Ipheshana yesisu

Pheshana emathunjini siyingxenye ye isimiso sokugaya ukudla bungene lomuntu. Futhi-ke kuhlanganisa nezindlala ezikhiqiza izimfihlo ezidingekile uze uwaqede yenqubo ukugaya.

Pheshana emathunjini lide kakhulu (10 m) tube, okuyizinga elenza umthetho ezindaweni eziningi osontekile ku ngesimo izihibe. Kuqala ukuvula umlomo, ingquza kanye imikhawulo. Izingxenye abakha ipheshana wokugaya ukudla, ngokushelela ihlangana zibe munye nomunye. It esiswini, ngalo ingaphakathi ngomlomo, emphinjeni, pharynx, emathunjini amancane, ikholoni kanye ingemuva.

Inqubo yokuwela ukudla kanye ushintsho yayo chemical iqala umlomo. Kulapha ukuthi ukuba afuthwe ngesibulali ngamathe, baba imilutha ye.

ukudla Eminye imibengo ingena emphinjeni - tube ijamo okungajwayelekile okuyinto unciphise downwardly, futhi ekupheleni phambili ingxenye kancane isicaba. Phela, nge pharynx futhi zokuphefumula kwenzeka inqubo ngokuqondene ngalo osebenza ku umgudu wokuphefumula.

Kugwinyiwe yinhlama ukudla ingena emphinjeni - ungumthombo ongumngcingo, ezingaphezu kuka dvadtsatisantimetrovuyu tube. It uxhuma esiswini nomphimbo. peristalsis ngomphimbo kusiza bolus okwenziwa. Ngenxa yalokho, i-esebenzayo imisipha, kuthatha nje imizuzwana emihlanu uphendulela esiswini - engxenyeni okubanzi umsele alimentary. Kubantu abadala, lokhu umzimba has a ivolumu 1.5 amalitha kuya 2.5 amalitha, futhi amadoda ingaphezu uthando lwabesifazane. Esiswini esingenalutho akuyona enwetshiwe, kuba isimo ukusikwa. Bolus sabanjwa okuyingxenye layo elingenhla, odlulela odongeni umzimba kanye peristaltic, ezinyakazayo Translational Ukuthuthukela phansi. Phakathi kwalolu shintsho, it is afuthwe ngesibulali ijusi esiswini, okuyinto ezikhishwe nezindlala isisu ngaphambi kokudla (reflex) futhi ngokuxhumana ngqo nalo. Njalo isiqephu esisha odlulela ku kulowo odlule. Bolus ungaphakathi esiswini kusukela amahora amathathu kuya kweyishumi, isikhathi esanele ukuze ofakwe juice ethakwa by the nezindlala zomzimba.

Khona-ke ngokusebenzisa sphincter, okuyinto ngezikhathi livuliwe, ke iwela emathunjini amancane siyingxenye ende kunazo zonke i-canal alimentary - kuze kube amamitha ayisithupha. It siqukethe le jejunum, duodenum futhi ileum. Lapha uphela ukucutshungulwa ukudla bolus enzyme, zikwazi ukuthola izakhi, futhi ephukile phansi amaprotheni, ama-carbohydrate namafutha. Ngenxa ukunyakaza kwemisipha emathunjini amancane futhi kuba okuxubile isendleleni.

Esikhathini ikholoni abasasele izidakamizwa amanzi amuncwa. Iphinde kwakhiwa sezinyawo zinesisindo esiphansi, okuhlangene ukuwela ingemuva bese uphuma umsele bendunu. Kuyinto plexus emithambo yegazi, lapho kukhona ezivamile isifo gastro-emathunjini ipheshana, njengoba hemorrhoids.

Ngokuvamile, izimbangela zezifo wokugaya ukudla nhlobonhlobo. ukusatshalaliswa wabo encike ngqo kwi Izimo zempilo nenhlalo yezindawo nendawo yokuhlala ubudala, ubulili lesiguli, kwi Ukudla, okuyinto baye basungula ngokomlando.

Esinye sezizathu eziyinhloko - ijubane yesimanje yokuphila. Kuyaqapheleka ukuthi izakhamuzi zedolobha ngokuvamile uhlushwa nezifo zengqondo isisu namathumbu. Futhi bamatasa bathambekele kakhudlwana kunabanye yalabo abanhliziyo umsebenzi ezihlobene nokucindezeleka ngokomzwelo.

Eyesibili kuthonya ukuthuthukiswa izifo, ezithinta pheshana emathunjini, - ukwephulwa umbuso Izinga lokudla.

Ngaphezu kwalokho, ukuvuvukala pheshana emathunjini avuse helminthiasis futhi izifo ezithathelwanayo (ukusha kwesibindi, isifo sohudo, ukudla okunobuthi).

Kungakhathaliseki ukuthi iyini imbangela, ukwelashwa okufanele kufanele sigcwaliswe udokotela onguchwepheshe. Njengoba self ngokuvamile kuholela ukuba ngcono isimo, kodwa okubi kakhulu yayo. Ngemva reception eside kwemithi (kuhlanganise okuzenzela) ngaphandle kokubhekwa ngabezempilo, yisishiso okukhulu esiswini noma ikholoni izophela ku esigabeni ezingamahlalakhona. ingozi Omkhulu asathuthuka izilonda esiswini noma izilonda wokugaya ukudla ipheshana isikhunta (isibonelo, emva ukusetshenziswa isikhathi eside kwama-antibiotic).
