Haku mele 'ana kanaka tuha

Tuha mea he aniani moakaka wai ka ole waihoʻoluʻu. 'O kēia ka malu o ka salivary glands ua hoʻokaʻawaleʻia i loko o ka moʻolelo lua. Ua 'oi aku ka ono pokole, e kiko'ī a, lubricates mama ai. Eia hou kekahi, tuha he antibacterial waiwai, lākou ma ka hoʻomaʻemaʻe i ka moʻolelo lua, ua ālai 'na niho mai ka pōʻino. Aie i ka alo i loko o ka haku mele 'ana o secretions i loko o kou waha nā'ūhū hoʻomaka i ka digestion o carbohydrates. He 'atikala e kamailio e pili ana i ka' ole a me ka hana ana o kanaka tuha.

Ano o ka salivary glands

Mau glands ke aupuni 'ma ka anterior hapa o ka digestive'āpana, i ke kūlana i loko o ka hoʻolako' maikai moku'āina o kanaka ku una ha lua a me ka pololei komo i loko o ka digestion kaʻina. Ke salivary glands ma ka lapaau hiki ke maheleia i loko o ka poe liilii, a me ka nui. Ka mua nā buccal, molar, labial, lingual, palatal, akā, mākou e oi hoihoi i ka nui salivary glands, no ka mea, tuha ua ka hapanui hoʻohana i loko o ia mau mea.

Mau kino nā ka secretion sublingual, submandibular, parotid gland. Mua, e like me ka inoa hoʻohuʻu, ka mea, ua aia i loko o ka sublingual pa ma lalo o ku una i ka mucosa. Submandibular ma ka lalo o ka iwi ā. Ua nui nō ka parotid glands, oia no kekahi mau lobes.

It E e kaulana i ka poe liilii, a me ka nui salivary glands mai i pee tuha pono, ka mea, paka kūikawā huna, a me ka tuha hanaia wā kēia mea iʻike i ka moʻolelo o ka lua ua kawili pu ia me nā kumu mua.

biochemical haku mele 'ana

Tuha i ka pH kiʻekiʻe o 5,6 e 7,6 a maupaʻa 98,5 pakeneka o ka wai, a me kekahi mau kumumea oihana mua, paʻakai o na nāʻakika, mekala 'åkilikai metala cations, kekahi nā wikamina, lysozyme a me nā nā'ūhū. Ke aloha kumu waiwai i loko o ka haku mele 'ana - nā polokina i i synthesized ma ka salivary glands. Part o ke kumuʻiʻo mea lāʻau lapaʻau kumu.

nā'ūhū

O nā mea a pau o ka waiwai i e i ke kanaka tuha, i ka mea nui hoihoi i nā'ūhū. Kēia ke aloha 'ona me ka proteinaceous ka molekumu o, a i hanaʻia i loko o ke kino keena, a hōʻeleu i Nine Inch keʻano o ka hanaʻana ' ia ma loko o laila. It E e hoʻomaopopo i ka'ūhū ua ole hanaia kekahi Nine Inch loli, ka mea malama i ke ano o ka hōʻeleu, akā, i ka mea ia manawa ke noho ma kā lākou haku mele 'ana a me ka' ole i ke aʻo.

He aha nā'ūhū i komo i loko o ka haku mele 'ana o ka tuha? Ke kumu nui o ia - ia maltase, amylase, ptyalin, peroxidase, oxidase a me nā kumuʻiʻo waiwai. Ka mea, i nui oihana: paipai i ka liquefaction o ka ai, paka o ka puka mua Nine Inch aaioee, hana i ka hana a me ka bolus mucous waiwai - mucin - Hoamakeikekula ia ia. E kau ia wale, nā'ūhū mea i kekahi hapa o ka tuha, moni 'ia o kaʻai, a kōkua kona hooholo i loko o ka'ōpū ma ka esophagus. Oe Pono e hoomanao i kekahi mea: ai me ka maʻamau a mama i loko o ka waha mea wale no he iwakalua a kanakolu kekona, a laila, komo i ka opu, salivary nā'ūhū akā, hiki ma hope o kēia hana mau ia i ka hopena ma luna o ka bolus.

E like me ke iao? Haʻawina, he huina o nā'ūhū hana ma luna o ka ai no ma kahi o kanakolu minuke, a hiki i ka manawa, i ka wa e hoʻomaka e lilo gastric wai.

Other 'ona i loko o ka haku mele' ana o ka

Ke uie kekahi hapanui hewahewa ana o kanaka ma ka tuha i pūʻulu-ho'ākāka antigens e hoʻopili like i na antigens o ke koko. No hoi, ka mea i malama i ho'ākāka 'nā polokina - phosphoprotein komo i loko o ke kahua o ke kahua niho plaque a me ka tartar, a me ka salivoprotein ka hoʻopukaʻana i ka palapala moʻopane ma na niho fosforokaltsievyh pili' o Randy.

