Uhlelo excretory yomuntu: esifushane futhi amnandi

Inani ngayo ukudla esikudlayo ukuze empilweni yami, amashumi amathani, inani ukusetshenziswa uphuzo - ukubaluleka oda efanayo. Kuze kube manje, akekho wavele, nakuba isihloko uyohlale ihlaya. Iqiniso lokuthi yonke udle sihamba polycycle elihlobene ne Milling kanye nenguquko zamakhemikhali. Futhi kuthatha imfucuza womuntu excretory uhlelo. Ukuziletha kulesi sihloko kuyoba encane. Uzodinga 4 Amakhasi: mayelana izinso, emaphashini, ikholoni isibindi, isikhumba.

Izinso - abasebenzi elikhulu umzimba todvwa: 70% wenani imfucuza okukhipha yibo. Basebenza ne ezinobuthi kakhulu, okuyizinto somzimba evamile - imikhiqizo wamaprotheni umzimba: creatinine, urea kanye uric acid. Basuke zihilelekile ukulawulwa uketshezi, nosawoti, nosizo ukuqeda izinto angaphandle. Izinso yokukhosela ephephile kuzo zonke izinhlangothi: ubunjalo ivikela lezi zitho kohlelo excretory yomuntu. Uma omunye izinso ogulayo, wesibili uyangenelela umsebenzi.

umkhiqizo izinso - umchamo - Yenziwe igazi, nakuba has hhayi idumela wekuvana lakamuva. Nakuba abase-India, kuze kube uketshezi iphathwa ngenhlonipho. Umchamo uba lutho lokho bekungeke kube egazini. Izinso ethathwe egazini labo bonke ezingadingekile, futhi ushiye izakhi zomzimba. Igazi ku izinso siphela 2 ukuguqulwa esiteji. Okokuqala kuthatha eziningi, ngisho ewusizo ke ukusivumela kwesokudla emuva. Ukuze inqubo yokuqala kufanele ibe ingenaso amandla, eyesibili kakhulu izindleko ngakho izinso kancane ibusa 10% e-oxygen ayeyile umzimba. Ngakho kakhulu womuntu excretory uhlelo budinga nomoya-mpilo.

Lapho okukhipha umchamo, lo mkhulu iba imithambo yegazi, futhi okuphambene nalokho. Kanye nenani uketshezi imithambo yegazi yomuntu ingcindezi kuncike ngokuqondile. Uma ingcindezi lehla - ngisho zokuhlunga ngeke kwenzeke, futhi uma ngizwa ingcindezi mkhulu kakhulu, nephrons (fukntsionalnye amayunithi) ngeke bakamalalahlengezela behluleka. Ukuze bazivikele, izinso ukukhiqiza renin. Lokhu i-hormone ikuvumela ukulungisa ingcindezi. Kusukela izinso ezibucayi kudingeka oksijini, zikhiqiza erythropoietin, elibangela umnkantsha ukudala abomvu egazi ashaye --mpilo egazini. Ngakho ngaso sonke isikhathi uma ungenawo umoya ngokwanele ngesikhathi ebaleka, uyazi ukuthi izinso ukukhiqiza ngalesi sikhathi, isiginali phezu ukukhiqizwa kwamangqamuzana egazi abomvu.

Umchamo phansi kwesinye, ukuthi lapho agcinwe kuze kube ngomzuzu lapho umuntu omdala enquma uthulule ke. A womntwana inqubo ephethe emgogodleni, kodwa eminyakeni emibili uvuthwe izikhungo ezifanele ngobuchopho ingane ifunda potty. Nokho, ngisho nomuntu omdala ungalahlekelwa ukulawula ukuchama inqubo uma umchamo esinyeni ukuba abangaphezu kuka-500 ml. Ngeke kubekezelelwe isikhathi eside njalo: yokujama tsi umchamo kanye kumiswa amatshe.

Uma izinso behluleka, izinkinga eziningi ongaxazulula isikhumba. Ayahwamuka kuze kube ilitha ngosuku. Uma izinso ugula, umjuluko kungaba unuka njengetekisi umchamo. Futhi ezishisa kakhulu zikhipha izinhlayiyana zokukhanya izidakamizwa olubonakalayo - kuhlanganise 400 ml amanzi.

Human excretory simiso sihlanganisa ingemuva. Lihlobene nokubhekana ubuso kwesibindi, ngoba iningi anobuthi indle eyatholakala kusukela Bile, futhi Bile kusukela kwesibindi yakha "babanjwa" izinto kusukela egazini. Nokho, ukuze ukhiphe indle lula - ukusebenza imisipha besisu namathumbu kanyekanye. I ingemuva uthululwa ezikhathini evamile ngosuku, ngokwesilinganiso, omunye wethu ohamba 150g. Izinso lwenyanga uboniswa cishe 45 amalitha umchamo. Ngakho ukuthi umthwalo lezi zindikimba eside.

Human excretory Uhlelo lusebenza kahle, uma kukhona izinkinga kwelinye sitho, nabanye bathathwa umsebenzi womunye umuntu. Uma isibindi ogulayo noma umsebenzi izinso, amaprotheni imikhiqizo umzimba okukhipha amaphaphu isikhumba, futhi uma isibindi akakwazi ukubhekana umzimba elithwala umoya-mpilo imfucuza, kuyobe zenziwe nezinso.
