\u0130nsan b\u00f6bre\u011finde idrar olu\u015fumunda s\u00fcz\u00fclme,geri emilme ve salg\u0131lama evreleri vard\u0131r.
\n1.S\u00fcz\u00fclme :
\nY\u00fcksek kan bas\u0131nc\u0131 etkisiyle glomerulus k\u0131lcal damarlar\u0131ndan bowman kaps\u00fcl\u00fcne amino asitler,glikoz,inorganik maddeler,\u00fcre ,\u00fcrik asit ve su ge\u00e7er.Bu olaya s\u00fcz\u00fclme denir.S\u00fcz\u00fclme s\u0131ras\u0131nda ATP harcanmaz.B\u00f6breklerde \u00fcre yeterince s\u00fcz\u00fclmez ise kanda \u00fcre miktar\u0131 artar buna \u00fcremi hastal\u0131\u011f\u0131 denir.So\u011fuk havalarda glomerulus k\u0131lcallar\u0131nda b\u00fcz\u00fclme ger\u00e7ekle\u015fti\u011fi i\u00e7in s\u00fcz\u00fclme h\u0131z\u0131 ve miktar\u0131 artar.
\n2.Geri emilme :
\nGlomerulustan bowman kaps\u00fcl\u00fcne s\u00fcz\u00fclen s\u0131v\u0131n\u0131n hepsi d\u0131\u015far\u0131ya at\u0131lmaz. S\u00fcz\u00fcnt\u00fc i\u00e7inde bulunan su,glikoz,amino asit,inorganik tuzlar\u0131n nefron kanallar\u0131ndaki h\u00fccrelere al\u0131nmas\u0131na geri emilim denir.Geri emilen maddeler nefron kanallar\u0131n\u0131 saran k\u0131lcal damarlara geri verilir.
\nProksimal t\u00fcpde geri emilme :Su ozmoz ile,glikoz ve amino asitlerin t\u00fcm\u00fc ,vitaminler,amonyum,Na,CI,HCO aktif ta\u015f\u0131ma ile geri emilir.Hidrojen iyonlar\u0131da yo\u011funlu\u011fa ba\u011fl\u0131 olarak aktif veya pasif olarak geri emilir.
\nHenle kulpunda geri emilme : Klor iyonlar\u0131 aktif ta\u015f\u0131ma ile geri emilirken, sodyum iyonlar\u0131 da pasif olarak geri emilir.Henle kulpunun \u00e7\u0131kan kolundan su geri emilmez.Henle kulpu idrardaki suyun azalmas\u0131n\u0131 sa\u011flar.Bu nedenle \u00e7\u00f6l hayvanlar\u0131nda henle kulpu daha uzundur.
\nDistal t\u00fcp : Su ve sodyum geri emilimi devam eder.Suyun geri emiliminin tamamland\u0131\u011f\u0131 k\u0131s\u0131md\u0131r.Geri emilen su miktar\u0131 Antidi\u00fcretik hormonun (Vazopressin) etkisi ile sa\u011flan\u0131r.Bu hormon distal t\u00fcp ve idrar toplama kanal\u0131na etki ederek geri emilimi sa\u011flar.Ayr\u0131ca Distal t\u00fcpe etki eden aldosteron (Mineralkortikoidler) hormonu da minarel ve tuz miktar\u0131n\u0131 dengede tutar. Distal t\u00fcp \u00fcreyi ge\u00e7irmedi\u011fi i\u00e7in,\u00fcre geri emilmez.Parat hormun distal t\u00fcpden Ca geri emilimini sa\u011flar.
\nSa\u011fl\u0131kl\u0131 ki\u015filerde glikoz ve amino asitlerin tamam\u0131,suyun % 99\u2019u,sodyum iyonlar\u0131n\u0131n % 99.5\u2019i,\u00fcrenin % 50\u2019si,tuzun %98\u2019i geri emilir.
\nHer maddenin kandaki normal de\u011ferine e\u015fik de\u011fer denir.
\n3.Salg\u0131lama :
\nS\u00fcz\u00fclme ile bowman kaps\u00fcl\u00fcne ge\u00e7emeyen maddeler, k\u0131lcal damarlardan aktif ta\u015f\u0131nma ile kanalc\u0131\u011fa geri geri verilir.Bu olaya salg\u0131lama veya aktif bo\u015falt\u0131m denir.Amonyak,hidrojen ve potasyum iyonlar\u0131 ve \u00e7e\u015fitli ila\u00e7lar kanalc\u0131klara aktif bo\u015falt\u0131m ile ge\u00e7irilir. <\/p>\n","protected":false},"excerpt":{"rendered":"
