Ekugayeni em- ngomlomo

Ekugayeni - le nkqubo kunokuba nzima, nto leyo azezi ukuqhekeka molekyuli amakhulu iiprothini, amafutha kunye hydrocarbon phezu monomers, apho wendele lula ngokuthi iiseli ze eziphilayo. Kwiindawo ezahlukeneyo wokugaya ndoyidiliza le khompawundi ezahlukeneyo, ezithi ke ngoko lilo inwebu kwiinwebu emathunjini amancinci kwaye wonke umzimba. Ekugayeni iqala emlonyeni.

Ngaphambi kokuba siqwalasele indlela ukwetyisa kwi emlonyeni, kufuneka ubuncinane ngokufutshane sazane kunye nesakhiwo sayo.

Ubume kwisisu ngomlomo

Le komzimba lungahlulwa-hlulwa kwisisu yomlomo ibe ngamaqela amabini:

• kwisisu Buccal (isithuba phakathi imilebe namazinyo);
• Eneneni komgodi somlomo (amazinyo kungaphelelanga, ithambo kunye uvalo umlomo moya);

isiqalelo ngalinye kwisisu ngomlomo umsebenzi walo yaye linoxanduva processing ukutya ethile.

Amazinyo banoxanduva unyango ngomatshini ukutya okuqinileyo. Ngoncedo canines kunye siphume umntu izinja ukutya, ngoko ezincinane imihlathi ubulala bakhe. imihlathi Umsebenzi yancitshiswa kwiimveliso ngokukhuhla.

Ulwimi - yinto ilungu dystrophy enkulu edibanisa ukuya ezantsi kwisisu ngomlomo. Ulwimi nje kuphela inxaxheba ukuhluzwa ukutya, kodwa inkqubo intetho. Ukuhambisa eli lungu dystrophy ixutywa ukutya olungumgubo kunye namathe yaye yakha bolus. Ngaphezu koko, ukuba ibekwe ngolwimi esiqwini gustatory, thermal, kunye receptors iintlungu ngoomatshini.

kwamadlala amathe - parotid, amadlala submandibular kunye sublingual elime kule emlonyeni nge duct. Owona msebenzi wabo - imveliso kunye kukhuthaza amathe, nto leyo ibalulekileyo ukuze ukwetyisa. imisebenzi amathe ngolu hlobo lulandelayo:

• Sokugaya (amathe iqulethe enzayim ngoncedo apho carbons cleavage);
• Zothintelo (amathe iqulethe lysozyme, nto leyo eye iipropati esinamandla bactericidal Ngaphezu koko, ngamathe ezi immunoglobulins nezinto coagulation Amathe ukhusela kwisisu ngomlomo omiswe ..);
• Excretory (ngamathe wakhululwa izinto ezifana urea, iityuwa, utywala, ezinye iziyobisi);

Ekugayeni em- ngomlomo: Isigaba mechanical

Komgodi ngomlomo unako ukungena ukutya kakhulu ezahlukahlukeneyo yaye ngokuxhomekeke guquki lwalo mhlawumbi kwangoko igqithiselwe emphinjeni ngexesha yokuginya isenzo (iziselo, ukutya engamanzi) okanye ubonakalisa machining, leyo lula neenkqubo zokunceda ekugayeni.

Njengoko sele kukhankanyiwe, esebenzisa bubomi amazinyo ukutya. movement Ulwimi kwakufuneka ukuba usikhwezele ukutya etshisa kunye namathe. Phantsi impembelelo amathe yenza ukutya zigutyungelwe yencindi yomlomo. Mucin, nto leyo uqulathwe ngamathe, uthatha inxaxheba lokusekwa bolus ukutya, nto leyo iya kamva emphinjeni.

Ekugayeni em- zomlomo: kwisigaba enzymatic

Le Ukwakhiwa namathe kunye ezithile enzayim aqukiweyo kule yokubola Iipholima nazo zibandakanywe. Le cleavage ngomlomo carbon ethe bayahamba emathunjini amancinci.

Amathe iqulethe esimbaxa enzyme ebizwa ptyalin. Phantsi yempembelelo ekonakaleni kwabo kwenzeka disaccharides ukuba polysaccharides (ubukhulu nto maltose). Kamva maltose kuchatshazelwa omnye enzyme lwanamathela glucose monosaccharide.

Okukhona ukutya emlonyeni, kwaye buyakwazi yeziphumo enzymatic, lula oko kwenzeka ngenxa yesisu kuzo zonke ezinye iindawo phecana esintu. Kungenxa yoko le nto oogqirha usoloko bacebisa ukuba nje unako ukuhlafuna.

Kule kokudla emlonyeni iphela. Bolus udlula phezu nokufumana ka ku kuso aka ulwimi uqala yokuginya inkqubo reflex apho ukutya kuya kuvuleke iminxunya yaye emva koko kuya esiswini.

Ukushwankathela, em- yomlomo kwenzeka iinkqubo ezifana besila ukutya, uhlalutyo Ubumandi yayo, amathe xa belele, ukuxuba, kwaye carbohydrate ukubola zaseprayimari.