Small dala o ka tuha nā naʻokoko a me kona nā mea kemika, glycerophospholipids, noa momoma nāʻakika, hormones (estrogen, progesterone, cortisol, testosterone), a me kela nā wikamina a me nā waiwai. Nā minelala hao i na anions koloriside, bicarbonates, iodides, phosphates, bromides, fluorides, paʻakai cations, makanekiuma, hao, potasiuma, kalipuna, strontium, ke keleawe a me na mea e ae. Tuha, wetting a e hoopalupalu ana i ka ai, e hōʻoiaʻiʻo i ke kahua o ka bolus a me ka mea hiki i ke kaʻina hana o ka moni 'ia. Food ma hope o impregnation ua hoolilo i ka malu loiloi mua Nine Inch lapaau mua i loko o ka waha, ma a ka α-amylase carbohydrates, hapa 'ia' hydrolyzed i maltose a me dextrins.

oihana

Mākou i hana ia me ka mana o ka tuha, akā manawa e ka kamailio ana ia mau mea i loko o aku au mamuli. No laila, gland ulu i ka malu, ka mea, ua hui pu ia me nā waiwai a me ka hana tuha. He aha ka hana e hiki mai ana? Tuha hoʻomaka e hoomakaukau ai no ka hope digestion i loko o ka duodenum a me ka'ōpū. Penei, kēlā'ūhū e pili ana i ka haku mele 'ana o ka tuha, e hōʻeleu i kēia kaʻina kekahi mau manawa, splitting i loko o liʻiliʻi eiiiiiaiou (monosaccharides, maltose), kekahi eiiiiiaiou o nā huahana (polysaccharides, nā polokina, carbohydrates).

I loko o ka noiʻi ka mea i loaʻa ia, koe wale no ka liquefaction o kaʻai i loko o kanaka tuha he nui i hana 'ē aʻe. Penei, ia lākou ma ka hoʻomaʻemaʻe i ka moʻolelo mucosa a me na niho o pathogenic microorganisms a me kā lākou mau metabolic huahana. Aiiay kūlana i immunoglobulins a me lysozyme i komo i loko o ka haku mele 'ana o ka biochemical tuha. E like me ka hopena, i ka secretory hana o ka moʻolelo o ka mucosa mea humidified, a me ia mea i pono ana no ka mau-ala amo ana o Nine Inch ma waena o ka tuha a me ka moʻolelo mucosa.

fluctuations i loko o ka haku mele 'ana o ka

Ka waiwai a me ka Nine Inch haku mele 'ana o ka tuha loli e like me ka māmā a me ka ano o ka secretion o ka pathogen. No ka laʻana, ka wā hoʻohana chocolates, biscuits, hulina i mahuahua lactate a me ka monakō koko pae ma ka hui tuha. Iloko o ka stimulation o tuha secretion ma ka paʻakai lehulehu me ka nui loa maoli, bicarbonates, i kekahi mau mea hoemiia iodine a me ka potasiuma. Haku mele 'ana kanaka tuha i nicotine nā thiocyanates mau manawa nui like me nonsmokers.

Ka maʻiʻo o kekahi mau waiwai loli aʻe ma lalo o kekahi pathological kūpono a me nā maʻi. Ke Nine Inch haku mele 'ana o ka tuha undergoes kela la i keia fluctuations, a me ka hilinaʻi nui ma luna o ka makahiki, e laʻa me, i loko o ka kūpuna ua nui hoonuiia pae o ka kalipuna. Nā loli i e pili ana i intoxication a me ka lāʻau hooponopono. No laila, he mea he hoopaapaa emi ma ka salivation i dehydration; ma mimikō maoli o ka huina o ka monakō koko; ma ka hihia o ka uremia maoli ka maʻiʻo o koena naikokene. I ka mea, ua hoʻololi i ka haku mele 'ana o kou tuha, ka pilikia o ke kahua niho maʻi a me ka digestive kāna hana.

secretion

Maʻamau, no ka lā no ka makua ua anao? Aou i nā nā lika o tuha, ka secretion i kela mea haoʻa i: i ka hiamoe i ka palena haʻahaʻa (min - emi o 0,05 mililika me) ma lalo o wakefulness - ma kahi o 0.5 ka pono no minuke, ka wā hauma¯na salivation - no minuke i kahi o 2.3 ka pono. Huna anao? Aou i kēlā me kēia gland, ua hui pu ia ma ka waha i loko o ka hoʻokahi waiwai. Una loli (tuha 'ole i hui) ua wehewehe aku ma ke alo o ka paʻa microflora, oia hoi o ka koʻohune, spirochetes, fungi a me kā lākou mau metabolic huahana, e like me salivary aeee (leukocytes mea i E neʻe i loko o moʻolelo o ka luaʻano nui ma ka nui aʻe ana), a kuu iho epithelial keena. I ka haku mele 'ana o ka tuha, ma ka hou, ua kaawale mai ka nasal lua, mucus, erythrocytes.

hiʻona salivation

Salivation ua noho mana ana ma ka autonomic ko mākou hopohopo nenoaiu. nō kona oaio? ia i loko o ka medulla oblongata. Ma ka stimulation o parasympathetic a hāʻule pahū wale paka nui mea o ka tuha me ka haʻahaʻa kumuʻiʻo maʻiʻo. Conversely, kōkua aloha o stimulation komo ai secretion o ka uuku nui o ka h ÷ wai.

Salivation emi no ka mea, o ka makau, stress, dehydration, ia aneane aɃe ka wā i ke kanaka hiamoe. Amplification kaawale ia lŘlŘ ma lalo o ka hana o kaʻaiʻana a me ka olfactory stimuli, a me ka hopena o ÿole mechanical stimulation hua e nui (particles), oiai e kamaiʻilio ana o ka ai.
