Small ura: tsananguro, mamiriro uye mashandiro

Sei kushamwaridzana nhete uye guru ura? Ndezvipi zviri dzaimirirwa zvikamu zvomudumbu turakiti? Chii basa duku ura unobatsira nedanho Absorção de Água muviri? Tichaedza kupindura izvi uye nemimwe mibvunzo pasi.

Part duku ura pamusoro munhu

Kusiyanisa bowel duku yakadai:

1. Duodenum chinobatanidza kuti nomudumbu rwakatsauka. Ichi kutanga duku ura anoumba munhu loop akapoteredza chidhongi rwatata. The duodenum iri zvinenge zvachose riri retroperitoneal mhango. Mhiri panogumira nzvimbo chete manda rayo duku - ampoule.
2. Jejunum anoumba repamusoro duku ura. Dzaitaurwa muchimiro zvishwe nomwe okurutivi parutivi peritoneum rworuboshwe.
3. Ileum yaiva yepazasi rworudyi nzvimbo mudumbu. Its kuguma loop inopfuura iri pelvic munharaunda. The ileum zvakabatana dzinza uye ari pedyo napedyo kuti dundira, muchibereko chemusikana (vakadzi).

mumuviri parameters

The pamusoro zvikamu ura duku migove siyana vane gogonera dhayamita. Muna indekisi distal mapazi ari 2-3 masendimita proximal kuna - 4-6. Pakukora ari intestinal rusvingo akaenzana 2-3 mm uye kunosvika 4,5 pana kuderedza tishu. Kureba duku ura rose kungava 5-6 metres. Panguva iyoyowo pakurema kwayo mune vakuru kwava 650

Small ura: madhipatimendi, mabasa,

Chikuru kugaya pezvakaitwa zviri kuitika zviri ura duku. The mucous Kamudzira yekwataigara zvinyama unobereka pakaitwa basa enzayemu. Ivo kupatsanurwa hummus - zvokudya nemuriwo akasikwa gastric facial. Pano kubatsira zvinhu zviri woga kupinda node uye ropa capillaries zvinopa chokufambisa kwavo nyama uye nenhengo dzawo. Funga mabasa anoitwa zvikamu ura diki:

• Duodenum - the hydrolysis kwemapurotini, makabhohaidhiretsi, mafuta. Rinotibatsira chinoshingaira kugadzirwa zvomudumbu makemikari. Kurongedza mashoko undigested zvokudya zvacho bile chokufambisa mudumbu mukati.
• Jejunum - injini, kubvisa, hormone basa, kuti hydrolysis pamusoro Polymers.
• Iliac nzvimbo - chokufambisa uye motokari chaitika. Inopa Absorção de Água pamusoro zvinhu izvo inoumbwa hydrolysis. Anochenesa bile acids.

Kukwanisa masero ari ura duku kuti kemikari kugadzirwa

Kugadzirwa mahormone anoita somunhu dzakananga kushanda zveko tishu. Part of ura duku havasi chete chikamu zvomudumbu turakiti, asi chezvibereko kwemakemikari anobudiswa hurongwa. It kunobereka yakafarikana pasi mahormone kuti waidzora chokufambisa uye gwenya basa ura uye mumatumbu.

Muna ura duku pfungwa inotevera akagadzirwa kwemakemikari anobudiswa masero:

• I-masero - kubereka cholecystokinin;
• D-masero - somatostatin;
• M-masero - motilin;
• G-masero - gastrin;
• K-masero - shuga-zvaanoda insulinotropic polypeptide;
• masero S- - secretin.

Unorema masero kemikari-zvibereko riri jejunum uye duodenum. Small chikamu kwavo - vari iliac.

Sei kugaya ari ura duku?

Kugaya ari ura diki sezvinotevera. Pre-zvakaipa mate uye gastric muto pulp ichibva mudumbu iri acidic. Muna ura duku gobvu anomiririrwa alkaline kurwisa. Saka Zvakanyanya Kunaka Panguva Yepamuviri ezvinhu kuti processing muviri makemikari. Cleavage of puroteni zvinoumba zvokudya slurry zvinokonzerwa zvinotevera zvinhu intestinal facial:

1. Makemikari enterokinase, kinazogen, trypsin kupatsanurwa nyore mapurotini.
2. Erepsin unodokwairira peptides kupinda amino acids.
3. Nuclease migove kuti kuronda mamorekuru dzakaoma mapuroteni mavambo, aizivikanwa nucleoproteins.
4. Makemikari maltase, phosphatase, amylase uye lactase kuputsa makabhohaidhiretsi.
5. Lipase vatendeuka kwemafuta.

Pashure kwetunhu zvinhu zvinokosha kubva chikafu pulp kubudikidza kurapwa pamwe makemikari, proteinaceous uye carbohydrate vomumatunhu vari yokuita zvinoitwa villi yacho ura duku. Uyezve zvisaririra zvinhu kuita pamusoro venous capillaries ari chiropa tishu. Uyewo, kuti mafuta vanotumirwa kune nhengo dzinobudisa hurongwa.

