Kapangidwe Kothandizira Kutaya Zinyalala za Kagayidwe ka Zinthu
Chamoyo chilichonse chimadutsa mu njira za kagayidwe kachakudya zomwe zimapanga mphamvu ndi zinthu zina zofunika kuti chikhale ndi moyo. Komabe, njira zimenezi zimapanganso zinyalala zomwe zingakhale zoopsa ngati sizichotsedwa m'thupi. Dongosolo lomwe limayang'anira kuchotsa zinyalala za kagayidwe kachakudya limatchedwa dongosolo lotulutsa zinyalala. M'nkhaniyi, tikambirana mwatsatanetsatane za kapangidwe ka zinthu zomwe zimathandiza kutaya zinyalala za kagayidwe kachakudya, makamaka mwa anthu, komanso njira zina zingapo zofunika.
Dongosolo Lotulutsa Madzi Mwa Anthu
Anthu ali ndi njira yovuta yotulutsira madzi m'thupi yomwe ili ndi ziwalo zofunika kwambiri: impso, khungu, mapapo, ndi chiwindi. Chiwalo chilichonse mwa izi chimakhala ndi ntchito yakeyake yochotsa zinyalala.
1. Impso
Impso ndi ziwalo zazikulu mu dongosolo la chimbudzi cha munthu, zomwe zimasefa magazi kuti achotse zinyalala za kagayidwe kachakudya ndi madzi ochulukirapo ndi ma electrolyte mu mkodzo. Kapangidwe ka impso komwe kamathandizira izi ndi:
– Nephron: Chigawo chaching'ono kwambiri mu impso, chomwe chimayang'anira kusefa magazi ndikupanga mkodzo. Impso iliyonse ya munthu ili ndi ma nephrons pafupifupi miliyoni imodzi.
– Glomerulus: Mitsempha yamagazi yomwe imasonkhana kumayambiriro kwa nephron yomwe imagwira ntchito ngati malo oyamba osefera. Apa ndi pomwe magazi amasefedwa kuti alekanitse zinyalala ndi zigawo zamagazi zomwe thupi limafuna.
– Ma Renal Tubules: Pambuyo posefedwa mu glomerulus, madzi otchedwa glomerular filtrate amalowa mu ma renal tubules. Apa, kuyamwanso ndi kutulutsa kumachitika, zomwe zimathandiza kuwongolera kapangidwe ka zinthu zomwe ziyenera kutulutsidwa kapena kusungidwa m'thupi.
2. Khungu
Khungu lilinso mbali ya njira yotulutsira madzi m'thupi, makamaka kudzera mu thukuta, lomwe limatulutsa thukuta. Thukuta limakhala ndi madzi, mchere, ndi urea pang'ono, zomwe zimawononga nayitrogeni. Ntchito yotulutsira madzi m'thupi la khungu ndi yofunika kwambiri pothandiza kulamulira kutentha kwa thupi ndikusunga electrolyte bwino.
3. Mapapu
Mapapu amagwira ntchito yotulutsa mpweya wa carbon dioxide, womwe ndi chinthu chonyansa chomwe chimachokera mu kupuma kwa maselo. Kudzera mu njira yopumira, mpweya wa carbon dioxide umatengedwa kuchokera m'magazi kupita ku alveoli m'mapapo kenako n’kutulutsidwa m’thupi tikamapuma.
4. Mtima
Chiwindi chimagwira ntchito yofunika kwambiri pa kagayidwe ka mafuta, mapuloteni, ndi chakudya, komanso kuchotsa poizoni m'thupi. Pa kagayidwe ka mapuloteni, chiwindi chimasintha ammonia woopsa kukhala urea, womwe umatuluka kudzera mu impso.
Njira Yotayira Zinyalala za Kagayidwe ka Zinthu
Ziwalo zinayi zotulutsa madzi zomwe zatchulidwa pamwambapa zimagwira ntchito mogwirizana pochotsa poizoni m'thupi, kusefa, ndikuchotsa zinyalala za kagayidwe kachakudya m'thupi. Izi ndi njira zazikulu zomwe zimathandizira ntchito izi:
Kusefa
Njira yaikulu yochotsera zinyalala za kagayidwe kachakudya mu impso imayamba ndi kusefa magazi mu glomerulus, komwe madzi a m'magazi, madzi ndi mamolekyu ang'onoang'ono amadutsa mu nembanemba yosefera kupita ku kapisozi ya Bowman, pomwe maselo amagazi ndi mamolekyu akuluakulu monga mapuloteni amakhalabe m'magazi.
Kubwezeretsanso ndi Kutulutsa Madzi
Mu machubu onse a impso, zinthu zoposa 99% zosefedwa zimabwereranso m'magazi kudzera mu kuyamwanso, kuphatikizapo shuga, sodium, ndi madzi. Zinthu zokha zomwe sizikufunikiranso m'thupi, monga ma ayoni ochulukirapo ndi urea, zimasungidwa ndikutulutsidwa mu mkodzo.
Kufalikira
M'mapapo, kusinthana kwa mpweya pakati pa mpweya ndi mpweya wa carbon dioxide kumachitika kudzera mu kufalikira kwa mpweya. Mpweya wa carbon dioxide wochokera m'magazi umafalikira kupita ku alveoli kuti utuluke, pomwe mpweya umapumidwa ndikufalikira m'magazi.
Kufunika kwa Mapangidwe Othandizira Potulutsa Madzi
Chigawo chilichonse mu dongosolo la chimbudzi chili ndi gawo lofunika ndipo chimathandizana kuti chitsimikizire kuti thupi limakhala bwino.
– Kusintha kwa Homeostasis: Kudzera mu kuphatikizana kovuta kumeneku kwa njira, thupi limatha kusunga mikhalidwe yokhazikika yamkati, kuthana ndi kusinthasintha kochokera ku chilengedwe chakunja, ndikusintha kupanga ndi kutaya zinthu ngati pakufunika.
– Kuwongolera Kuchuluka ndi Kapangidwe ka Madzi a M'thupi: Mwachitsanzo, impso zimathandiza pakulamulira kuchuluka kwa magazi ndi madzi a m'thupi, komanso kuchuluka kwa ma electrolyte osiyanasiyana m'thupi.
– Kusamalira Zinyalala za Kagayidwe ka Thupi: Popanda dongosolo lothandizirali, zinthu zovulaza ndi poizoni zimatha kudziunjikira m'thupi ndikuwononga maselo ndi machitidwe onse.
Mapeto
Kuchotsa zinyalala za kagayidwe kachakudya ndi njira yofunika kwambiri kuti zamoyo zonse zipulumuke, zomwe zimaphatikizapo mgwirizano wabwino wa ziwalo monga impso, khungu, mapapo, ndi chiwindi. Mapangidwe othandizira mkati mwa njira iliyonse yotulutsira zinyalalayi adapangidwa kuti atsimikizire kuti zinyalala zimachotsedwa bwino, motero kusunga homeostasis ndi thanzi lonse. Popanda machitidwe ogwirizana awa, thupi silingathe kusunga bwino mkati mwake, zomwe zingakhudze thanzi ndi magwiridwe antchito abwinobwino a chamoyo. Mbali iliyonse ya machitidwe awa ikuwonetsa zovuta ndi kukongola kwa njira zamoyo zomwe zimachirikiza moyo.
