Hanganga me te mahi o nga repe salivary

I roto i te anotau Middle reira ko te ara ngā ki te kitea i roto i te hara e kore e ranei. I whakaekea ia ki te ngana ki te raihi maroke. Ki te kore i taea e te tangata horomia reira, ka kitea he ahau. Na he uaua ki te whakapono i te reira, engari i te ngakau o te tikanga taua ko te mahi o te repe salivary. Ka tenei kaupapa, me te kia whakatapua ki to tatou tuhinga.

Āhuatanga o te hanganga o te pūnaha kūnatu tangata

pūnaha kūnatu aroaro o te tangata i roto i rua nga wahi. Tenei "ngongo" haere-i roto i, i huaina nei ko te wahi kūnatu me te repeure. Tata te huna hoki matū motuhake - whākōkī. tere ratou ake tauhohe matū, e tauturu wahia iho te kai i roto i te wahi. I roto i te tangata, e toru ngā momo o repe. ngā te mua te salivary. E tū ana i roto i te kōhao-waha.

He aha te mea te mahi o te repe salivary? whakarato rātou i tukatuka tuatahi o te kai. Ahakoa whākōkī e kei huware, nehenehe o piri warowaihā matatini anake ki ohie.

Nakunaku i roto i te kōhao-waha

haamata whakamana te mahi o te repe salivary i muri anake puta tātari-waha i runga i te reka o te kai, me te pāmahana. tupu ana tēnei ki te awhina o ngā tairongo kei roto i te mucosa, - receptors.

Kia i te mangai, nana te kai kei te me kua machined te whakamahi i te niho. I roto i te tangata, He rerekē ratou. Tei runga i te hanganga, puka me te mahi wehewehe nga incisors, canines, molars iti, me te nui. Ka puta mai hoki, me te tukatuka matū o kai ki huware.

Hanganga me te mahi o nga repe salivary

I roto i te tangata, i reira e toru o nui takirua repe salivary: hūare, submandibular me sublingual. Kei te tuatahi i roto i te rohe o uaua masticatory. Ko atu i te karere kanohi, kakī iatuku me te rua ratou. Ko te wāhi sublingual tuwhera aerodynamics o repe submandibular. E tukua ana ratou ki manga o te iatuku kanohi. Ko Sublingual te iti i roto i te rahi i roto i te whakarārangitia. E tū ana i roto i te hipi Pāoa. Hoki repe salivary iti ko te palatine, reo, labial, buccal me te titiwha. A tuu i to ratou localization he mucosa-waha.

whakaritea mahi repe salivary i roto i te nakunaku te matua i te hanganga o te kikokiko, i hanga e ratou - ara, te epithelium glandular. Kei tēnei kikokiko o iti, pūtau piri Kikī. Nā ki tenei hanganga hangaia e te arai tūturu i waenganui i te rauropi me te taiao.

Ko te hanganga o te huware

Mai salivary mahi repe rite mākū me te hanganga kai te wāwāhi tuatahi i roto i o ratou secretions he wai, me te ngā whākōkī. Ko te āhuatanga ōkiko o te huware ko te wai muco-piripiri. Ko wai ko tona turanga, noho neke atu i 98% o te hanganga katoa. Whākōkī, e ngā amylase, maltase me lysozyme digested warowaihā. ōritetanga mucous o huware piri taonga ngā - mucin. taonga ahurei he ira parotin. Kei te kitea i hoki te reira i roto i te huware, a ka taea e whakakaha te tohu.

Kei te tohaina tonu te kōhao-waha kohuke me te mea organic. Kei te rōpū tuatahi katote konutai, pāhare pāporo, konupūmā, silicon, konupora, parahi, me te ratou te pūhau, pākawa waro me te phosphates. kaipōti Organic o huware he pūmua, whākōkī, hormones me huaora.

Ko te ōrau o ngā huānga raraunga kore he tamau. kia rerekē ngā huānga Composition huware i runga i tau, te huru hauora, hanganga kai, te aroaro o peu kino i roto i te tangata rānei. Ko te kupu, Ko nui teitei te taumata o te thiocyanate i kaipaipa, mai tenei taonga e haamou i te tāoke o paowa tupeka. Ki te tau, huware tangata he nui ake ihirangi o te konupora me te konupūmā.

lysozyme

Ko te ingoa tuarua o tenei taonga - muramidase. no reira ki te rōpū o whākōkī hydrolytic. I tua atu huware, he lysozyme i te wai roimata, te anga o te wahi gastrointestinal, hūpē nasal, toto, ate, wheua ngohe. He rota o reira, me te i roto i te waiu uma. He meka ngā ko e i roto i te tangata nui tenei mea nui atu i roto i kau. A i runga i te wā, kei te piki haere te nui o te lysozyme i te waiu.

