B\u00f6brekler, \u00fcreterler ve mesaneden olu\u015fan bo\u015falt\u0131m sistemi, metabolizma s\u0131ras\u0131nda ortaya \u00e7\u0131kan at\u0131k maddelerin at\u0131l\u0131m\u0131ndan sorumludur.

Bu at\u0131klar \u00fcreterler yoluyla mesaneye ge\u00e7erek, belli aral\u0131klarla mesanede idrar olarak depolan\u0131p, periyodik olarak v\u00fccuttan at\u0131l\u0131rlar.<\/p>\n
B\u00f6brekler
\n B\u00f6brekler omurgan\u0131n her iki yan\u0131nda, kaburgalar\u0131n hemen alt\u0131nda bulunup, sa\u011f b\u00f6brek \u00fczerinde bulunan karaci\u011fer dolay\u0131s\u0131yla biraz daha a\u015fa\u011f\u0131 seviyededir. Yeti\u015fkin bir insanda her biri 130-150 gr a\u011f\u0131rl\u0131\u011f\u0131nda olan b\u00f6brekler, yumruk b\u00fcy\u00fckl\u00fc\u011f\u00fcnde, fasulyeye benzeyen bir \u00e7ift idrar yapan organd\u0131r.<\/p>\n
\u00dcreterler
\n \u00dcreterler, b\u00f6brek ile idrar torbas\u0131 aras\u0131nda bulunurlar. 25-30 cm uzunlu\u011funda, 4-7 mm \u00e7ap\u0131nda, kas liflerinden olu\u015fmu\u015f boru \u015feklinde yap\u0131lard\u0131r. B\u00f6breklerde olu\u015fan idrar bu ince borucuklar vas\u0131tas\u0131yla idrar torbas\u0131na ula\u015f\u0131r.
\n Ureter pars abdominalis ve pars pelvica olmak \u00fczere iki k\u0131s\u0131mda incelenir. Ureterin \u00fc\u00e7 yerde darl\u0131\u011f\u0131 vard\u0131r. Birinci darl\u0131k ba\u015flang\u0131\u00e7 yerinde, ikinci darl\u0131k linea terminalis\u2019i \u00e7aprazlad\u0131\u011f\u0131 yerde, \u00fc\u00e7\u00fcnc\u00fc darl\u0131k da mesaneye girdi\u011fi yerdedir (en dar yeri buras\u0131d\u0131r).<\/p>\n
Mesane (\u0130drar Torbas\u0131)
\n Mesane yo\u011fun kas liflerinden olu\u015fmu\u015f, idrar\u0131n depoland\u0131\u011f\u0131, geni\u015fleme \u00f6zelli\u011fine sahip torba \u015feklinde yap\u0131d\u0131r. Mesane doldu\u011funda mesane duvar\u0131n\u0131 olu\u015fturan kas lifleri gerilerek idrara \u00e7\u0131kma hissi uyand\u0131r\u0131r ve duvar\u0131ndaki kaslar\u0131n kas\u0131lmas\u0131 ile mesane bo\u015fal\u0131r. Kad\u0131nlarda pelvis bo\u015flu\u011funun taban\u0131nda, erkeklerde rektumun \u00f6n\u00fcnde ve prostat\u0131n \u00fczerindedir. <\/p>\n
