Emathunjini amancane: athathe zonke ukudla

Kulapha umzimba kuthatha kusuka ukudla konke, kahle cishe konke. Lapha kukhona ngokucophelela futhi ngamabomu ukwelashwa kwamakhemikhali izakhamzimba ezihlukahlukene. Kukhona isixazululekile, uzobe atholwe uma kudliwa. Ngicabanga ukuthi le ndawo kuyinto engavamile? Yebo, lokhu indima eyadlalwa emathunjini amancane emzimbeni.

Ngemva esiswini acid machining ukudla, lona wamuva engena emathunjini amancane. Futhi izinqubo ezenzeka lapha - ezicashile. Lapha umzimba ngezindlela ezahlukene, "inomqondo" amaminerali igazi, amafutha, amavithamini, ama-carbohydrate, futhi-ke, izingwejeje. Uma umuntu ogula kakhulu phezu ingxenye emathunjini amancane, umzimba empeleni ulambile. Kuyinto enhle ukuthi izifo ezifana azisenzeki kaningi impela.

Ithumbu elincane akuyona eside. Ngokwesilinganiso, amamitha 6 kuphela. Le ndawo Imininingwane tube akuyona omkhulu kangaka. Kanjani ukuba umzimba, ngoba lapha udinga ukufunda cishe yonke into? Lokukhipha - isakhiwo ekhethekile emathunjini amancane: ku ubuso bayo - a omkhulu ngempela emphethweni ngesibonakhulu, ke kakhulu kwandisa ebusweni jikelele, okuyinto ebaluleke for ukumuncwa kwezakhi (ososayensi abayibiza ngokuthi izakhi ngokuvamile). Kodwa akupheleli lapho. Namanje phezu engaphakathi emathunjini amancane kukhona villi. Futhi kubo - ngisho izakhiwo zikanokusho - microvilli. Esikhathini villi has imithambo yegazi nemithambo ye-lymph flasks, lapho izakhi eziningi beze.

Amaseli abami ebusweni kwangaphakathi bazivumelanisa ukuncela molecule ukudla zahlukana. Amafutha awela uhlelo lymph, lonke daba - egazini. Khona - esibindini, elawula ukudla ushukela egazini.

Izacile esiswini womuntu awuyona into engashintshi, it has a isakhiwo odongeni kwemisipha ungqimba, kodwa ngoba njalo iqhubekela atishaye. Le nqubo ibizwa ngokuthi peristalsis. Ngokuvamile, kuba kancanekancane. Uma lokhu kwenzeka (futhi inqubo efanayo ku amagagasi amancane), i-villi asethwe iragela phambili, okuyinto kwandisa isibalo ukuxhumana molecule ukudla. Uma uyikha phezulu le emathunjini sibe kude ekhethekile - le Crypt, bevula ezihlukahlukene ukusakaza encane ka nezindlala wokugaya ukudla. Zonke emathunjini - kuyinto eliphusile futhi kuba uhlelo nzima ehlelekile. It has izindlela ayo wesi, isibonelo, izinto ezithile ethakwa ngomunye endaweni sikhuthaze izindawo lapho ukudla wakhwela.

Njengengxenye emathunjini amancane ihlukaniswe izigaba ezintathu zokuqala, le duodenum, futhi okwesibili, eziyisikhombisa ezimathambo futhi, okwesithathu, le ileum. Ngokushesha ngemva esiswini ukudla kuba azibukhali kakhulu, okungaba ezingezinhle ngenxa neminye iminyango, ezingalotshwanga bazivumelanisa PH ezinjalo. Yini umzimba kulesi simo? Yiqiniso, i-alikhali gqamisa. Yilokho brunnerovy indlala. Neutralization ukuphendula senzeka - kanye acid esiswini akakubangeli izilonda emathunjini. I jejunum izinqubo empeleni igcwaliswe ukugaya, ekusizeni kulokhu odongeni enzyme.

Kungani emathunjini amancane ibizwa ngokuthi kunjalo, liyini igama? Iphuzu ububanzi bayo, njengoba kuqhathaniswa ne ikholoni ke 3-4 cm - sibalo nesizotha kakhulu. Ukuqina izikhathi 3 ebanzi, kodwa isakhiwo esinjalo ivumela emathunjini amancane ukuze akwazi ukufeza umsebenzi wabo obucayi - ukuba zikwazi ukuthola izakhi. Kakade ekupheleni kwalo, ileum, izidakamizwa is cishe hhayi ugxile, kuphela Bile kancane wabuya nge igazi kwesibindi ogangeni wamathumbu. Futhi emathunjini ezinkulu kungaba "ukukhokhela" yisiphi isamba - ukumunca amanzi kwanele.

Njengoba ubona, emathunjini amancane - ke igunya nzima kakhulu ahlelwe, ebheka impilo eqondile kakhulu. Phela, kuncike ngokusikhuthaza ukuba siqine, smart futhi enhle noma cha. Ngakho-ke, kumelwe unake impilo yabo futhi wamathumbu ngesikhathi aphathwe uma kunesidingo.
