Small ura ... aripiko dzakaonda - ipapo uye kukuvara?

Kutaura chokwadi, pasinei zita raro, ichi reDare zvomudumbu hurongwa hwakasimba zvakakwana. Saka shoko rokuti "Putsira" rinogona kureva, asi, kuzotadzira chirongwa - kwete mumuviri, uye dzichipfekeka. Asi ura kavo pachena kuti kanenge dzimwe nhengo, uye sei zvimwe, kana tinogara vakaremerwa basa rake, kakawanda pamwero mukuru zvinonzi kudziviswa.

Panzira, kuti ura duku haisi dzisinganyatsooneki saka - kubva 3.75 kusvika 5 masendimita ari dhayamita, chete nokuti akanzi "musiyano" pamwe huru ura. Anomiririra kumicheto anenge 7.5 metres urefu, izvo akawanda zvishwe "akapeta" munzvimbo abdominal mhango. Asi nemamiriro ura duku haagarimo chete chubhu mumwe - pane zvikamu zvitatu: asi duodenum, diki ura uye ileum. Mumwe - yavo chinangwa.

Saka, pashure kubudiswa mudumbu chyme dzepanguva netsika anopinda diki ura. Uye ichi zvinoitwa zvishoma nezvishoma anodzidziswa. The simba peristaltic chinozunguzirwa kunoratidza zvakasimba nokukiya ruoko - munhu werudzii kurova-rova panguva nzira yokubudisa mudumbu. Izvi chendangariro yunifomu chokubuda. Saka chikamu nemuriwo 'kukandwa "pakutanga pamusoro ura duku - the duodenum. Kunyange zvazvo ndiyo chikamu - masendimita 25-30 chete - asi ichi ndicho apo pfungwa yokushanda inokosha zvomudumbu kwendangariro. Zvokudya rakaitirwa mudumbu kubudiswa, zvikuru hwakakanyiwa gastric muto, iyo asidhi nokungwarira akanga neutralized pedyo makemikari yakabereka rusvingo duodenal, uyewo avo kuti vanopiwa kubva pano rwatata. The pamuShuramiti akasuma nenduru dundira, ine pachake musuo waro pano - inoenda kuburikidza chiropa chigadzirwa - bile kunobatsira kugaya mafuta. Musanganiswa intestinal muto pamwe bile uye pancreatic unodokwairira zvidimbu zvokudya zvacho zvakadaro miniti, iyo zvino achava pasina dambudziko woga nomuviri kuburikidza intestinal madziro.

In iri jejunum, ane kureba anenge 3.5 metres, muitiro anoenderera was makemikari. Masvingo dhipatimendi ichi, uyewo ari ileum, akashongedzerwa nemamiriyoni villi duku, kuburikidza zviri wefodya unopinda muropa muviri. Ileum navo anowana kare zvishoma - kadhi iri "akashumira" kuti muviri calcium, vamwe mamineral mavhitamini, bile zvinoriumba, uye mvura. Uye panguva mbudo, achipfuura ileocecal munharaunda gwara, undigested zvokudya wakapfuurira huru ura.

Munguva duku ura nezvezvikwata zviviri anodudzira anoramba kunoitika - pendular uye peristaltic - vachifambira zvokudya panguva neavhareji yevanhu 2 cm paminiti. Basa iri ndiro dzakananga ruzha kuti yatinoti "mudumbu kutinhira." Motor kukundikana, pamwe siyana dyspepsia (vasingadzoreki romuzvarirwo basa) dzinongova rakajairika zvirwere aisanganwa ura duku. Kazhinji pamwechete dumbu kana guru ura zvinovhiringidzika, iye gastoenteritami, enterocolitis uye gastroehnterokolitah. Anogumbura pezvakaitwa muchikamu ichi zvomudumbu turakiti zvinetso kuguma secretory uye gwenya kushanda "mubereki" madhipatimendi, metabolic uye kweropa, neutachiona uye kunyange kujairika okunze migumisiro.

Zviratidzo intestinal chirwere - zviri kunyanya ratinoti abdominal marwadzo (kazhinji, izvi benzi guvhu marwadzo), manzwiro neshungu, kana kuridza-kutinhira. Chiri dzinoratidzwa nomusoro uye mukuru muutera, kurasikirwa kudya uye uremu, anogona kunomboitika huta zvirwere.

Yeuka kuti kazhinji kutungamirira chepfu bowel zvirwere zvinokonzerwa mishonga, zvinodhaka uye substandard zvigadzirwa, uyewo zvirwere zvokudya. Saka, zvakanakisisa kudzivirira ndiwo musoro kutaura kuti kudya, kubviswa fodya uye doro, uye supplementation pamusoro Mishonga zvokuwedzera uye mavhitaminzi.
