Sublingual ne mafi karami a size daga cikin jera. Suna located a cikin eponymous folds. Domin kananan salivary gland ne Palatine, lingual, labial, buccal da matauni. Wajen da su sarrafawa ne na baka mucosa.

Salivary gland shine yake aiki a narkewa aka ƙaddara da farko ta tsarin da nama, wanda suka kafa - wato, glandular epithelium. Wannan nama kunshi kananan, tam cushe Kwayoyin. Saboda wannan tsarin halitta wata halitta shãmaki a tsakãnin kwayoyin da kuma muhalli.

A abun da ke ciki na yau

Tun salivary gland shine yake aiki a matsayin wetting da primary tsagawa abinci abun da ke ciki a cikin secretions ne ruwa da kuma daban-daban enzymes. The jiki Properties na yau ne a muco-m ruwa. Wannan ruwa ne harsashinsa, mamaye fiye da 98% na jimlar abun da ke ciki. Enzymes, wanda sun hada da amylase, maltase da lysozyme narkewar carbohydrates. Mucous daidaito na yau dora musamman abu - mucin. Musamman dukiya yana parotin hormone. Haka kuma an samu a cikin yau kuma za a iya karfafa da enamel.

The baka rami ne kullum kasaftawa ma'adinai da kwayoyin halitta. Na farko da kungiyar qunshi sodium ions, potassium, alli, silicon, magnesium, jan, kazalika da su chlorides, carbonates da phosphates. Organic yayan yau ne sunadarai, enzymes, hormones da kuma bitamin.

Amma da yawan data abubuwa ne ba m. Abun da ke ciki yau abubuwa za su iya bambanta dangane da shekaru, kiwon lafiya yanayin, abinci abun da ke ciki, gaban miyagun halaye a cikin mutane. Saboda haka, matakin na thiocyanate a Club ne yafi hakan, tun da wannan abu neutralize da gubobi na taba hayaki. Tare da shekaru, mutum yau ne karin abun ciki na magnesium da alli.

lysozyme

Na biyu sunan wannan abu - muramidase. A nasa ne a rukuni na hydrolytic enzymes. Bugu da ƙari yau, lysozyme ne a cikin hawaye ruwa, da harsashi na gastrointestinal fili, hanci gamsai, da jini, hanta, guringuntsi. A yawa da shi, kuma a cikin nono. An ban sha'awa Gaskiyar ita ce, a cikin mutum wannan al'amari yawa fiye da a saniya. Kuma a kan lokaci, da adadin lysozyme a cikin madara na karuwa ne.

Muramidase iya lazimta a kansu da cell ganuwar da kwayoyin cuta. Wannan ya bayyana ta disinfecting Properties. Rich a lysozyme da kwai fari. Daga cikin shuka kwayoyin wannan abu ya ƙunshi horseradish, kabeji da kabeji da kuma radish.

Amylase da maltase

The aiki na enzymes daga salivary gland - shi ne da farko da kasafi na asirin karya saukar polysaccharides. Gaba daya akwai game da hamsin. A manyan wadanda su ne amylase da maltase.

Complex carbohydrates kuma ake kira sugars. Amma wannan ba ya nufin cewa su ne zaki da dandano. Saboda haka, duk abinci ne mai arziki a cikin polysaccharides na kayan lambu asalin. Amma akwai wani zaki da dandano a cikin tsakiyan nonon mata. Wannan sabon abu ne saboda gaskiyar cewa a cikin shakka daga wannan tsari na samar monosaccharides, ko sauki sugars. Bã su da wani zaƙi.

Me ake shuka abinci ne narkewar haka da sauri? Gaskiyar cewa yau enzymes fara karya saukar da carbohydrates a bakin riga. Amma sunadarai da carbohydrates karya saukar zuwa monomers kawai a ciki. Carbohydrates kuma samun akwai riga raba da shirye domin sha. Saboda haka, inji abinci ƙwarai facilitates aikin na narkewa kamar tsarin.

Kadarorin yau enzymes a halin yanzu amfani da ko'ina a masana'antu. Alal misali, amylase, wanda dauke da yisti, kara zuwa gasa kaya don inganta su quality. Amma kasancewarsu a ƙuna yana da ikon hanzari narkewar sitaci.

mucin

The aiki na salivary gland ne ma a bakinka moistening da abinci barbashi. Shi aikin mucin. Wannan abu ne ake kira gamsai. Amma a gaskiya shi ne wani hadadden gina jiki ya tashi daga, ban da amino acid, carbohydrates ana hada. Mucin sa yau danko sosai tun yana da ikon ya riƙe ruwa. Ya ƙunsa chewed abinci chunks, samar da su su iya kara wucewa ta hanyar narkewa kamar fili. Bugu da kari, gamsai kuma ya disinfecting Properties. Yana hana kwayan da aka makala da na baka mucosa, kazalika da jari a cikin kogo.

Ta yaya ne yau

Tsari yau reflex faruwa. Duk da yake cin abinci da abinci irritates rabe harshe, da bakinka. Wannan samar jijiyar cewa aiki a kan azanci shine zaruruwa a cikin medulla oblongata. Akwai cibiyar da salivation. Daga cikin hasken dake fitowa ta mayar da gland. A sakamakon haka, salivate. A lokacin da rana ta aka samar a cikin wani mutum zuwa 1.5 lita. Salivation a cikin abinci da cewa ya zo kai tsaye a bakin, da ake kira unconditioned.

Amma shi na iya faruwa ba tare da gaban abinci. Alal misali, yau za a iya ware a cikin mutane a gaban abinci ko siffarta, ji na wari, ko tunani game da shi. Kamar tuna, shi kama wani m lemun tsami. Wannan nan da nan sa salivation. Amma shi ya kasance wani sharadi reflex.

An ce, kusan ba ya tsaya a waje a lokacin barci yau. Rage ta yawa, kuma a lokacin nauyi danniya yanayi, da ayyuka na maganin sa barci, da dehydration, jijiya cuta, menopause, koda gazawar da kuma ciwon sukari.

An sani a matsayin kullum cutar a cikin abin da adadin yau ne bai isa ba. Shi ne ake kira xerostomia. Bayyanar cututtuka da cutar ne bushe baki, wuce kima danko na yau, abinci dandano insensitivity, zafi a lokacin hadiya, kuma magana.

hadiya abinci

The aiki na salivary gland, wanda ya auku a cikin bakinsa, sa shi yiwuwa a karfafa gabatarwa abinci. By lokacin da abinci da aka yi lõma, an riga mechanically shredded, rigar da kuma partially narkewar. Bugu da ari, yare Firaministan wani abinci dunƙule zuwa makogwaro. Kamar yadda ya shiga cikin esophagus? Wannan shi ne saboda ragi na harshe, da makogwaro tsokoki. A wannan lokaci, da ƙofar airway rufe supraglottic guringuntsi. esophageal bango a lokaci guda ana kuma rage da dunƙule ne motsi zuwa ga mafi kumbura ɓangare na tsarin jikinsu - ciki.

Saboda haka, ayyuka na mutum salivary gland wadannan:

- enzyme - narkewa hadaddun carbohydrates cikin sauki.

- kariya - neutralization na kwayoyin, da waraka da na baka mucosa, don samar da wani fim a kan hakori enamel, kare su daga Organic acid.

- narkewa kamar - wetting da softening abinci.

- Hormone - samar mineralization na m hakora kyallen takarda.

- tsaftacewa - elution da kuma kau daga baka rami na waje barbashi, abinci sharan gona, kwayoyin da gubobi.
