Iyoweti Iyo mvura inoumbwa nemvura nezvinhu zvakaparadzaniswa nemuviri, uye izvo zvine mabasa akabatanidzwa nekubviswa kwezvinhu zvisina basa zvemuviri, kana zvine chekuita ne electrolyte control, BP uye acid-base balance. Weti inovigwa neitsvo, inochengetwa mudundira, uye inobviswa panguva yekuita weti..

Hunhu hunhu: ruvara uye hwema

Pakati peakakosha maitiro eweti ndeyayo ruvara, inosanganiswa nehuwandu hwemvura irimo mairi: nepo iwo muviri wakadya mvura yakawanda unenge uine weti yakajeka, mumitumbi yakawanda isina mvura zvakajairika kuti itsvo dzichengete mvura mumuviri, zvichikonzera kuti weti ive neruvara yero yakasimba.

Pakupedzisira weti inogona kuve nerudzi rweatypical, iyo inogona kunge iri nekuda kwezvinhu zvisina kunaka (sekumwa kwezvikafu zvine mavara) kana nekuda kwezvirwere zvehurongwa. Kana zviri zvakajairika weti haina chero munhuhwi, asi pane dzimwe nguva inogona kuva nekunhuhwirira kusingajairike: seruvara, inogona kunge iri nekuda kwezvakanaka kana zvidiki nyaya, kana kune zvakanyanya kana zvishoma zvakanyanya zvirwere.

Ko weti inogadzirwa nei?

Muviri unowanzo bvisa marita nehafu weti pazuva. Iyi nhamba, zvisinei, inonyatsotsanangurwa kana uchitarisa kuumbwa kweweti:

95% weti yakaumbwa nemvura, nepo 2% ichiumbwa nemamineral salt (se chloride, phosphates, sulfates, ammonia salts) uye 3% organic zvinhu (urea, uric acid, hippuric acid, creatinine). Urini ndechimwe chezvinhu zviviri zvakakosha zvekurasikirwa nemvura kubva mumuviri, pamwe nedikita.

Weti inogadzirwa sei?

Kuumbwa kweweti inzira ine matanho matatu:

1. Kuchenesa: Ropa rinotakurwa neanehukama arteriole rinosvika kune glomerulus, uye iyo solute yeplasma inodarika nepama capillaries nekumhanya kwazvo. Mukati me glomerulus, tsvina yemetaboli inosvinwa, uye zvinovaka muviri zvidiki zvinoraswa: kufamba kwehuwandu hwemvura kunopa kuumbwa kwemvura, inonzi glomerular filtrate.
2. Tubular reabsorption: Iyo yakasvinwa mvura inofambira mberi kuburikidza neiyo renal tubules, uye ipapo zvimwe zvezvinhu zvinodzoswazve zvoiswa muropa zvakare. Zvimwe zvezvinhu zvakadzoreredzwa imvura, sodium, glucose, phosphate, potasium, amino acids uye calcium.
3. Kubuda kweTubular: Kubva muplasma yeropa kusvika kune iyo uriniferous space, chikamu chakakura chezvinhu zveropa chinotakurwa, nepo marara acho achigadzirwa kubva kumatubular capillaries kuenda kune lumen yetubule, munzvimbo iri kure.

Kana ichinge yaumbwa, mvura yacho inosvika pombi yekunhonga uko chinhu choga chayinogona kusanganisa imvura yakati wandei, nekudaro haina kutariswa seimwe chikamu chekuumbwa. Nekudaro, ndiyo nzvimbo iyo iyo mvura inowana zita rekuti weti, uye inoendeswa kune weti bladder, uko kwainozochengeterwa kusvikira weti Reflex yaitika.

Weti kuongorora

Nekuda kwehunhu hweweti ndeyekuti ongororo dzinogona kuitwa dzekuumbwa kwayo dzinobatsira kwazvo- Nemupepa wakakosha webepa, bvunzo inogona kuitwa nekukasira inoratidza kana paine chero zvigadzirwa zvisina kujairika mumuti weti, zvakajairika zvacho shuga, mapuroteni kana ropa.

Zvirwere zvakaita se cystitis, chirwere chemoyo, kana zvakasiyana weti kana itsvo Zvinogona kuwanikwa kuburikidza nerudzi urwu rwekuongorora, iro zvakare rine mashandiro ekuona kushandiswa kwemimwe mishonga inobviswa kuburikidza neweti.
