OLawulo iindlela zokwetyisa komntu

Xa amayeza, kukho amagama amaninzi abstruse, nto leyo lula ukuqonda, kwaye umzimba womntu - ukuze yinkqubo entsonkothileyo ukuba abasemagunyeni injongo ethile abaninzi ingcamango ongacacanga kakhulu. Kodwa akukho mfuneko yokuba ube sisazinzulu rocket, ukuqashisela ukuba yintoni umsebenzi lwenziwa yi amalungu ometyiso yomntu. Oku kuthetha ngokucacileyo igama labo.

Njengokuba kude njengokuba sisazi, route - enkulu kakuhle endleleni; wokugaya, okwabizwa ngokuba emathunjini, yeyona indlela apho ukutya kufuneka ityiwe ngaphakathi umntu. Noko ke, kukho inkcazelo enjalo, Kakade, lulula kakhulu, into lifana inkcazelo anecdotal yentloko mission: "Ndiya kudla kuyo." Kodwa uviwo olubanzi isakhiwo kwenkqubo kunye nemisebenzi ayo kusinceda siqonde ngcono indlela inkqubo yokucola ukutya kunye neentlobo zokuphula ukuba ebangela iingxaki emzimbeni kunye nezifo ezahlukeneyo.

Ngoko ke, yintoni inxalenye amalungu kwenkqubo zokwetyisa komntu?

Lokuqala - i kwisisu ngomlomo apho ukutya lubekwa kude kangaka nje machining sokuqala. Nceda hayi nje amazinyo nolwimi, kodwa kwamadlala amathe, kuba enzayim eziqulathwe ngamathe sele ninamathele izinto ezithile.

Okulandelayo, ukutya kuya kuvuleke iminxunya, kodwa ngokungqalileyo, kodwa pharynx, nto leyo ngendlela reflex kunceda ukuba imginye sele elinqunqiweyo ngokushiyanayo kwaye buthathwa ukutya intlama iphela. Yena umphimbo ke ubude tube ngqo ngeesentimitha eziyi-30. umsebenzi wakhe - ngokukhawuleza azise ukutya kungena esiswini, nto leyo inceda izihlunu kunye ngakwimida iindonga epithelium carcinomas.

Ukuba amalungu wendlela yokwetyisa yabantu ukuzama ukwenza amalungiselelo ukuze nobukhulu, nesisu kusenokwenzeka ukuba eyona nto ibalulekileyo. Kule "bag" livela ukwetyisa phantsi kwempembelelo incindi esiswini. amabakala alo ayintloko zehydrochloric acid, bicarbonates, pepsin okanye ezinye enzymes. ngeengcamba ezintathu zihlunu agudileyo ukutshintsha-bolus ngaphakathi esiswini, ukukhawulezisa processing.

Noko ke, asingabo bonke ukudla esiswini - "ikhuni" engenela emathunjini. Ukuba iphecana yabantu wokudla - endleleni, amathumbu - iqonga inde kuyo. ubude ogcweleyo ukuya kwiimitha ezilishumi, yaye kufanelekile oko esiswini, njengoko ngokwaseburhulumenteni liwa, ezifana ifeni okanye frill. Ingxenye esemqoka - emathunjini amancinci, kodwa ke lo duodenum, apho asuka imibhobho injeke cell enzayim ukuyaphula phantsi amafutha, iiprothini kunye carbohydrate senyongo, leyo iqulathe isibindi bile eyenziwe, nayo inxaxheba kwinkqubo iyonke. Le inwebu kwiinwebu ifomu emathunjini villi ezincinci eziliqela ngcembe ufuduke ode ecaleni bolus emendweni, nto leyo wayesele zahlulwe zibe iimolekyuli kwezondlo. Esebenzisa villi kwenzeka kukufakwa lwabo egazini kunye nkovu.

Inxalenye yokugqibela iphecana zesisu - Amathumbu amakhulu. Yayo umsebenzi - lwahlukane ifayibha ngokusebenzisa iintsholongwane ezikhethekileyo ukufakwa fluid kunye ukuqokelelana iintsalela undigested ezo akhiwa njengesihlalo ngokusebenzisa isikali kunye kwazona ngaphandle. kwisahlulo zokuqala yethumbu enkulu ebizwa ngokuba cecum, a nomhlehlo encinane, mhlawumbi umbutho wabantu kuphela ayinayo kuzo ezinye umsebenzi wayo luncedo - appendix.

Njengoko ubona, amalungu ometyiso yabantu azamkelekanga elula oko kunokubonakala kunzima. Le nkqubo imbaxa sengozini ityhefu ngu nokudla imveliso zakhe ebolile okanye izinto okunene enobuhlungu, oko TYALA: loo maphalo zenzeka Ukuphazamiseka pathways, kunye nezinye iingxaki, ezininzi kuzo thina amalungiselelo iphecana yakho zesisu ngokwabo xa esitya ukutya hlafuna embi okanye embi . Ukuba uninzi nzima ukusebenza umzimba wethu kuthatha ngaphaya, ngoko sifanele ubuncinane musa kuphazamisana naye.
