Zvomudumbu hurongwa - hwaro ishande yose yomuviri

The zvomudumbu Hurongwa kunoita mabasa evanhu nokuda chokuendesa zvakafanira zvinovaka muviri kushandiswa simba rine uye chivakwa zvinhu. Izvi zvinhu kupinda muviri kuburikidza zvomudumbu turakiti, zvachose kureba vanenge 10 metres uye kuva yose rokuwedzera uye marwadzo ose mhango.

The nemamiriro zvomudumbu kwevanhu mamiriro dzinosanganisira: buccal mhango, pharynx, yegurokuro, dumbu, rwatata, chiropa, gallbladder, muura uye ura diki.

Oral mhango. Muchikamu ichi zvomudumbu hurongwa kunoitika zvakananga assaying chikafu, kuona kwayo zvemakemikari uye mumuviri nemigumisiro. Kutsenga zvokudya ndohwaJehovha wechipiri mhando kukanganisa, uye ichi Paunotanga kushanda wegadziriro kunoenderana unhu okutambirwa uye kuitwa nezvinovaka muviri. Kwete pasina chikonzero, nyanzvi dzakawanda angarayira sei kutsenga chikafu, iyo zvino pachena kuti mate yakaumbwa muna bolus.

Mate basa zvakarurama basa rinokosha kugaya zvokudya. Kunoumbwa zvinenge zvachose mvura (anenge 99%). Zviri mukati mucin mapuroteni chinowedzera adhesiveness, kuvapo lysozyme achibvumira decontamination zvokudya uye makemikari zvakadai amylase uye maltase ozeyewa muviri.

The anatomi of zvomudumbu ino kunoratidza kuti muviri anotevera dzaiita zvokutaurwa pharynx ndechokuti, inova tsandanyama nhengo nedzimwe maburi (nemumuromo mhango, nasal zvinoshandisa pakurima, kuti zvinoshandisa pakurima kuti yegurokuro uye dokeriro, uye pombi maviri pakati nzeve). Kuonana, nokuda spillage zvokudya ari kufema nzira, pamukova dokeriro rinosanganisira epiglottis.

The chaizvo inoshandiswa pakuparadza zvokudya nokuda rutapudzo pakati tsandanyama ari pharynx, kuburikidza icho anopinda yegurokuro uye kuburikidza diaphragm - mudumbu. Sezvo yegurokuro - a tsandanyama chubhu kuti nokuda rutapudzo pamusoro tsandanyama idzi zvokudya achawisirwa pasi.

The zvomudumbu Hurongwa zvinosanganisira mudumbu, iro riri pasi diaphragm iri repamusoro mudumbu. Nature mairi mawindo maviri akapa - kwezvavakaisa goho. The obturator wechipiri kuvhara tsandanyama zvakakwana simba (sphincter). Food iri rakaramba mudumbu kwenguva refu (maawa anosvika 11), izvo pasi kwemakemikari kurwisa kuti gastric muto, inova Hauoneki mvura ine hydrochloric acid. Zviri kuburikidza chazvo iri zvakananga akaita zvomudumbu ushande. Acid aivawo kunoparadza nezvainoita anwa utachiona. Naizvozvo, pedambudziko roku- zvinotapuriranwa rinowanikwa chiitiko kwezvirwere ari nemudumbu, izvo vakayambuka zvomudumbu hurongwa.

The zvichiguma chyme kubva dumbu kuburikidza sphincter migove zvishoma nezvishoma anopinda ura. The duku ura rinotanga pamwe duodenum wakasvinudza vanhuwo bile mutsinga dzinofamba nemukaka uye pancreatic mutsinga dzinofamba nemukaka. Kouya kuguma kugaya zvokudya nokuda kuitwa pancreatic muto uye bile.

kupatsanurwa zvokudya kubva ura duku zvishoma nezvishoma zvinoenda muura, ine kureba 2 mamita. Pane kwazvo kunyura mvura, uye vakasara zvokudya basa akatodzima kubva mumuviri. Nokuda vakawanda utachiona siyana ari dumbu, kuvandudzwa kugaya. Zvisinei, pane zvinhu zvisingafadzi. Saka, pasi Zvakaitwa tusingaoneki vanoparadzwa chikafu kare zvisingakoshi uye kusunungura chepfu yeimwe nokuda zvibviswe iyo rinoenderana chiropa.

Zvomudumbu System ibasa munhu chiropa rutivi rukuru. Shure zvose, izvi ndiko kuri zvomudumbu shwanu kuburikidza izvo vakachenesa uye venous ropa zvose kubva mudumbu, chirwatata uye ura.

Saka zvomudumbu maitiro - a panzvimbo kunzwisisa maitiro zvokudya kubudiswa mumuviri womunhu, mumwe nhengo iri basa basa, uye kukundikana kupfuura imwe chezvinonhuwira kuti mashandiro angatanga zvirwere nemudumbu.
