Kunyanya, mumuviri wemunhu mumwe nomumwe kune chikwata chechipiri chinonzi ureter. Muchitarisiko, iyo ipurasitiki yakareba, iyo yakareba isingasviki 30 cm, uye yakareba - kubva 4 kusvika ku7 mm. Muchikamu chino tichakutaurira kuti nei vanonyorera vachidikanwa, chinangwa chavo chii, uye chinoshanda chimiro ichi chinoita.
Maitiro eurevere muvakadzi nevarume
Ureters mumuviri wevanhu vevakomana nemukadzi vanobva ku renal pelvis. Uyezve, idzi tubhu dzinowira shure kwe peritoneum uye dzinosvika parusvingo rwechidzitiro, kuburikidza kwavanopinda mumutungamiri oblique.
Rusvingo rwemutevedzeri mumwe nomumwe rine zvikamu zvitatu:
- outer shell, ine zvibatanidza zvigunwe;
- muscular layer;
- iyo mucous membrane yakavhara ureter kubva mukati.
Iyo yakareba yehutachiona yakakosha uye inogona kusiyanisa zvakanyanya munzvimbo dzakasiyana. Saka, mumutauro wega wega munhu mumwe nomumwe ane zvinyorwa zvinyorwa zvinyorwa zvechikamu ichi chakabatanidzwa munzvimbo dzinotevera:
- munzvimbo yekushandura kwemazino epamusoro mukati mekureta;
- kusati kwabuda kwechiremba kusvika kumucheto maduku;
- mune dzimwe nzvimbo mudiki mapepa kana pasi rose;
- Pamberi pemusuo wega yega yega muchipinda.
Kureba kwechimiro chevanhu vakasiyana-siyana kunogonawo kusiyanisa, zvichienderana nehutano, makore uye zvinhu zvakasiyana-siyana zvevanhu.
Nokudaro, ureter yevakadzi inowanzomira 20-25 mm shopter kupfuura yevarume. Muchikamu chiduku muvakadzi vakanaka iyi tube inomanikidzwa kuvhara nhengo dzomukati dzepabonde, saka dzine nzira yakasiyana.
Pakuvamba, vakadzi vanoita ureters vanopfuura pamucheto wakasununguka we mavha mavari, uye ipapo pamwe nechepamusoro pemvura yakakura yechibereko. Uyezve, aya mavhapiti ari pamwe chete nekuputika oblique kupinda muchirwere mumunharaunda pedyo nemudzimai, asi pachisanganiswa muscular sphincter inoumbwa.
Basa rekureka mumuviri womunhu
Basa guru rinoshandiswa nevanoita ndeyekutakura kwemuti kubva kune renal pelvis kusvika kumucheka. Kuvapo kwemisero yakadzika murusvingo rwechigunwe ichi kunobvumira kuti igare ichichinja hupamhi hwayo pasi pekumanikidzwa kwemuti unoyerera mukati memukatikati mukati mehubhu, semugumisiro wekuti "unopinza" mukati. Uyezve, urinha haigoni kudzoka shure, sechikamu chemukati mukati mechidzara chinoshanda sevhavha uye fuse.
