Epithelial zvinyama: pa murindi Muganhu

Kana vanhu kutaura rejira mhando ichi, ndinoyeuka ganda kunyanya, kunyange zvazvo epithelial zvinyama - iwo musimboti, rudzi "murindi muganhu". Iye vaparadzana mumwe nhengo, zviri huri Kuronga mucous. Heterogeneous epithelial zvinyama, marongerwo uye kushanda izvo interconnected neimwe nzira neimwe mhando rejira.

A maitiro zvakafanana kuchiitwa mhando dzose - masero kuti vari pedyo vachionana mumwe, kazhinji akaturikidzana, nokuda chipingamupinyi mashandiro epithelial tishu. Uyewo, zvose zvamarudzi ose epithelial zvinyama zvakafanana ndechokuti ari pedyo zvivako, ivo nguva dzose dzakaparadzaniswa connective zvinyama - inotungamirwa ichi inonzi zimba membrane.

Vakawanda epithelium iri nyore (a chete rukoko) uye laminate (akawanda). Nokudaro, maumbirwo epithelial zvinyama angava akasiyana chaizvo.

Simple epithelium inogona flattened zvishoma muna chimiro. Izvi mhando inonzi squamous. Iye mitsetse mumapapu, tsinga, mwoyo in. Uyewo, masero aya vari okumusoro akaturikidzana ganda uye kunanzvana mucosa.

Hazvina kuoma kuti zvokufungidzira chimiro epithelial masero cubic. Masero aya anowanikwa omumuviri, ducts, mumasero uye renal tubules. Mukuwedzera, ivo vanoumba germinal epithelium ari ovaries kwevanhukadzi uye manhu dzevanhu.

Prismatic epithelium iri nyore uye layered. Masero vane chimiro elongated mazariro. Nuclei mumasero ava "zvakavanzika" bhesimendi Kamudzira pedyo uye kure pemvura. Eya, mudumbu, ane chiso ivo zvinozadzisa, zviri vakarongeka chaizvo - zvakare zvechisimba ipapo neChitatu. Vamwe masero aya chikamu kutsinga dzinouya nadzo - kunhuwidza, kunaka uye kunzwa.

Ciliated columnar epithelium ane zvikuru zvakaumbwa growths kuti kutsanya undulating anogona kusimudzira chinhu kuti ari pedyo navo. Ivo "kurarama" mumhino uye ... ari fallopian zvibereko vakadzi dzinovabvumira kusunda zai kusvika dumbu.

Glandular epithelium inonzi prismatic dzine masero secreting. Dzimwe nguva secreting masero kupfuura columnar. vari kupi masero kuti anogona kusika chakavanzika? Ndicho masero ose epithelial rinenge zvekare nzira specialization. Uye "nyanzvi" vanogona kuva akasiyana chaizvo. Mubasa kugadzirwa makemikari, mahormone, mukaka, madzihwa, ziya, wakisi uye mate. Chokwadi, zvose izvi zvinhu vasingakwanisi kubereka chimwe-celled omumuviri, mumasero yacho, rine masero akawanda epithelial. A sero rimwe chete rinonzi masero wakanwa. Pakutanga vakadaidzwa enterocytes, nekuti vazhinji masero aya ari ura duku. Asi ipapo Zvakazoitika kuti varipo vari conjunctiva weziso uye ari kufema ino, uye ducts ari mumasero.

Apo kwemasayendisiti guru kukweshera uye ngozi kukuvara, muviri runovaka kunzwisisa epithelium - chete munhu kuti nguva dzose une anoverengeka akaturikidzana. Tiri kutaura ganda uye kunanzvana mucosa. On masero ganda pamusoro dzinongoda umo multi-puroteni mapuroteni mumuromo puroteni masero ari muduku, saka musabata ganda uye mucous Kamudzira muromo zviri zvakasiyana.

Epithelial zvinyama basa yakasiyana chaizvo. Pasi apa haasi azere.

The unodzivirira basa. Epithelium chinonditadzisa zvokuimba kukuvadzwa, zvemakemikari kutsva, wabvunza chipingamupinyi pazvirwere uye anodzivirira masero kubva inotsigira mvura kurasikirwa.

Basa nezvekufadza: specialized masero epithelial zvinyama fomu nhengo nezvekufadza.

Secretory basa: chinorondedzerwa zvizere chikamu glandular epithelium.

Absorptive: mune iri ura diki kuburikidza epithelium pamusoro Absorção de Água muviri rinoitwa.

Excretion: ziya mumasero secrete pasingadiwi zvinhu zviri itsvo epithelium kugonawo pokuita filtration, uyewo reabsorption.

Diffusion: kuburikidza nhete epithelium iri ari kufema turakiti kupinda mumuviri uye kubva kutekeshera magasi.

Kuchenesa basa: yemweya epithelium inochenesa mhepo kubva muguruva.

Akaderedza kukweshera: vascular epithelium zvinoderedza kukweshera pakati mudziyo parusvingo uye neropa masero.

Sezvaunogona kuona, yakawanda mashandiro, nekuti vazhinji mhando. More ruzivo nezvazvo uchaverenga mumabhuku histology zvakanaka.
