The Urinary maitiro

Urinary hurongwa anoita mashandiro dzichibvisa tsvina, vasingadiwi, anokuvadza yeimwe mumuviri, apo kuramba anodiwa huwandu chicherwa munyu uye mvura. chinhu ichi chaitwa nokuda dzichiumbwa itsvo dziri weti vamwe vhoriyamu uye pane imwe pfungwa.

Nemamiriro nezvezvimwe zvinetso zvedundira.

mamiriro ayo ine nhengo kuti vabereke weti (itsvo), uye deducing rokuunganidza weti yabudiswa (dundira, urethra, ureter).

Itsvo dziri mu seri peritoneum pamusoro mativi ose nomuzongoza, vari muchimiro nebhinzi. The akasiya itsvo iri zvishoma kupfuura zvakanaka. Okumusoro micheto vaviri muviri pedyo nomuzongoza, pasi - vari kure.

In itsvo kutsanangura yakaderera uye yokumusoro danda, yomukati dzokunze mucheto. Pakati yomukati kumucheto pasuwo riri (kudzamisa). Kuburikidza navo, simba kunosanganisira tsinga uye arteries, ureters dziri, lymphatics, Vienna. The akagadzirwa umboo zvinhu achiumba renal pedicle.

Adipose Kamudzira goko uye yayo connective zvinyama fascia zvinovakomberedza mumwe itsvo. Muna itsvo fuma chinosanganisira maviri akaturikidzana - uropi uye cortex. Wokutanga chinomiririrwa gumi - gumi inokwana zviyero ari cône chimiro. Inonzi mapiramidhi. Cortical fuma seeps pakati yakavakidzana mapiramidhi. Cortical rukoko ane Ukobvu mana nenhatu millimeters.

Urinary maitiro ane pamutemo zvigadziriswe dzakawanda.

Uwandu mvura yaiva mumuviri kunokanganisa wevasungwa kuti weti. An kunyanya kuwanda mvura kunoita chinovhiringidza pamusoro pituitary kwebhuku pakati antidiuretic kemikari (ADH), nokudzora Absorção de Água munyu uye mvura. Kana mvura kukwana vasanonoka kufara dzidzo chaiyo (osmoreceptors). Muchiitiko chino, ADH akasunungura kupinda ropa, inosimudzira reabsorption ose (reuptake) emvura.

Urinary hurongwa anoita weti excretion mvura, munyu, uric acid, urea. The yavaive yenhengo izvi anobudiswa uye kuburikidza mumapapu, ganda, ura, mumasero mate, zvisinei, kutsiva itsvo havagoni.

Paumbwe weti, kusanganisira danho inonzwika apo nemvura neropa, secretion uye reabsorption, akaita nephrons (constituent zvikamu renal tishu). Mumwe nephron vari itsvo (Malpighian) mhuru kugovera mupise kwacho, uye Urinary ducts. Taurus inomiririrwa miviri akavakirirwa hemispherical mbiya. Musiyano uri pakati pamasvingo aro kwakafukidza rirambe richibvira glomerulus. Kubva slots kwasvikawo tubule.

Intravascular kumanikidzwa (70-90 mm. HG. V.) Rinokurudzira infiltration nemvura chikamu ropa mukati Kamudzira nephron. Izvi anonzi inonzwika apo leaked mvura, ukuwo, anonzi "filtrate" (chikuru weti).

Urinary Hurongwa unoumba munhu filtrate rinosanganisira chezvematongerwe mvura. chikuru weti wevasungwa yakaderera samolecular zvinhu ndiyo inenge kufanana kuti plasma. Kana kutsigira filtrate pakati tubules, ayo akafanana ari dzichichinja somugumisiro yava yokupedzisira weti. Weti vhoriyamu iri avhareji marita rimwe nehafu pazuva.

Urinary maitiro zvinosanganisira wayo maumbirwo dundira. muviri uyu anoita mashandiro kuunganidza weti. The muviri Rusvingo simba tsandanyama mumuhara. Akaroromesawo Vhoriyamu ayo mhango sefuro kunodzikira. Muna ureteral orifices, romukati Huro urethra vari sphincter (detrusor). Ivo waidzora chekubuda weti.

Kusvikira pasi dundira vadzidza sepombi (ureters).

Excretion kuti weti nokupira urethra, kusiya dundira.
