Amachibi ohlelweni womuntu wokugaya ukudla

Kwezokwelapha, kukhona amagama amaningi abstruse, engesiyo kulula ukukuqonda, futhi umzimba womuntu - kunjalo isimiso esiyinkimbinkimbi iziphathimandla ngenjongo abanye abaningi babe nombono ofiphele kakhulu. Kodwa-ke akudingekile ukuba usosayensi rocket, ukuqagela ukuthi yini umsebenzi wenziwa yizinhlaka wokugaya ukudla komuntu. Lokhu likhuluma ngokucacile igama labo.

Ngokwazi siyazi, umzila - elikhulu kahle emgwaqweni; ipheshana wokugaya ukudla, eyaziwa nangokuthi i-emathunjini, kuyinto kakhulu endleleni lapho ukudla Kufanele udliwe ngaphakathi umuntu. Nokho, incazelo enjalo, yebo, lolumalula khulu, into lifana incazelo ebonisa ikhanda umsebenzi: "Mina akudle." Kodwa ukuhlolisisa eningiliziwe Ukwakheka kohlelo nemisebenzi abamelwe lokho elikushoyo kusisiza ukuba siqonde kangcono ukuthi inqubo wokugaya ukudla futhi nohlobo lodlame ukuthi kubangela iziyaluyalu umzimba kanye nezifo ezihlukahlukene.

Ngakho, lokho okuyingxenye kwezitho kohlelo womuntu wokugaya ukudla?

Eyokuqala - iyona ngalo ingaphakathi ngomlomo lapho ukudla echayeke machining kokuqala kude kangaka nje. Siza e hhayi kuphela amazinyo nolimi, kodwa futhi nezindlala salivary, ngoba enzyme eziqukethwe ngamathe kakade ninamathele izakhi ezithile.

Ngokulandelayo, ukudla ingena emphinjeni, kodwa hhayi ngqo, kodwa ngokusebenzisa pharynx, okuyinto ngendlela reflex kusiza ukugwinya kakade imibengo futhi eqoqwe in a ukudla inhlama. Ngokwakhe emphinjeni kuyinto ngqo tube ubude 30 amasentimitha. umsebenzi wakhe - ukuletha ngokushesha ukudla esiswini, okusiza imisipha futhi abami ezindongeni epithelium squamous.

Uma izitho kwabantu wokugaya ukudla uhlelo ukuzama ukuhlela ngokulandelana usayizi, esiswini kungenzeka kube yinto esemqoka. Kulesi "isikhwama" iza ukugaya ngaphansi kwethonya juice esiswini. izingxenye zalo oyinhloko kukhona hydrochloric acid, bicarbonates, pepsin noma ezinye enzyme. Ezintathu zamatshe imisipha bushelelezi ukushintshanisa bolus ngaphakathi esiswini, usheshisa ukucubungula.

Nokho, akubona bonke kugaywe esiswini - "baton" engenela emathunjini. Noma obuntu ipheshana yesisu - endleleni, amathumbu - esigabeni elide kakhulu kuso. Kwayo ngokuphelele obuphelele kuze kube ngamamitha ayishumi, futhi uvumelane ke lapho esiswini, njengoba lisasesimweni kubhidlika, ezifana-moya noma frill. The main okuyingxenye - emathunjini amancane, kodwa noma kunjalo iyona duodenum, okuyinto zihlobene Amapayipi amanyikwe ama-enzyme ukuthi sokudiliza amafutha, amaphrotheni kanye carbohydrate, futhi gallbladder, equkethe elakhiwe isibindi Bile, futhi abahilelekile jikelele. Ulwelwesi lwamafinyila we encane ifomu amathumbu villi eminingi ukuthi kancane kancane ukuhambisa ngokududula eduze bolus onguthelawayeka, lezo kakade okwase uhlukanise zibe amangqamuzana izakhi. Through the villi kwenzeka ukumuncwa bangene igazi lymph.

Ingxenye yokugcina pheshana emathunjini - emathunjini ezinkulu. main Umsebenzi wayo - eqhekeza fibre esebenzisa amagciwane olukhethekile ukumuncwa uketshezi ekuqongeleleni izinsalela undigested zazo akhiwa sezinyawo ngokusebenzisa ingemuva kanye excreted ngaphandle. Kokuqala division emathunjini ezinkulu okuthiwa ama-cecum, kusuka lapho neseleko encane, mhlawumbe isitho womuntu kuphela ayinayo ezinye umsebenzi walo ewusizo - isithasiselo saleli Bhayibheli.

Njengoba ubona, umuntu wokugaya ukudla uhlelo zitho lula njengoba ungase ucabange. Lolu hlelo eziyinkimbinkimbi uchayeke ubuthi by ukungenisa imikhiqizo yakhe endala noma izinto empeleni ezinobuthi ke BATSHALE: i izimuncagazi kwenzeke iziyaluyalu umzimba kanye nezinye izinkinga, eziningi zazo sahlela emgudwini wakho emathunjini ngokwabo uma edla enyantisayo noma okubi betel ukudla . Futhi uma iningi kanzima ukusebenza emzimbeni yethu ithatha izintambo, kufanele okungenani ungagxambukeli naye.