Muramidase ahei o te awhi nga taiepa pūtau o huakita. E whakamārama ana tēnei ona āhuatanga ringihia. Rich i roto i te lysozyme me ma hua manu. I roto i te rauropi tipu kei roto tenei taonga horseradish, te keha, te kāpeti me te rarihi.

Amylase me maltase

Ko te mahi o whākōkī o repe salivary - ko te matua te tohanga o nga mea ngaro ki te wahia iho polysaccharides. Mea rawa i reira e pā ana ki e rima tekau. Ko te hunga ārahi he amylase me maltase.

e karangatia hoki warowaihā Matatini huka. Otiia e kore e tenei tikanga e he reka ki te reka ratou. Na, he taonga i roto i polysaccharides o takenga huawhenua te kai katoa. Ko reira te mea he reka reka i roto i to ratou wāhinga. Tenei āhuatanga Ko e tika ana ki te meka i roto i te akoranga o tenei tukanga hua monosaccharides, huka ohie ranei. E ratou he reka.

He aha te digested whakato kai te hohoro ai te? Ko te take i timata te whākōkī huware ki te wahi i raro warowaihā i roto i te mangai kua. Ko pūmua me warowaihā wahia iho ki waetahi anake i roto i te kopu. whiwhi hoki warowaihā reira he kua wahia me te rite mō te absorption. Na reira, kai te tipu nui whakahaere te mahi o te pūnaha kūnatu.

Āhuatanga whākōkī huware i reira whakamahia whānuitia i roto i te ahumahi. Hei tauira, amylase, e roto i rewena, tāpiri ki tunua taonga ki te whakapai ake i to ratou kounga. Ko ratou aroaro i roto i teretere e te kaha ki te tere digested māngaro.

mucin

Ko hoki te mahi o te repe salivary he makuku mangai me matūriki kai. mahi te reira i mucin. huaina ana tēnei taonga ko hūpē. Otiia i roto i te meka ko reira he pūmua matatini hanga ake o, i roto i te tua ki te amino waikawa, e ngā warowaihā. hanga Mucin huware Kaore mai i te mea i te kaha ki te pupuri i te wai. haati kokokiko ia tamâraa kai, hanga nehenehe ratou o irava atu i roto i te wahi kūnatu. I tua atu, hūpē hoki kua ringihia āhuatanga. ārai te reira i tāpiritanga kitakita ki te mucosa-waha, me te ratou whakaeminga i roto i tona kōhao.

Kia pehea te he huware

puta Tukanga huware kahuki. Ahakoa irritates kai i te kai receptors arero, me te mangai. hua tenei ponana io e mahi i runga i muka tairongo i roto i te oblongata medulla. He ko te pokapū o te salivation. Mai i hoki ki te repe ana ponana. Ka rite ki te hua, salivate. I roto i te ra e whakaputaina ai i roto i te tangata ki te 1.5 rita. Salivation i roto i te kai e tae mai tika ana ki te mangai, ka karanga te unconditioned.

Otiia ka taea e puta i te reira i waho te aroaro o te kai. Hei tauira, e taea te taratahi huware i roto i te tangata i te aroaro o te kai tona whakapakoko ranei, tikanga o te kakara, ranei ara whakaaro e pā ana ki reira. mahara Just, rite te rēmana kawa titiro reira. meinga tonu tenei salivation. Otiia kua reira ki te waiho i te pūpū makatuunga.

Kei te mea te reira e kore e whakaritea e tu i roto i te wā huware moe. Whakaiti tona rahinga, me te i roto i ngā āhuatanga ahotea taimaha, nga mahi o te rehunga, ki te maroketanga, disorders karere, menopause, hēnga o ōna whatukuhu, me te mate huka.

Kei te mohiotia te reira i rite te mate ma'i i roto i nei e kore e ranea te nui o huware. Kei te karangatia e te reira i xerostomia. Tohu o te mate, ko te mangai maroke, pokey nui o te huware, reka kai oreraa, te mamae i roto i horomia a korero.

horomia kai

Kei te iti hoki taiepa esophageal i te wa ano, me te te neke i te puranga ki te wahi tino whakawhānuitia o te tinana pūnaha - puku.

Ko te kupu, nga mahi o te repe salivary tangata e whai ake nei:

- whākōkī - nakunaku o te warowaihā matatini ki ohie;

- paruru- - neutralization o microorganisms, te whakaora o te mucosa-waha, ki te whakarato i te kiriata i runga i te tohu niho, te tiaki ratou i waikawa organic;

- kūnatunga - mākū, me te tamarûraa o kai;

- Hormone - te whakarato mineralization o te kopa niho totoka;

- horoi - elution me te tango i te kōhao-waha o matūriki ke, ngā toenga kai, microorganisms me tāoke.
