Kwesisu ileum. Imisebenzi sifo, unyango

Iliac emathunjini (kwigama lesiLatini «ileum») imele icandelo esezantsi emathunjini amancinci. isiqalelo GI onjalo umsebenzi wayo kunye nesakhiwo. On kubo ungafunda ngaphantsi kancinci.

Ileum: phi?

Le ileum ibekwe kwi iliac fossa ekunene (okanye osesiswini) kwaye siyahlukana emathunjini iimfama usebenzisa bauginievoy apata, okanye ekuthiwa-valve ileocecal. Inxalenye encinane Umzimba uthatha epigastrium, ummandla yosana, kwakunye kwisisu zangasese.

isakhiwo

Kwesisu ileum namathumbu ezingcakacileyo iyafana kubume. Umaleko ewonke komzimba kukho isifo ukuba ngokugqithiseleyo wawutyabeka Imicu (ukunyuka malunga 1 nawethu). Ngenxa yoko, phezu kwezi ngongoma ubunjwe epithelium columnar. Xa iziko ise sinus emithanjeni, kwakunye emithanjeni (imithambo yegazi).

Kufuneka kuqatshelwe ukuba villi kwi ileum ethunjini kuba ngaphantsi kakhulu kunaleyo jejunum. Noko ke, bonke bathathe inxaxheba kwinkqubo yokufumana luncedo kunye nezondlo. Amafutha sebenzi yi ezityeni emithanjeni, kunye acid kunye monosaccharides - for lwemithambo. Lonke isifo le ileum unalo kumphezulu kunokuba rough. Oku kungenxa yobukho crypts kunye villi of pleats setyhula. data Ndiyila ukwandisa kakhulu kumphezulu yonke isifo isisu, nto leyo ngokungathandabuzekiyo kuchaphazela inkqubo ukufunxeka ukutya kwetyiswe.

Iimpawu ze isakhiwo ileum

villi ezinqinileyo ileum ayafana, imilo esifana amagqabi okanye iminwe. Kufuneka kuqatshelwe ukuba zifumaneka kuphela mithambo zamaqumrhu zikhankanywe ngasentla. Inani emathunjini villi kwi ileum ekungabonini kumaqhekeza-18 ukuya kuma-35 nganye 1 isikwere. mm. Ngelo xesha linye yokuba ukubhitya kancinane ngaphezu kwabo akhiwe duodenum.

crypts isisu, okanye ngokuba nobubovu liberkyunovy amele engontsini emvulophini, babe uhlobo ngemibhobho emincinci. Le isifo kunye submucosa le ileum ukwenza ndezela setyhula. Le epithelium kubo single-umaleko ibizivalele prismatic. Ngendlela, ukuba inwebu kwiinwebu umzimba submucosa yaso, emva ezo ijwabu kwezihlunu. ZifunwaEzokugqibela zidweliselwe zimelwe ngeengcamba 2 kwimicu ezigudileyo; langaphandle (okanye longitudinal) kunye nabantu abangaphakathi (okanye setyhula). Phakathi kwabo kwizicwili evakalala leyo eye imithambo yegazi nemithambo-dystrophy plexus ama. Ebubanzini kwale maleko kunciphisa ukuya inxalenye yesiphelo ye emathunjini amancinci. Kubalulekile ukuphawula ukuba umaleko dystrophy umzimba owenza umsebenzi wokuxuba nokudobelela chyme.

Iqokobhe engaphandle ye ikholoni iliac - serous. Igqumeke macala onke.

Eyona engundoqo Imisebenzi terminal ileum

lungu thaca owenza imisebenzi emininzi. Ezi ziquka oku kulandelayo:

• Ukuqhela enqanda;
• nokufunxwa izondlo, izimbiwa kunye neetyuwa zaso;
• ukwetyisa ukutya ezayo.

Iimpawu ze ileum

ayo isisu umzimba uqala ukwahlula phantsi kweempembelelo aphazamiseke chemical bokukhanda ezindongeni chyme. Kwisithuba seeyure ezingama-24 imveliso wayo ukufikelela 2.4 iilitha. Xa olu juice usabela obrak, yaye inxalenye yayo ashinyeneyo ibandakanya lunamahlwili amhlophe-epithelial iiseli, ukuvelisa lokwandisa enzyme. Xa iiseli ezifanelekileyo baqale kukhatywa kwi sayo isisu, uze ukujingxela, ngaloo ndlela kubonelelwa ukugaywa cavitary.

