Emathunjini amancinci: bakhuphe konke ukutya

Kulapha ukuba umzimba siyakrazula yonke ukutya, kakuhle phantse yonke into. Apha kukho unyango ngononophelo kwaye ngabom chemical izondlo ezahlukeneyo. Kukho isonjululwe, uya ezifunyenwe xa kutyiwa. Ndiyaqonda ukuba le ndawo engaqhelekanga? Ewe, lo indima edlalwe yi emathunjini amancinci emzimbeni.

Emva acid kunye machining nesisu ukutya, ngelakamva ongena emathunjini amancinci. Kwaye iinkqubo ezikhoyo apha - ezingaqondakaliyo. Apha umzimba ngeendlela ezahlukeneyo, "uqhubeka" i izimbiwa igazi, amafutha, iivithamini, iicarbohydrate, kakade, nomatse. Ukuba umntu ogula kakhulu ngakwicala emathunjini amancinci, umzimba okunene ulambile lonke ixesha. Kulungile ukuba iSifo ezinjalo kungenzeki rhoqo kakhulu.

Le emathunjini amancinci ayikho elide kakhulu. Kwi-avareji, 6 kuphela mitha. Le ndawo iyonke ityhubhu ayikho mkhulu kangaka. Indlela ukuba umzimba, kuba apha kufuneka ufunde phantse yonke into? Imveliso - isakhiwo ekhethekileyo emathunjini amancinci: kumphezulu wayo - isixa elikhulu ngokwenene ezibayeni ezincinane, oko konyusa kakhulu ubuso ngokubanzi, nto leyo ibaluleke kakhulu kukufakwa izondlo (njengoko zizazinzulu izondlo ngokubanzi). Kodwa oku konke. Sekunjalo phezu engaphakathi emathunjini amancinci kakhulu villi. Kuwo - nkqu izakhiwo abangcono - microvilli. Xa villi na imithambo yegazi neeflaski nkovu, apho izondlo ezininzi kuza.

Iiseli olunga- phezu ngaphakathi apha naphaya ukuze sokufunxa iimolekyuli ukwahlula ukutya. Amafutha kweyela kwinkqubo emithanjeni, yonke into - egazini. Emva koko - esibindini, olawula ekudleni eswekile yegazi.

Thin kwesisu yabantu ayikho into esisigxina, isiphathele isakhiwo udonga maleko izihlunu, kodwa ngenxa yokuba rhoqo ihamba ngesingqi. Le nkqubo ibizwa ngokuba peristalsis. Ngokubanzi, kuba kade kakhulu. Xa oku kusenzeka (kunye nenkqubo efanayo kwamaza amancinci), ezi villi zicwangciswa intshukumo, nto leyo eyandisa inani zoqhagamshelwano kunye iimolekyuli ukutya. Phezu yethumbu babe engontsini ezikhethekileyo - le crypt, bevula iintlobo nemisinga unamadlala yokwetyisa. Zonke yethumbu - unengqiqo kakhulu kwaye kube yinkqubo nzima elilungelelanisiweyo. Kuye iindlela yalo mmiselo, umzekelo, izinto ezithile secreted yi kwindawo enye ukukhuthaza iindawo apho ukutya ukhwela.

Njengenxalenye emathunjini amancinci yahlulwe yangamacandelo amathathu: okokuqala, lo duodenum, yaye okwesibini, ezinqinileyo, okwesithathu, lo ileum. Ngoko nangoko emva kokuba isisu ukutya uba asidi kakhulu, nto leyo ibe ntle kwamanye amasebe, ezo nto lulungiselelwe ukuba lube Ph onjalo. Yintoni umzimba kule meko? Kakade ke, lo kwealkali kubalaselisa. Yiloo nto brunnerovy ndlala. Neutralization reaction kwenzeka - kwaye acid nesisu akuthethi izilonda apha emathunjini. Le jejunum Iinkqubo okunene zigqityiwe ukwetyisa, sinceda kolu donga enzymes.

Kutheni emathunjini amancinci kuthiwa kunjalo, yintoni na lo gama? Ingongoma ububanzi bayo, xa kuthelekiswa ikholoni ngayo 3-4 cm - umzobo ezindilisekileyo kakhulu. Ashinyeneyo amaxesha 3 ngokubanzi, kodwa ke eso sakhiwo kuvumela emathunjini amancinci ukuze baphumeze umsebenzi wabo singayekwa - ukufunxa izondlo. Kakade ekupheleni kwayo, ileum, iyeza Oku kwelifunekayo, kuphela inyongo abuyela nge igazi kwesibindi eludongeni kwamathumbu. Kwaye ke Amathumbu amakhulu nga 'imali' nasiphi na isixa - ukuze imunce amanzi kwanele.

Njengoko ubona, emathunjini amancinci - kuba igunya kunzima kakhulu amalungiselelo, nto leyo ebonisa impilo kakhulu ngqo. Ngapha koko, loo nto ixhomekeke kuthi ukuba womelele, smart kunye ezintle okanye hayi. Ngoko ke, simele sinikele ingqalelo impilo yabo namathumbu ngexesha lokuba aphathwe xa kuyimfuneko.
