Wakanwa masero: STRUCTURAL features, zvokusarudza mazita uye nenzvimbo localization

Muviri womunhu - ndiyo mamiriyoni masero siyana zvitarisiko, marudzi uye hukuru. Vanoshamiswawo chiduku kuti funga uye kuongorora navo chete nemaikorosikopu. Kutaura zvazviri, masero - ndiro roga Dzokuvaka lining rinenge nhengo, hurongwa uye rose muviri. Pasinei musiyano siyana kuti masero ose ane vakawanda dhayagiramu yechivako chacho. Zvinosanganisira yokunze Kamudzira, nechepakati neerekitironi cytoplasm semiliquid. About rakasiyana-siyana emasero kunogona kuva hurukuro refu, asi nyaya ino ichakurukurwa chete mhando imwe, akadana masero wakanwa. Tichaedza kunzwisisa zvavari, uko dziri uye sei kuti kushanda.

Title mikana

Masero kwakadaro vanozivikanwa pasi mazita akawanda. mutsara wokuti "enterocyte wakanwa", "wakanwa ekzokrinotsid" uye "wakanwa grandulotsit" rinowanzoshandiswa. Latin wakanwa masero anonzi enterocytus caliciformis. Dzimwe nguva shoko rokuti "muchitokisi mbiya," izvo rinotaurawo masero wakanwa. Vose mashoko aya yakaenzana mumwe uye kushandiswa anoreva zvakafanana.

The zita akaratidza kujairika chimiro masero. Vanotarisira sezvinoita varefu, yakatetepa girazi zvishoma kwakamuka kumusoro.

Masero kwakadai ndezvaJehovha epithelium ari mucous membranes uye vari mubasa kugadzirwa madzihwa. Ndivo mumuviri zvose dzevanhu uye mhuka.

Localization. ura

masero wakanwa chikamu anoverengeka epithelial nhengo. Mumwe nzvimbo localization - ura. intestinal epithelium ane panzvimbo kunzwisisa chivakwa. Chine Mhando inoverengeka enterocytes, kusanganisira chikamu ichocho ndicho chinoita, wakanwa acidophilus, beskaemchatye, kwemakemikari anobudiswa, uye dzimwe havaratidzi kusiyaniswa. Vose vari mumasero chete-celled nedzimwe mabasa. Somuenzaniso, chikamu ichocho ndicho chinoita masero epithelial anobatanidzwa parietal kugaya uye Absorção de Água. Wakanwa anokonzera kugadzirwa madzihwa (ona pazasi nehurukuro zvakawanda). Kwemakemikari anobudiswa masero kubereka mahormone turakiti, acidophilus masero Punnett kubereka zvakawanda zvomudumbu makemikari. Basa undifferentiated masero - patsva of epithelium.

Masero wakanwa of ura anoiswa pamusoro intestinal villi. Dzinovakwa musi iwoyo pakati chikamu ichocho ndicho chinoita masero. Pazuva apical chikamu villi uye tubular pakadzika mucous Kamudzira, akadana mumasero liberkyunovymi kana intestinal crypts, masero wakanwa haana kuwanikwa. Kunyange paine chisingawanzoitika anosiyiwa.

Munguva duku ura izvi mhando masero akakura. 9.5% enterocytes - wakanwa epithelial masero. Uyezve, nhamba yavo kunowedzera akananga distal muura. Vari noruvara anoparadzirwa pamusoro mujinga crypts uye villi, avo maduku zvikuru pamusoro villi pachavo.

Airways

Imwe nzvimbo localization wakanwa exocrine masero - the kufema turakiti. Pano mumasero izvi ndizvo anenge 30% of epithelium. Masero vari vakarongawo singly. Inosanganisira vacuoles akazadzwa mucous secretion. Vacuoles mu wokukudza apical chikamu. Mutsipa chikamu sero unotora ari Golgi yakaoma uye mitochondria zhinji. Airway wakanwa Sero microvilli inopiwa, iyo, pashure madzihwa kuva kuchioneka.

madzihwa ari cyclical zvakasikwa, izvo zvinobva zvimwewo zvinoitika, kureva tembiricha uye mwando pamusoro.

Conjunctival wakanwa masero

Akatevera nzvimbo localization masero wakanwa - the conjunctiva maziso. The conjunctival mucosa zvakawanda. Chakavanzika, secreted nemasero izvi akasiyana madzihwa secreted mune epithelium vamwe nhengo. Conjunctival wakanwa masero iri panguva basal rukoko uye vari denderedzwa uye tenderera. Madzihwa, zvavakanga synthesize uye secrete, vakasungwa rudzi samambure kuti rinoburitsa uye anonyora miviri vavatorwa uye utachiona. Panguva kwepfumo, nemambure wakaputsika uye zvakachinja kune medial kumucheto, achibvisa meso kubva marara uye utachiona.

Wakanwa masero rwatata

masero wakanwa varipo vari nzira yokubudisa ducts pakati rwatata. Havana iri yose kureba mutsinga dzinofamba nemukaka, uye avo widest chikamu. Pane exocrine shwanu kuumbwa mucosa.

Parotid shwanu

The mate shwanu zvakare akapfuma mumasero wakanwa. Vari pedyo nemuromo uye secrete madzihwa, kuti rokununura makemikari chipingamupinyi tupukanana. With zera, nhamba wakanwa masero ari mate mumasero ipfupi. Inorwisa utachiona chipingamupinyi simba.

Verenga zvakawanda pamusoro zvinhu

masero wakanwa pave madzihwa insoluble unonzi mucin. Mucin lining mucosa, dzimwe nguva kuunganidza kuti Ukobvu 1.5 mm. Kuti ndinoumba izvozvo, mutsitogennye granules tibatsirwe mvura uye kuzvimba. Madzihwa masero wakanwa ane wandei mabasa. Mudumbu, rwatata uye ura mucosa moisturizes nayo miviri kunosimudzira gastric uye intestinal mukati, chikamu rusvingo kugaya. The conjunctiva kunze humidification ane unodzivirira basa iri mate mumasero - nokuidzivirira.

Antibodies wakanwa masero

Kazhinji antibodies kuti wakanwa masero hatisi muropa. Kana tikaongorora ropa kubva tsinga vanozivikanwa antibodies izvi, zvinoreva kuti murwere ane maronda colitis. Naizvozvo, nokuti antibodies wakanwa sero kuongorora ushandiswe nokuda differential zvokuongorora echirwere zvirwere anogumbura bowel.
