Kuwombera m'mimba mwa m'mimba

Udindo wamatumbo aang'ono m'mimba ndi wofunika kwambiri ndipo, tinganene kuti, ndilo gawo lomalizira mu chakudya cha hydrolysis kwa zinthu zomaliza zomwe zili zofunika kwa thupi lathu.

Zambiri zokhudza matumbo aang'ono aumunthu

Maseŵera akuluakulu a chimbudzi amatsirizika m'mimba yaing'ono, yomwe ili m'litali kwambiri, ndi malo oyamwa pafupifupi 200 square meters. Mu gawo ili la tsamba la m'mimba kuti zakudya zambiri, komanso poizoni, poizoni, mankhwala, ndi maantienobiotics omwe amamwa ndi njira ya pamlomo amachotsedwa. Kuwonjezera pa kuyamwa, kuyamwa ndi kuyendetsa zinthu zonsezi, ntchito za kutsekemera kwa mahomoni komanso chitetezo cha mthupi zimagwiritsidwa ntchito m'mimba yaing'ono.

Katumbu kakang'ono kamaphatikizapo madipatimenti atatu:

• duodenum;
• liwu;
• the ileum.

Komabe, pakati pa dipatimenti iwiri yapitayi mulibe malire.

Zigawo zonse za m'mimba mwachisawawa zimakhala zonyezimira ndipo zimakhala ndi zipolopolo zinayi:

• mucous membrane;
• submucosal;
• muscular;
• serous.

Kodi chimbudzi chimakhala bwanji m'mimba?

Chakudya kuchokera mmimba chimalowa m'dera la duodenal, komwe kumawoneka kuti amakhala ndi bile, komanso pancreatic ndi m'matumbo a m'mimba. Kuchulukira m'mimba m'mimba mwa munthu kumagwira ntchito kwambiri kuti adye zakudya zowonjezera, kotero kuti pano ndikuti chakudya chomaliza chodya chimapezeka ndi chithandizo cha m'mimba yamadzi, yomwe ili ndi magulu atatu a michere. Pankhaniyi, pali mitundu iwiri ya chimbudzi m'matumbo aang'ono: mphala ndi parietal. Mosiyana ndi mitsempha yamagetsi yambiri m'mimba yamatumbo pafupifupi 80% mwa magawo omaliza a hydrolysis ndipo panthawi imodzimodziyo chakudya cha zinthu zomwe amadya chakudya.

Mavitamini opangidwa ndi glands a m'mimba mwazing'ono amatha kugawa mitsempha yaifupi ya peptide ndi shuga, yomwe kufika kumeneko chifukwa cha "ntchito" yoyamba ndi chakudya cha ziwalo zina. Pambuyo powonongeka kwathunthu kwa zakudya mu shuga , mavitamini, amino acids, mafuta acids, mchere, ndi zina zotero, njira yofunikira ya kuyamwa kwawo m'magazi amachitika. Motero, maselo a thupi lonse la munthu amadzazidwa.

Komabe maselo a epithelium a m'matumbo ang'onoang'ono amapanga matope omwe amatha kudutsa, ndipo mamolekyu osasinthika a wowuma kapena mapuloteni, mwachitsanzo, sangalowe mkati ndipo amatengedwa kuti apitirize "processing".
