Iyini ukubaluleka kwesistimu yokugaya: izimpendulo ezibalulekile

Ekuphileni kwansuku zonke, abantu abavame ukulalela isimiso sokugaya ukudla, ukungazinaki izibonakaliso zomzimba wabo kuphela, kodwa futhi nokucabanga, ngaphandle kokuzama ukuthola ukuthi inani le-digestive system liyiphi inhlalakahle. Inani elinganele noma ngokweqile lokudla, kanye nokubunjwa kwalo, konke lokhu kuthinta enye yezinhlelo ezibaluleke kakhulu emzimbeni womuntu.

Ukugaya kuqala emlonyeni

Ukuzama ukuchaza ukuthi ukubaluleka kwesimiso sokugaya umzimba kungakanani, kufanele kufinyelele ngokushesha ukuthi inqubo yokugaya iqala ngokushesha uma iqebelengwane lekhekhe noma ama-Brussels ehluma emlonyeni womuntu. Inqwaba yezinhlayiya ezigcwala iminyene isendaweni yomlomo. Yimali evikela umkhombandlela wamazinyo, kuqinisekiswe ukuhambisana kwayo. Ngaphezu kwalokho, ngokugeza yonke indawo, amathe abiza ukungenwa yisifo sofuba, ngokuba yisifo sokulwa nemvelo, nakuba singenamandla. Ezingqungqutheleni ze-salivary inani elincane le-calcium likhiqizwa, elinika ama-coil koqweqwe lwamazinyo.

Nakhu kuyadingeka ukuthi umuthi uphuthukiswe kuphela emini, okusho ukuthi ebusuku amabhaktheriya angakhula abantu bawo. Yingakho ukuhlanza amazinyo kubaluleke kakhulu - kusihlwa nakusasa.

I-esophagus ne-tube emathunjini

Ukudla okufakiwe, ukuvutshelwa nokugaya okuvele sekuqalile emgodini womlomo, ngemuva kokuthi ukungena kungena kulesi sigameko. Ububanzi bale tube bubungamamitha amabili.

Ukusuka ku-esophagus lump food is in the stomach, enesimo esifisayo sesigxobo esinama-oblique. Itholakala nge-diagonally ukusuka kwesobunxele kuya kwesokudla, ngenkathi uhlangothi lwesobunxele luphakeme kakhulu kunelungelo.

Ngokushesha ngemva kokuba isisu siqala amathumbu amancane, kulesi sifo esitholakala emgodini wesisu. Ubude beli sakhi bufinyelela kumamitha ayisikhombisa. Kusemathunjini amancane ukuthi into ebaluleke kakhulu eyenzekayo - ukufana kwazo zonke izinto eziwusizo umuntu azibamba. Ngaphezu kokuphakama kwalo okumangalisayo, kunendawo enkulu. Phela, yonke imitha yemathumbu ihlanganiswe ne-villi encane, lapho ukushintshaniswa kwezinto kwenzeka khona. Uma zonke lezi villi ziqondiswa, khona-ke amathumbu azokhula ngobude izikhathi ezimbili nengxenye. Kusuka emathunjini ukuthi izakhi zifaka igazi, ngoba yonke i-villus iqukethe isitsha segazi. Lokhu kusisondeza ekuqondeni ukuthi ukubaluleka kwesistimu yokugaya kuyinto.

I-Biology: Ibanga 6

I-intestine engenhla iyinyumba, kuyilapho esiswini nasezingxenyeni eziphansi zamathumbu amakhulu inamba enkulu yezinhlobo ezahlukene zebhaktheriya ezisiza ukugaya. Isayensi yanamuhla iqinisekile ukuthi iningi le-immune system ligxile esiswini kanti isimo se-microflora sithinta kakhulu impilo yomuntu.

Mhlawumbe ngisho nomfundi kufanele azi impendulo yombuzo esikucabangayo kulesi sihloko. Okuthi: "Iyini inani lenqubo yokugaya ukudla?" (Ibanga 6). Umlingisi wesithupha kufanele abe nomqondo wesakhiwo saso, futhi nokuthi lesi simiso sigcwele ukuphela kwezinzwa, izigulane zivimbela ama-enzyme namahomoni, okunye okubalulekile empilweni.

Iyini ukubaluleka kwesistimu yokugaya ukudla?

Impendulo emfushane yalo mbuzo ingaba kanje. Ingxenye ebalulekile yesimiso sokugaya ukudla yizinyunyana ezihlala kuyo ezindaweni ezithile. Bakhuthaza ukugaya, ukugaya kanye nokwenziwa kwamaminerali, amaprotheni nama-carbohydrate. Futhi abanye baze bakhiqize amavithamini. Ngakho-ke, umsebenzi oyinhloko walesi simiso yi-cleavage nokugaya izakhi.

Mhlawumbe ukuqonda ukuthi ukubaluleka kwesimiso sokugaya ukudla kuyini, kuzofaka isandla esimweni sokukhathalela ngokwengeziwe kuye, kumnakekela, futhi kukusiza ukuthi ushintshe imikhuba yokudla ngokuyeka ukulimaza nokulandela okuwusizo.