Kuyaphawuleka ukuba kumphezulu ngasinye iiseli microvilli epithelial. Zimele protuberances yantlandlolo, leyo ayinakutshintshwa enzymes. Enkosi kubo, kukho ngomnye umaleko kwinkqubo yokwetyisa, ebizwa ngokuba inwebu (Parietal). Kwesi sigaba kwi ileum kwenzeka haydrolisis kokutya kunye ukufunxeka kwayo.

Yinto eyaziwayo ukuba incindi wamathumbu iqulethe kanye 22 enzyme. Ifowuni enterokinase ephambili. Le enzyme ilungiselelwe ukusebenza trypsinogen pancreatic. Ukongeza, amathumbu ileum yabela juice, equlethe izinto ezifana lipase, amylase, sucrase, peptidase kunye phosphatase obrak.

Promotion of chyme kwezinye inxalenye iphecana wamathumbu kwenziwa ngokunciphisa umaleko kwezihlunu le imicu. iintlobo zazo ziphambili ze abakwazi kubizwa ngokuba peristaltic kunye pendulum. Iqela lesibini emanxebani kuvelisa ukuxuba chyme. Ke (peristaltic) amaza umbungu-like, zisenza ukutya distal.

Phela, zombini zimelwe uhlobo ukwetyisa ezikhoyo kunxibelelwano n'wina. Xa haydrolisis ingontsi kwezinto ezinzima ngakumbi a ebizwa ngokuba yi-intermediate. Le mveliso aphathwe iye zifunxe ngoncedo ndizayo ekugayeni. Ke iqala inkqubo nokufunxwa izondlo kunye neetyuwa. Oku kubangelwa kukwanda xi intracolonic kunye motility kwezihlunu kunye nentshukumo villi.

Zokwaphulwa kwemithetho zezifo ileum

Ileum (apho umzimba uchazwa ophezulu elincinane) idla phantsi kweenkqubo arhabaxa. Zonke izifo emathunjini amancinci ukuba babe iimpawu ezifanayo. Njengomgaqo, zisekelwe ukugxojwa wokugaya, excretory, kwaye umsebenzi sokufunxa motor. Ukuziqhelisa lwezonyango, ezi ezinxaxhileyo bagqiba ukuhlanganisa phantsi kwegama omnye - malabsorption syndrome.

iimpawu Common kwezifo

Ileum, apho sifo zenzeke ngenxa yezizathu ezahlukeneyo, phantse usoloko nefuthe iimpawu ngokubanzi lokubandezeleka. Ezi ziquka oku kulandelayo:

• syndromes buhlungu;
• intlungu esitulweni;
• ukuduma ethunjini;
• flatulence.

Kaninzi, izigulane isikhalazo oogqirha babo baye urhudo oluhlala elide nohambo kwindlu yangasese izihlandlo 4-7 ngosuku. Kulo ukutya undigested inokufumaneka endleni. Ngentsasa elandelayo, umguli kudla uziva ngokuxokozela apha emathunjini, nto leyo ngokuqhelekileyo kudambe kuphela ngokuhlwa.

Of nachaphazelekayo emathunjini iliac maxa wambi kubangela intlungu. Basenokuba indawo ezahlukeneyo (kummandla yosana, ilungelo osembindini ka esisu kunye phantsi "icephe") kunye nomlinganiswa (eziqukayo, ekhathazayo nangokukhalaza). Ngokuqhelekileyo, ubunzulu intlungu kakhulu lehlile emva wokuqhuba iigesi kwakhiwa.

iimpawu zangaphandle zezifo ileum

isifo wamathumbu abancinane ikhatshwe leli sebe kunye kubonakaliswa extraintestinal. Kokuba babe balindeleke ukuba malabsorption kunye ukwetyisa kweezondlo, iivithamini kunye neeminerali. Kulo mzekelo, izigulane ngokukhawuleza ngokwaneleyo ukuba unciphise umzimba kwaye awuzukuphila. Ukuswela iivithamini B kunye nentsimbi kukhokelela kuphuhliso kwegazi, ukuyilwa neentanda imilebe kunye neekona komtshiso emlonyeni. Noko ke, ukuba, umzimba uqalisa abaswele iVitamin A, kungabonakala ngokwayo kwi kome le conjunctiva nasebusuku ziimfama. Ukuba umzimba lo yesigulane ukopha, ngoko oku kubonisa ukuswela vitamin K.

isifo Crohn kaThixo

Esi sifo kakhulu kwaye ngokufanayo emathunjini amancinci izifo Crohn ngayo (okanye ekuthiwa- terminal ileitis). Ngokwesiqhelo ezinjalo ukudumba uphethwe eyendayo kule ngeesentimitha yokugqibela 15-20 le ileum. Ayifane kule nkqubo ibandakanya GI imfama, ubukhulu kunye duodenal.

