Wokugaya

Eli phecana zesisu yinxalenye yenkqubo zokwetyisa komntu. Kwakhona oko kuquka amadlala ezivelisa iimfihlelo eziyimfuneko kwikhosi epheleleyo inkqubo ekugayeni.

Eli phecana zesisu mde kakhulu (10 m) ityhubhu, nto leyo kwiindawo ezininzi ijijekileyo kulo uhlobo kweziporo zikaloliwe. Iqala ukuvula umlomo, ilindle kunye iphela. Iinxalenye ukwenza i wokugaya, kakuhle bahlanganisane ukuze omnye komnye. It isisu, kwisisu ngomlomo, kuvuleke iminxunya, pharynx, emathunjini amancinci, ikholoni kunye isikali.

Inkqubo yokuwela ukutya kunye lutshintsho ngemichiza iqala emlonyeni. Kulapha ukuba buzane ngamathe, etshisa.

okunye ukutya elinqunqiweyo ngokushiyanayo engena umqala - ityhubhu semilo engagunyaziswanga leyo uncipha downwardly, kwaye ekupheleni inxalenye ephambili atshabalalisa kancinane. Koko, nge pharynx kunye zemiphunga kwenzeka inkqubo ngokunxulumene apho sisebenza isixokelelwano sokuphefumla.

Uginye ngentlama ukutya engena kuvuleke iminxunya - indawo emxinwa, ngaphezu dvadtsatisantimetrovuyu ityhubhu. Idibanisa esiswini nomqala. peristalsis esophageal kunceda bolus move on. Ngenxa yoko, le imisipha esebenzayo, kuthatha kuphela imizuzwana emihlanu ejika isisu - inxalenye ebanzi lomsele alimentary. Xa abadala, le Umzimba umthamo neelitha 1.5 ukuya kwezingama-2.5, yaye Kubantu ngaphezu koko ngabafazi. Ngenxa yokungabi akukho sandisiwe, oko kwimo ukusikwa. Bolus ebanjwe inxalenye yayo ephezulu, utyhala udonga umzimba kunye peristaltic, eshukumayo translational inkqubela ukuya ezantsi. Ngexesha le nqubo, oko buzane incindi esiswini, nto leyo ekhutshwa ngamadlala esiswini phambi kokuba ityiwe (reflex) kwaye zidibane ngqo nayo. Wonke sifakiweyo, sitsha ngokutyhala ezidlulileyo. Bolus ukho esiswini iiyure ezintathu ukuya ezilishumi, ixesha elaneleyo kangangokuba nowento isiselo secreted yi amadlala zomzimba.

Emva koko ngokusebenzisa sphincter, nto leyo ngamaxesha kuvulwa, iwela le emathunjini amancinci na icandelo mde lomsele alimentary - ukuya kutsho kwiimitha ezintandathu. Luquka ezi jejunum, duodenum kunye ileum. Apha iphela processing enqanda bolus ukutya, ukufunxa izondlo, kunye neeproteni, carbohydrate kunye namafutha baphuke phantsi. Ngenxa iintshukumo izihlunu emathunjini amancinci kwaye bedidekile indlela yayo.

Xa ikholoni usasale kweziyobisi amanzi ithathe. Kwakhona bakha ubunzima isitulo, apho iwele isikali uphume emjelweni ezimpundu. Kuyinto plexus lwemithambo, apho kukho eqhelekileyo esigulisa gastro-wamathumbu phecana, njengoko hemorrhoids.

Ngokubanzi, izinto ezibangela izifo kwinkqubo yokwetyisa kuhluka. usasazo ixhomekeke ngqo kwi iimeko zentlalo indawo awayehlala yomguli ubudala, isini, phezu ukutya, ezithe zabakho ngokwembali.

Esinye sezizathu eziphambili - isantya mihla ubomi. Kuyaphawuleka ukuba abahlali besixeko badla ubunzima ukusuka nezifo ze esiswini kunye amathumbu. Kwakhona, ukuba usesichengeni abo umsebenzi ezinxulumene noxinezeleko ngokweemvakalelo.

Izinto yesibini eziphembelela uphuhliso izifo, nto leyo echaphazela iphecana zesisu, - waphula olawulo kunye nomgangatho ukutya.

Ukongeza, ukudumba iphecana zesisu bandiqumbise helminthiasis kunye nezifo ezosulelayo (hepatitis, segazi, ityhefu ukutya).

Enoba siyintoni na isizathu, unyango olufanelekileyo kufuneka kwenziwa ugqirha yobungcali. Ekubeni self kukhokelela ukuba ukuphucula le meko, kodwa okubi yayo. Emva ukwamkelwa elide amayeza (kubandakanywa ekhaya) ngaphandle kweliso zonyango, nangokurhala nokoyika esiswini okanye colon zinokudluliselwa kungena nqanaba ezigulo ezondeleyo. engozini enkulu yokuba izilonda esiswini okanye ukwenzakala ze iphecana fungi wokudla (umzekelo, emva ukusetyenziswa elide antibiotics).
