestinal mucosa interaglyukogon pave kemikari, riri rimwe synergist adrenaline. Izvi pancreatic kemikari anokonzera kuyerera kudzora lipolysis rayo velocity, uye anewo zvakananga kubatsira hepatic glycogenolysis.

The chikuru zvinokosha kushanda rwatata mumuviri womunhu ane vakasarudzwa mahormone siyana kuti pave kugaya uye Absorção de Água payo.
