Sechivako mudumbu rayo shanda

Dumbu (Lat. Gaster, ventriculus) chiri kuwedzera nemudumbu, kusikwa tangi rimwe zvaro, umo ozeyewa zvokudya inounganidzwa. Riri kurutivi rworuboshwe muviri ari hypochondrium. Akabatana wakavhomorwa kuburikidza mudumbu, rinotungamirirwa kumusoro uye kuruboshwe, kuti nechepasi uye kurudyi. The mudumbu mamiriro mhando anoratidzwa muchimiro chiredzo kana nyanga, kunyange kazhinji chimiro chayo dzingasiyana. Muviri kureba kazhinji 25-30 masendimita uye upamhi kusiyanisa kubva 12 kusvika 14 masendimita. Vachikwanisa zvinoenderana sei pane zvokudya. Kunyange zvakadaro, ayo avhareji Vhoriyamu 1-3 litres.

The dumbu iri yakabatana zvakawanda zvinokosha nhengo yacho abdominal mhango. Front ndiye pechiropa, musana chirwatata, akasiya itsvo uye adrenal omumuviri, rwatata uye duodenum. Saka, uyewo zvirwere pezvakaitwa zvingaita dumbu mumuviri izvi, kunyange zvakawanda zvakajairika neizvi mamiriro ezvinhu, apo Somuenzaniso, gastric urikanwi chinopinda rwatata.

dumbu kwevanhu rwakaramba uye simba tsandanyama muviri, ine asi kunzwisisa chivakwa. Cardiac, bottom, muviri uye pyloric dunhu - ndiwo mamiriro mudumbu. Cardiac Buri iri mumwoyo, ndiye pamusuo yegurokuro mudumbu. The pasi riri kumusoro riine yegurokuro. Gastric muviri ndicho chinhu chikuru chikamu chomuviri, iyo muganhu pasi ane wegedhi, uye kumusoro kusvikira pasi mudumbu. Wegedhi kana pyloric chikamu - iri mugero refu, kuguma unova nomukova duodenum.

The anatomical nemamiriro mudumbu rinoumbwa matatu akaturikidzana. Kubva panze kuti hydrate muviri obvolochen serous membrane. The pakati rukoko chinhu tsandanyama rukoko ine yokunze paiva longitudinal, nepakati dzeraundi makavharidzira, uye rwomukati oblique rukoko. The gobvu rukoko - ichi mucosa, izvo inoumba chikamu submucosa. Vose akaturikidzana mudumbu kuzadzisa chinangwa chaicho. Saka, serosa anoramba zvinowanisa emura kuderedza kukweshera pakati pezvitunha, asi tsandanyama rukoko chinopa injini kushanda mudumbu, uye gastric madzihwa rakafukidza rusvingo, anodzivirira kubva kukuvara.

The dumbu ane panzvimbo kujairika yakarongeka munyonga chimiro, asi hapana inokosha. The macroscopic nemamiriro mudumbu iri zvakakura-kura concavity, ndiro dzayo pamusoro pfungwa uye pasi muviri anonzi. rikawira zvokudya zvose muchikamu ichi mudumbu. Chete pashure iwe kunze zvikamu zvokudya pano, zvose zviri zvishoma nezvishoma kutamira kunzvimbo dzapasi chikamu mudumbu kusvikira ndichibvunza kugaya uye mbereko achishandisa gastric muto.

mana makuru mashandiro anoita mudumbu vangazivikanwa - nokugeda zvokudya, ayo mbereko, mapuroteni kugaya uye Absorção de Água shuga. Kukuya zvigadzirwa rinoitwa vaviri nemakemikari pezvakaitwa uye achishandisa tsandanyama kufamba (zvemaziso pezvakaitwa). Pashure zvokudya, zviri zvinoderedza mudumbu anobvumira kusanganisa, muchikuya, uye pakupedzisira, kufambisa zviri chikamu chiduku zviri ura duku. Zvisinei, kukosha, ndizvo chii anogadzirwa mudumbu uye ichi ndicho chinoratidza kusiyana kwayo. Zviri mudumbu yakavhenganiswa zvomudumbu makemikari uye gastric muto chikafu. The chikuru zvinoumba muto riri hydrochloric asidhi uye pepsin, uye zvibereko mumasero dzavo gastric. Hydrochloric asidhi ndiko kungatikanganisa kune tupukanana zvose uye utachiona, uye rinoshanda chete simba chaizvo asidhi runyararo. Rinovatadzisa ari Absorção de Água neshuga, inogadzirwa kubva pakutanga kuonana zvokudya pamwe nemate, nokuti acidic kwezvakatipoteredza anobvisa makemikari zviri kukonzera izvozvo. muvhenganiswa ichi chaiva muurayi (sezvinei chete nokuti utachiona) vari zvinobudirira anogadzirira zvokudya zvimwe kubudiswa muna duodenum.