Ukudumba ileum, iimpawu apho siza kuqwalasela ngezantsi, kufuneka ziphathwe kwexesha. Kungenjalo, kwiminyaka 3-4 isigulane ingaqala ezinobuzaza ezifana emathunjini, fistulas, amathumba, peritonitis, amyloidosis, ukopha kunye nabanye.

Iimpawu zesifo Crohn kaThixo

Iimpawu zesi sifo zahlukile.

• ubuhlungu obukhulu kwisahlulo esisekunene (badla embhoxo ekliniki of appendicitis ahlekise). Kulo mzekelo, icesina yomguli endibulala isicaphucaphu rhoqo kunye nokugabha. Ngokuqhelekileyo intlungu kwenzeka emva kweeyure 3-5 emva kokutya.
• Igazi kunye emaciation.
• Loloyiko le ileum, obe ubaqhiphukisa emathunjini.
• nokuqunjelwa Chronic okanye ukurhuda kwaye ukuduma ethunjini.
• ukopha zeemvula okanye admixture omncinane wegazi kwi isitulo

nezinye izifo

hyperplasia Lymphoid kwesitishi ileum lwenzeka kwi imvelaphi immunodeficiency kunye notshintsho proliferative eludongeni emathunjini. Ngokuqhelekileyo, ezi nguqu basoloko zezomzuzwana kwaye shwaka ngaphandle, azafunyanelwa ndawo ngokwabo. Isizathu sale kutenxa ukuze benze impendulo ukungabaniki nakwa KwaZulu-ezinxulumene lymphoid izihlunu, olwenzeka phezu ezenzeka ngaphandle.

Iimpawu ze hyperplasia lymphoid

Iimpawu kufuneka ibandakanye, ezifana:

• sorhudo;
• walunywa;
• admixture igazi kunye yencindi kwi isitulo;
• flatulence kunye ukuqumba;
• komzimba;
• kunciphise ukuxhathisa umzimba ukuba ungenwe lula zizifo ezahlukahlukeneyo.

Ekubeni hyperplasia owomeleleyo ukuphuhlisa iimpawu emathunjini. Phakathi kwezinye izinto, ukuba izifo yethumbu ekunokuthiwa enteritis kunye nomhlaza.

Uxilongo kwezifo kunye kubanga

Ukudumba ileum axilonge ukubonakala kwazo kwimeko yomguli emva iimvavanyo zegazi, umchamo kunye ngendle, kwakunye ngoncedo le ndlela namhlanje yokuhlolwa endoscopy fiberoptic. Kulo mzekelo, izigulane badla utshintsho ezichongiweyo submucosal inwebu emathunjini. ukungaqheleki ezinjalo non-ngqo basenokuba kwi imvelaphi polyposis ehlasela, tonsils ezingapheliyo kunye nokuphazamiseka olusebenzayo ikholoni.

unyango lwezifo

Ngokuqhelekileyo hyperplasia limfofollikulyarnaya kuchaphazela kuphela terminal ileum. Esi sifo iimeko ezinxulumene, yaye ngoko ke ayithethi kufuna unyango. Njengokuba isifo Crohn kaThixo, umhlaza kunye nezinye iinkqubo ukudumba, ngoko ke unyango kunyuswe, ezichaphazela iphecana zesisu lonke ekugqibeleni kukhokelela ekufeni. Kulo mzekelo, unyango kukusetyenziswa amayeza, kuquka nemithi, unikwe kuphela gastroenterologist onamava. Hi ndlela leyi, izifo rhoqo ezifana kwi zigaba kamva yenkqubela aphathwe ngendlela uqhaqho.

Kufuneka kuqatshelwe ukuba ukongeza amayeza ekunyangeni izifo kwisebe emathunjini iliac amancinci amiselweyo kunye ukutya engqongqo. Njengomthetho jikelele, oko kuquka kuphela imiphunga, ngokukhawuleza ukutya kunye aneevithamini ukutya. Ukongeza, isigulana Akuvunyelwe ngokungqongqo ukuba ukusela utywala, ngamandla ezinetyuwa, okuneziqholo, okunamafutha, okroqiweyo, nomnikelo enzima, intlanzi, mushroom izitya. yokudla Isigulana kufuneka iquke ipapa efudumeleyo, esojiwe polumoloke, izolo imveliso isonka sengqolowa emhlophe, ngamanye amaxesha ibhotolo, begilana amaqanda, iti, iziselo iziqhamo, iziselo iziqhamo, iinyonga umhluzi, iiblueberries, cherry zasendle. Ukuba nokudla uthathe onke amayeza amiselwe ngugqirha, ngenxa yonyango ukudumba ileum ngokuyimfuneko uya kusinda.
