Zakudya, Mavitamini, Mucus, ndi Zambiri
Mukangoyambitsa chakudya m'kamwa mwako mimba imayamba kumasula timadziti tam'mimba. Kusakaniza kwa madzi kumathandizira kuthetsa chakudya pakadutsa mimba ndipo kuyambitsa chimbudzi chimayamba.
Kodi timadzi timene timapanga ndi chiyani? Tiyeni titenge ulendo wa gawo loyamba la dongosolo lanu lakumadya ndikupeza.
Momwe Thupi Lanu Limapangidwira Mimba Yamakono
Chakudya chimene mumayaka ndi kumeza chimatchedwa bolus.
Zimasakanikirana ndi timadzi ta timadzi timene timagwiritsa ntchito zipangizo zapadera zomwe zimapezeka m'mimba mwanu. Amaphatikizapo zipsera za mtima pamtunda, m'mimba mwa m'mimba mwake, komanso m'matumbo a pyloric m'mimba kapena m'munsi mwa m'mimba.
Zilonda zonsezi zimakhala ndi maselo omwe amapanga zigawo zina zomwe pamodzi zimatchedwa timadziti tam'mimba. Maselo amkati amatulutsa bicarbonate ndi mucous, maselo a parietal secrete hydrochloric acid, maselo akulu amachititsa pepsinogen, ndi maselo a enteroendocrine amatulutsa mahomoni osiyanasiyana. Komabe, sizinthu zonse za mmimba zili ndi mtundu uliwonse wa selo.
Kuphwanya Mavitamini a Gastric
Madzi a m'mimba amapangidwa ndi madzi, electrolytes, hydrochloric acid, michere, ntchofu, ndi chinthu choyambirira.
Hydrochloric acid ndi amphamvu ya asidi yosungidwa ndi maselo a parietal, ndipo imachepetsa pH m'mimba mwako. 2. Hydrochloric acid imatembenuza pepsinogeni kukhala pepsin ndikuphwanya zakudya zosiyanasiyana kusiyana ndi zakudya zomwe mumadya.
Amapha mabakiteriya omwe amabwera ndi chakudya chanu.
Pepsinogen imadziwika ndi maselo akulu, ndipo ikapezeka pamaso pa hydrochloric acid, imatembenuzidwa kukhala pepsin. Pepsin amathyola mapuloteni apamwamba ndi apamwamba kuti apange tizilombo toyambitsa matenda m'mimba timene timagwira ntchito.
Gastric lipase ndi dokotala wina wosakanikirana wopangidwa ndi maselo akuluakulu. Zimathandiza kuswa mafuta ochepa ndi apakatikati.
Amylase amapezekanso mu timadziti tam'mimba, koma sikumapangidwa ndi m'mimba. Enzyme iyi imachokera ku saliva ndipo imayenda limodzi ndi bolus m'mimba. Amylase amathyola chakudya, koma alibe nthawi yochuluka yogwira ntchito m'mimba chifukwa asidi amasiya. Koma ndizobwino, intestine yanu yaying'ono imapangitsa kuti amylase apite patsogolo.
Chinthu choyambirira chimayikidwa ndi maselo a parietal ndipo ndi kofunikira kuti thupi lanu lizidya vitamini B-12. Izi ndizofunika kuti machitidwe amanjenje amatha kugwira ntchito komanso kupanga maselo a magazi.
Pomaliza, timadziti timakhala ndi madzi ndi ntchentche. Mankhwalawa amavomerezedwa ndi maselo a khosi ndipo amathandizira kuvala ndi kuteteza mimba yanu m'mimba mwa asidi.
Zonsezi Zimagwirira Ntchito Pamodzi
Minofu ya m'mimba yanu imapuma ndi kusakaniza kusakaniza bolus ndi zonsezi. Madzi osakaniza amatchedwa chyme. Mukakonzeka, mimba yanu imadumpha m'mimba yomwe imatulutsa chimbudzi ndikupangidwanso.
