Kugaya ari nemumuromo mhango

Kugaya - ichi panzvimbo yakaoma mutoo, iyo ipfupi kuti kukamurwa guru mamorekuru kwemapurotini, kwemafuta uye Mahydrocarbon pamusoro monomers, ayo nyore kunyura kubudikidza mumasero nhengo. Munzvimbo dzakasiyana-siyana dziri zvomudumbu turakiti kuputsa siyana yeimwe, ayo zvino yokuita zvinoitwa mucous Kamudzira pamusoro ura duku uye dzakapararira muviri. Kugaya kunotangira muromo.

Tisati takurukura kuti kugaya iri mumuromo, anofanira kanenge muchidimbu kuzivana ayo mamiriro.

The nemamiriro nomumukanwa mhango

The anatomi inogona kupatsanurwa nomumukanwa mhango mapoka maviri:

• Buccal mhango (nzvimbo pakati nemiromo uye mazino);
• Chaizvoizvo dzaiita zvokutaurwa mhango (mazino achingopiwa, pfupa uye mhepo diaphragm muromo);

Nechimwe chine maatomu akafanana zviri nomumukanwa mhango iine pachake nerevane ndiye imwe chikafu kugadzira.

Meno anokonzera zvokuimba kunorapwa zvokudya zvikukutu. Achibatsirwa canines uye incisors murume inoruma zvokudya, ipapo duku molars runoputsa yake. Basa molars airarama vachidzipukuta zvigadzirwa.

Mutauro - huru tsandanyama nhengo kuti kwakunoitwa kusvika pasi nomumukanwa mhango. Language haasi chete mumabasa kubudiswa zvokudya, asi ari kutaura kwacho. Kufambira ichi tsandanyama nhengo mixes weupfu chikafu ne mate uye anoumba munhu bolus. Uyezve, riri munzvimbo rurimi rinenge gustatory, chafariz, uye zvokuimba marwadzo receptors.

mumasero mate - parotid, submandibular uye sublingual mumasero iri mumuromo vachishandisa mutsinga dzinofamba nemukaka. basa ravo chikuru - kugadzirwa uye excretion mate, izvo kunokosha kuti kugaya. Mate Mabasa sezvinotevera:

• Zvomudumbu (mate rine makemikari achibatsirwa iyo cleavage carbons);
• Protective (mate rine lysozyme, iro rine simba bactericidal ehupfumi Uyezve, muna nemate vari immunoglobulins uye coagulation zvinhu mate anodzivirira dzaiita zvokutaurwa mhango kubva nokuomesa ..);
• Excretory (pamwe mate akasunungura zvinhu zvakadai urea, munyu, doro, vamwe zvinodhaka);

Kugaya ari nemumuromo mhango: zvokuimba kutotanga

The zvokuudzwa mhango anogona kupinda kupfuura siyana zvokudya uye zvichienderana ayo kusachinja-chinja zvinonzi kana pakarepo Kutamiswa kupinda yegurokuro panguva pakuparadza chiito (kunwa, mura chikafu) kana kunosvika machine, izvo hwezvekukurukurirana mamwe maitiro kugaya.

Sezvambotaurwa, kushandisa mazino chikafu gaya. Rurimi sangano aifanira ide rikamunya muchindwi zvokudya pamwe mate. Achifuridzirwa mate dzinopomhodza chikafu uye wakafukidza pamwe madzihwa. Mucin, iyo iri nemate, anotora chikamu paumbwe chikafu bolus, vakazochinja unopinda yegurokuro.

Kugaya ari nemumuromo mhango: zviri enzymatic kutotanga

The Zvinoumba mate uye vamwe makemikari izvo zvinobatanidzwa munyaya manyowa pamusoro Polymers Panewo. The zvokuudzwa cleavage pamusoro kabhoni iyo yave kuitika ura duku.

Mate ine enzayemu yakaoma inonzi ptyalin. Achifuridzirwa kuora kwavo kunoitika disaccharides kune polysaccharides (runonyanya ndiro maltose). Naizvozvo maltose kufurirwa nomumwe enzayemu wakanamatira kuna monosaccharide shuga.

The refu zvokudya riri mumuromo, uye kubatwa enzymatic zvinokonzerwa, nyore kunoitika kugaya mune dzimwe dzose yemakwenzi turakiti. Ndokusaka vanachiremba nguva dzose akakurudzira bedzi unogona kutsenga.

Panguva kugaya ichi pamuromo inoguma. Bolus anoudzawo uye kusvika pamudzi rurimi rinotanga pakuparadza dzepanguva kwacho umo zvokudya zvinoenda yegurokuro uye zvadaro mudumbu.

Kuti muchidimbu, munzvimbo nemumuromo mhango kuitika pezvakaitwa zvakadai vachikuya kwezvokudya Kuongororwa waro palatability, mate wetting, nokusanganisa, uye zvikuru kuora makabhohaidhiretsi.
