kupatsanura mumasero

Omumuviri dzinokosha nhengo kuti secrete pakugadzira vanoshingaira zvinhu - makemikari. Vane zvoutachiona catalysts kuti rikurumidze kufamba nemakemikari, asi haana kuiswawo pakati Zvinoumba zvinhu zvayo. Vanewo kunzi zvakavanzika.

Kusiyanisa shwanu nechomukati, kwokunze uye yakavhenganiswa secretion. Kusunungurwa yokutanga muropa zvakavanzika. Somuenzaniso, ari pituitary shwanu, riri mu mujinga uropi, synthesises kukura kemikari, izvo anoita izvi. Uye adrenal mumasero secrete adrenaline. fuma Izvi zvinobatsira muviri kukurira anoshungurudza ezvinhu nokuda achikurudzira mauto ayo ose. Rwatata chinhu zvakasiyana. Inobereka mahormone kuti dzave vakaudza muropa uye zvakananga mukati mhango pakati zvomukati (zvikurukuru, mudumbu).

mumasero zvomudumbu akadai mate uye chiropa, muri exocrine mumasero. Muvanhu, naivowo zvinosanganisira misodzi, mukaka, ziya uye nevamwe.

The zvomudumbu yevanhu shwanu

Izvi nhengo secrete makemikari kuti kuputsa yakaoma Organic zvinhu kupinda nyore, izvo zvinogona nyura kubudikidza zvomudumbu hurongwa. Achipfuura turakiti, mapuroteni dzaputswa kune amino acids, dzakaoma makabhohaidhiretsi - kune nyore lipids - kuti mafuta acids uye glycerol. Izvi hazvigoni chinozoiswa nomuviri kubudiswa zvokudya achishandisa kwemeno. Zvinogona chete kuti zvomudumbu mumasero. Funga mashandiro chiito kwavo zvakawanda.

mumasero zvomudumbu mudumbu

In chinonyanya nevazukuru chikamu zvomudumbu turakiti mucosa mumasero secrete ayo mhango chaiyo chirungiso - iri gastric muto. Zviri pachena mvura, asi ane acidic svikiro. The sezvamunoita zvinosanganisira gastric mucin, amylase uye maltase makemikari kuti anamatire mapuroteni uye lipids, uye hydrochloric acid. Yokupedzisira kunomutsa injini nezvebasa mudumbu, neutralizes utachiona hunokuvadza, anodzivira putrefaction.

zvokudya zvakasiyana uri munhu mudumbu imwe nguva. Carbohydrate - mana maawa, mapuroteni uye mafuta - kubva nhanhatu masere. Mvura hadzigari mudumbu, kuwedzera mukaka, riri kushandurwa pano kupinda ruomba.

rwatata

Ndicho chete zvomudumbu shwanu, inova yakavhenganiswa. It riri shure mudumbu, chinoguma zita rayo. Munguva duodenum inobereka zvomudumbu facial. Ndiyo exocrine rwatata. Zvakananga kupinda ropa inobudisa zviri hormone jekiseni uye glucagon inodzora carbohydrate muviri mumuviri womunhu. Panyaya iyi, muviri anoita kwemakemikari anobudiswa shwanu.

chiropa

Zvomudumbu shwanu secretory uyewo ishande, achidzivirira, chinjanai uye chakaita zvokugadzirwa ushande. Uye kuvonga ichi zvose kuti chiropa. Ndicho chikuru mumatumbu shwanu. Zvinonzi kuramba kuumbwa ducts bile. Zviri chinovava zvokunwa greenish-yellow ruvara. Inoitwa mvura, bile acids vavo munyu, uyewo makemikari. chakavanzika chiropa chake secretes kupinda duodenum, umo yokupedzisira cleavage (emulsification) kwemafuta uye disinfecting zvinhu zvinokuvadza nhengo.

Sezvo cleavage polysaccharides rinotanga nomumukanwa carbohydrate zvokudya ndiro rinonyanya digestible. Zvisinei, mumwe anogona kusimbisa kuti pashure romuriwo Salad nzara anouya nokukurumidza. Nezvezvokudya angarayira kuti upise mapuroteni zvokudya. Zviri zvinoshingaira kukosha, uye chirongwa kukamurwa uye kugaya rinovapo yakareba.