Zvirwere ura duku

Rakajairika nezvirwere chokuita duku ura, ndivo manyoka uye pachituru kunonoka anotenderera. Defecation Zvirwere kazhinji pamwe kukura kurwadziwa peritoneum. Kazhinji, kana nomuchetura uye zvirwere zviri ura duku pane zvakawanda flatulence. Panyaya iyi, kurwadziwa ipfupi, mwero uye haisi chikuru kunetseka.

A zvakafanana chiratidzo yezvikanganiso mubasa iri ura duku - kutinhira ari peritoneum, kunzwa atypical kufamba mudumbu. Kakawanda, zviratidzo izvi ndiwo mugumisiro zvakawanda gasi kurimwa kubva kudyiwa bhinzi, makabheji, mbatatisi, rye chingwa. runogonesa zvikuru Zviratidzo izvi zvinogona kuva usiku.

Kuti uwane migumisiro kuguma Kukundikana pagadzirwe makemikari uye kukamurwa chyme pamusoro micronutrients. Kana kugaya nokuda Absorção de Água kuti zvinhu zviri muropa uye node midziyo, hakuitiki zvakanaka, zvinogona kutungamirira uremu, vachinetesa pamusoro pfupa uye tsandanyama tishu. kazhinji nemigumisiro fufune ndiko kurasikirwa bvudzi, ganda rakaoma, pakuonekwa kuzvimba mu wamativi.

Pane zvinhu zvinokosha zvakawanda kuti tipedzisire kukura pathologies vari ura diki:

• Malabsorption - malabsorption nezvinovaka muviri.
• Maldigestion - pasi zvomudumbu basa.

Kana isu kutaura pamusoro rwakakwana unhu chikafu kubudiswa slurry, yakafanana mananara kuitika tikafunga yakaderera kwevari makemikari ari intestinal facial. Low chinovira kunogona vawana uye magene. Kazhinji zvokurwara ichi chirongwa protrude mugumisiro echirwere kuzvimba, kwemakemikari anobudiswa zvirwere, kuvhiya kupindira.

Diagnostics

Rokuongorora pave intestinal zvirwere, vanamazvikokota akarwawo nzira kuongorora kwakadaro:

• Kamudzira ongororo;
• SPL;
• colonoscopy;
• endoscopy;
• fibroscopy;
• radiography.

Maererano pachisara pane anopiwa mureza muitiro. Murwere rents chetsoka yokuenzanisira, ropa chinobviswa. The zvituru vakaedzwa kuvapo honye. Kudzidza ropa kufungwa kumhanya kufamba masero matsvuku eropa. Uyezve, kuita Diagnostics, izvo anobvumira rokuongorora chiropa uye thyroid shwanu.

mabatiro

Zvipatara zvainanga kudzorera mashandiro ari ura duku, kunosanganisira, pakutanga kwezvose, kubviswa runotikurudzira chirwere. Nokusava makemikari ari intestinal facial achitora kugadzirira ane pavo chakaita zvokugadzirwa Sevamiririri. Izvi uremu iri basa zvinoreva kuti parenteral kudya nyama. Sechikamu kuvapo ichangobva zveefa emulsion kwemafuta, amino acids, mapuroteni hydrolysates, kuramba shuga.

Kana zvinetso zvinokonzerwa intestinal dysbiosis, akarayira inorwisa mabhakitiriya. The yokupedzisira kungakonzera kukwana kana kwakakwana kuparadzwa kunobatsira kasvisto. Nokuda kwechikonzero ichi, mushure kurapwa murwere zvinoda kubvuma "Bifikol", "Lactobacterin" kana "kolibakterin" - chaivo zvinogadzirwa kuti vane pesvedzero inobatsira kudzorerwa intestinal biocenosis.

Kazhinji, varwere vanotambura zvinetso zviri ura duku, vakanzi kurapwa kuti chinokonzera chisimbiso mutsvina yadzo. Izvi zvinosanganisira zvinodhaka mukuru zviri calcium, bismuth. Kana paumbwe emura mutsvina yadzo kunokonzera kukwana adhesion mafuta acids, kugadzirisa dambudziko kunge akarwawo pakushandisa kusashanda kabhoni. Zvose pamusoro kunaka zviitiko zvinoda pre-kurapwa nachiremba. Kuunza duku ura chaiko, zvakakosha kurega kuzvida, nenguva chirwere uye zvakakwana pekuhwa- nda dzakabudirira mazvikokota kurapa.

In mhedziso

Saka isu akatarisa kuti pachahwo diki ura mapoka, nemamiriro raimiririra chikamu zvomudumbu turakiti. Sezvaunogona kuona, dzemo zvinyama dzinoshanda zvokudya kubudiswa, anotsemura kuva yoga zvicherwa. Small ura unobereka makemikari, mavhitaminzi, mahormone, vamiririri kuti tiwedzere masoja ushande. Panguva imwe chete panowanikwa kushayiwa mabhakitiriya kuti vanorarama pamasvingo aro anobatsira, nguva dzose kunoita kuti pave pathological ezvinhu.
