Uhlelo urinary

uhlelo urinary wenza umsebenzi zisusa ubuthi, okungafunwa, compounds eziyingozi emzimbeni, ngenkathi sigcina lemali edingekile nosawoti kanye lamanzi esiphethu. Lokhu into yaqaphela ngokwakha e izinso e umchamo ivolumu ezithile futhi ngesikhathi emakamu ezithile.

Isakhiwo uhlelo urinary.

isakhiwo sayo siqukethe izitho ezikhiqiza umchamo (izinso), kanye deducing umchamo lokuqoqa excreted (esinyeni, urethra, ureter).

Izinso zitholakala esikhaleni ngemuva peritoneum nhlangothi zombili yomgogodla, kukhona ngesimo ubhontshisi. I izinso kwesokunxele lisetudlwana kuka kwesokudla. Emaphethelweni engaphezulu kuphela yomzimba pair oseduze nomgogodla, phansi - bakude.

Ngo izinso ukuchaza isigxobo aphansi kanye engenhla, onqenqemeni kwangaphakathi futhi yangaphandle. Maphakathi onqenqemeni engaphakathi esangweni elise (ushona). Ngabo, igunya kuhlanganisa izinzwa nokuvaleka kwemithambo, ureters zitholakala, lymphatics, eVienna. I iqoqo izakhi idatha obumba pedicle kwezinso.

Adipose capsule igobolondo kanye siqu zezinzwa izicubu fascia yayo azungeze izinso ngamunye. Esikhathini ketshezi izinso siqukethe izingqimba ezimbili - ngobuchopho cortex. Eyokuqala imelelwa nambili - amayunithi nanhlanu simise Isigaxa. Zibizwa ngokuthi amaphiramidi. izidakamizwa Cortical engena phakathi imibhoshongo angomakhelwane. ungqimba Cortical has a ukushuba amamilimitha angu ezine kuya nantathu.

uhlelo urinary has izindlela zokulawula eziningana.

Inani lamanzi eziqukethwe umzimba kuthinta lokuhlushwa umchamo. Isamba ngokweqile amanzi ikhuthaza okusithiyayo wokukhulula pituitary hormone antidiuretic (adh), ukulawula ukumuncwa usawoti namanzi. Lapho amanzi enganele ebucayi ujabule imfundo ekhethekile (osmoreceptors). Kulokhu, adh adedelwa igazi, egqugquzela reabsorption ka (reuptake) yamanzi.

uhlelo urinary yenza excretion umchamo yamanzi, usawoti, uric acid, urea. Ukwabiwa ncenye lokukhicitwa ukudlula emaphashini, isikhumba, amathumbu, izindlala salivary Nokho, esikhundleni izinso abakwazi.

Ukwakheka umchamo, kuhlanganise isinyathelo okufika uketshezi negazi, uketshezi futhi reabsorption, wenza nephrons (izingxenye ephambili izicubu kwezinso). nephron ngalinye izinso (Malpighian) ithole ukuhlinzeka inqubo ehlelekile, futhi Amapayipi urinary. Taurus imelelwa isitsha double-ngodonga hemispherical. Igebe phakathi kwezindonga zawo ehlanganiswa capillary glomerulus. Kusukela slot futhi iza tubule.

ingcindezi Intravascular (70-90 mm. HG. V.) Uthuthukisa kokuziphatha engxenyeni liquid igazi phakathi nephron capsule. Le nqubo ibizwa ngokuthi gqwa ketshezi leaked, ngokulandelana, ubizwa ngokuthi "filtrate" (umchamo okuyinhloko).

uhlelo urinary yakha filtrate ehlanganisa ngokuyisisekelo yamanzi. umchamo eyinhloko lokuhlushwa ongaphakeme izinto yamangqamuzana cishe iyafana ukuthi plasma. Lapho ekugqugquzeleni filtrate we tubules, ukubunjwa yayo kushintsha njalo ngenxa kuba umchamo sokugcina. Umchamo ivolumu ngokwesilinganiso amalitha eyodwa nengxenye ngosuku.

uhlelo urinary sihlanganisa e oyiyo esinyeni. Lokhu umzimba wenza umsebenzi ekuqongeleleni umchamo. Udonga umzimba elinamandla imisipha emgodleni. Ngokunciphisa ngevolumu ingaphakathi bubble yayo liyancipha. Esikhathini orifices ureteral, kuvulwa engaphakathi urethra kukhona sphincter (detrusor). Bona alawule ukugeleza umchamo.

Ukuze phansi esinyeni amashubhu kufanelekile (ureters).

Excretion of umchamo ngokusebenzisa urethra, kusale esinyeni.
