Duodenum: kugawidwa ndi kuikidwa magazi

Ndi dzina la gawo ili la matumbo, mukhoza kuganiza kuti ndiloling'ono. Zolemba khumi ndi ziwiri ... Deta yamakono imati kutalika kwake ndi 25-30 masentimita. Monga mukuonera, sizitalika konse. Koma imakhala yokhayokha mu dipatimenti yodziimira ya m'mimba, yomwe imaphatikizapo khungu ndi leamu. Kodi duodenum ili kuti ndipo ikuchita chiyani?

Kuwonekera kwake pa khungu kuli m'chigawo cha epigastric. Danga limeneli pamimba, lopangidwa kuchokera pansi pa mzere womwe ukhoza kuyendetsedwa m'mphepete mwa nthiti, ndipo kumbali zonse za dera lino kuli kutsika kwa nthiti.

Ngati tilankhula za ntchito ya duodenum, ndiye kofunikira kutchula ziwiri - kusintha kwa mankhwala ndi chakudya chake. Mu dipatimenti iyi, zitsulo zochuluka zimatengidwa, chifukwa matenda a mucosa wa intestine angakhale limodzi ndi mawonetseredwe a kuchepa kwa magazi m'thupi.

Pano mitsempha yotuluka m'magazi imatsegulidwa , ndipo motero chimbudzi chimakhala chotheka. Pakati pa mimba ndipo gawo ili la m'matumbo ndilo cholepheretsa chakudya - mlonda wa pakhomo, yemwe amachititsa kusintha kuchokera m'mimba kupita m'mimba. Komabe, nthawi zina zakudya zimayenda mosiyana - ndi kusanza kwakukulu kuchokera kwa munthu kupita kunja kwa zakudya ndi bile, ndi bile wothira chakudya mu duodenum.

Chakudya chimene chimabwera kumatumbo ang'onoang'ono m'mimba chimakhala ndi asidi okwera kwambiri, omwe ndi aakulu kwambiri moti amatha kuyambitsa zilonda zam'mimba. Mwamwayi, izi sizichitika kawirikawiri, chifukwa pakhomopo la duodenum pali madontho a Brunner omwe amachititsa kuti zinthu zisawonongeke. Kodi duodenum ndi chiyani?

Mapangidwe ake sangathe kufotokozedwa popanda kufotokoza malipoti pa madontho omwe amachokera kumatenda am'mimba. Funso lochititsa chidwi, chifukwa anthu osiyana akhoza kukhala ndi maonekedwe a dera lino. M'dera linalake la m'matumbo, pharynx ya papillae, mazira awiri ndi awiri akhoza kuyenda. Anthu ambiri ali ndi imodzi. Koma izi sizingakhale zosiyana. Nthawi zina palinso njira ina yowonjezera pamapangidwe, komabe ndizosiyana ndi malamulo.

Mu chimbudzi sizing'onozing'ono zokha (chiwindi ndi ziphuphu) zimakhudzidwa, komanso zimatuluka m'matumbo. Amayambitsa mavitamini a glands lalikulu. Mu duodenum mubwere mazira ndi molunjika kuchokera ku chiwindi, ndi kuchokera ku ndulu. Nthawi zina, mukakhala ndi miyala yowala, amatha kulowa mkati mwa matumbo ndi kuvulaza. Zomwe zimapangitsa kuti mafuta asweke, motero mbali imeneyi ya intestine imayamba kuyamwa.

Komanso, duodenum ikhoza kuponyera zinthu zomwe zimapangitsa mlonda wam'zipata kutseguka, ndikofunikira kuti mudye gawo latsopano la chakudya. Amathandizanso pomanga njala. Kuwonjezera apo, gawo ili la matumbo, kupyolera mu kupanga mahomoni, limakhudza chiwindi, zomwe zimachititsa kuti wotsirizirayo asungunuke kwambiri bile.

Ndi duodenum yomwe imachotsedwa ku chimbudzi cha dokotala, pamene opaleshoni ikuchitidwa kuti muchepetse kunenepa kwambiri. Izi zimatsimikizira ntchito yofunika kwambiri mukutenga gawoli m'matumbo. Inde, munthu amayamba kupeza zakudya zochepa, koma nthawi yomweyo amakhala mtundu wa olumala, ndicho chifukwa chake anthu oganiza bwino amapeza njira zina zothandizira.

M'mimba yaing'ono, chakudya chimathamanga kwambiri kuposa m'mimba. Koma izi sizikunenedwa zambiri, chifukwa matumbo samadyetsa chizindikiro cha njala, monga mmimba imachitira. Ndipo chifukwa chimayamba kumvetsera, kokha ngati matendawa atayamba.

Ichi ndi chilendo chosazolowereka, chifukwa, pokhala chaching'ono, chiri ndi malo omwe matumbo ndi mamita 500 ayenera kukhala nawo. Kodi izi zingatheke bwanji? Mlanduwu mu villi, mapepala ndi makola, omwe amachulukitsa malo oyamwa.

Thupi ili liri ndi zinsinsi zambiri. Mwinamwake ndi inu amene mudzawalowera iwo?
