Wokugaya Human ukudla. Ubume kwamathumbu

isakhiwo wamathumbu iquka izabelo ezingcakacileyo nepeni. isebe Thin asuka ngqo emva isisu. Xa abadala, ubude malunga amahlanu eemitha. Ubume eqhelekileyo eli sebe akuthethi kuthi ubukho naziphi na iintsholongwane eziyingozi okanye yingenelo. Phantsi kweemeko ezininzi ezibangela ukuphazamiseka enzyme lwenzeka ngoLwesithathu afanelekileyo yokuvelisa eziphilayo kuwo. iintsholongwane izifo athwale usulelo, nto leyo sikhatshwa sorhudo kakhulu, ukuqumba, ukuduma, iintlungu inkaba. iintsholongwane Non-yayintsholongwane eyosulela kubangela ubuhlungu kunye Ukudumba apha esiswini.

Amathumbu amakhulu i phambili emathunjini amancinci. Umda lisebenza uxakaxa umatshini therebetween. Oku kuthintela ukungena okubhalwe ezincinane kunye nekhadi namanqatha aphinda icandelo obhityileyo. inkqubo (kwisihlomelo) ifumaneka kule caba.

Ubume emathunjini, ingakumbi, ikhadi yayo elingqingqwa, iquka indlela cecum, ekunyukeni, ezinqamlezayo zisihla colon kunye sigmoid, ebangela isikali. It yahluke kuyaphi isakhiwo ikhadi obhityileyo. Kananjalo isebe ashinyeneyo ezisebenza umsebenzi eyahlukileyo ngokupheleleyo.

microflora Eqhelekileyo kuqwalaselwa ngamandla elungeleleneyo, eziphilayo ezintsonkothileyo. S ukwakheka uphawu oluthile, nto leyo iquka iintlobo abangaphezu kwamakhulu amahlanu iintsholongwane. Abameli eziphambili bifidobacteria ziquka anaerobic kunye lactobacilli aerobic.

microflora isisu yenza ngolawulo cholesterol ukutya kunye inyongo acid ithintela ukukhula ezincinane yayintsholongwane eyosulela, ukuqinisekisa, uzinzo (ukumelana amazwe) lomzimba. Ngaphezu koko, lo ecosystem ngaphakathi inxaxheba kwiinkqubo enzymatic iiprotini, ukugaywa otyebileyo kunye nokwenziwa kwe fibre, carbohydrate eliphezulu-ezinto eziphilayo kunye nucleic.

microflora isisu i nxaxheba electrolyte ukutya esebenzayo, kuyondelelaniswe umsebenzi antibacterial, iivithamini K, C, ascorbic acid. Ngoko ke, lo iyonke lonyuka ukuxhathisa kwiimpembelelo egwenxa evela ngaphandle. Imisebenzi microflora kwakhona iquka ezigulela of substrates zemveli kunye zithe zadala. Noko ke, ezinye iintsholongwane bayakwazi ukutshintsha ubume eekhemikhali zizinto ezinetyhefu, benikela kubo engenabungozi. ecosystem isisu ababandakanyekayo nokukhuthaza motility (umsebenzi weentshukumo) lomzimba kunye nenkqubo kuqheleke ekususeni imixholo emzimbeni.

microflora Mhlali yohlulwe (a rhoqo), a otshintsho (okwexeshana) non-yayintsholongwane eyosulela (eluncedo), phantsi kwemiqathango ethile yayintsholongwane eyosulela (luncedo hi mpimo lowutsongo kwaye endaweni ekunene), yayintsholongwane eyosulela (yingozi abangele). Yenziwe ngoobani kunye imali bacterium esoloko itshintsha, kodwa umlinganiselo kobungakanani nomgangatho uzimisele. Ngoko, intsalela okuhambisa igcinwa. Ekubeni kungalingani elibukhali kwenzeka dysbiosis.

Njengoko kukhankanyiwe ngasentla, emathunjini benze imisebenzi ngemisebenzi. icandelo Thin elijongene ukuphunyezwa iindlela ezisisiseko ukwetyisa kokutya kunye nokufunxwa izondlo kungena nkovu kunye negazi. Kulo mzekelo, i motility wamathumbu inikwa umsebenzi umzimba ring ngaphakathi kunye nokuqaqamba yangaphandle longitudinal. Xa le ikhutshwa phandle nge ukukhwezela juice chyme secreted yi injeke kunye umzimba ngokwawo, kunye nokuphakanyiswa chyme. isakhiwo dystrophy yethumbu likuvumela ukuba wenze icandelo obhityileyo segmentation ngesingqi, pendulum, indihlaziya kunye kwamathumbu peristaltic.

isebe umzimba ashinyeneyo yenza umsebenzi kule ndawo. Kukho kwenzeka Ukuzuza umxholo kunye nokususwa ngamaxesha yomzimba zigqithiswe ukutya. Isisu isakhiwo kwezihlunu kule sayithi likuvumela ukuba wenze iimpompo peristaltic, pendulum, anastaltic, ukuncitshiswa basafunda kunye segmentation ezinesingqi.
