\u2022 Salg\u0131lad\u0131klar\u0131 maddeleri do\u011frudan kana veren bezlere \u201ci\u00e7 salg\u0131 bezleri\u201d denir. \u0130\u00e7 salg\u0131 bezleri kandan ald\u0131klar\u0131 maddelerden bir tak\u0131m maddeler yaparlar. Bu maddeler kan yoluyla organlara da\u011f\u0131larak, organlar\u0131n birbiri ile uyumlu \u00e7al\u0131\u015fmas\u0131n\u0131, v\u00fccudun geli\u015fmesini, beslenmeyi, b\u00fcy\u00fcmeyi, \u00fcremeyi ve ruhsal hayat\u0131 d\u00fczenler. \u0130\u00e7 salg\u0131 bezlerinin \u00e7\u0131kard\u0131\u011f\u0131 bu maddelere \u201chormon\u201d ad\u0131 verilir. Hormonlar ve bunlar\u0131 salg\u0131layan i\u00e7 salg\u0131 bezlerinin olu\u015fturdu\u011fu sisteme \u201cendokrin sistemi\u201d denir. V\u00fccudumuzdaki organ ve sistemlerin d\u00fczenli ve uyumlu \u00e7al\u0131\u015fmas\u0131nda sinir sistemi ile endokrin sistemi birlikte g\u00f6rev yapar. Ba\u015fl\u0131ca i\u00e7 salg\u0131 bezleri hipofiz, epifiz, tiroit, b\u00f6brek \u00fcst\u00fc bezi, pankreas ve e\u015feysel bezlerdir.
\n\u2022 Hipofiz ve Epifiz Bezleri :
\nHipofiz bezi, beynin taban\u0131nda hipotalamusun alt\u0131nda yer alan nohut b\u00fcy\u00fckl\u00fc\u011f\u00fcnde bir bezdir. G\u00f6revi di\u011fer bezlerin \u00e7al\u0131\u015fmas\u0131n\u0131 d\u00fczenlemek ve onlar\u0131 denetlemektir. Epifiz bezi, beynin arka k\u0131sm\u0131nda mercimek b\u00fcy\u00fckl\u00fc\u011f\u00fcnde bir bezdir. Bu bezin g\u00f6revi tam olarak bilinememekle birlikte, \u00fcreme organlar\u0131n\u0131n geli\u015fmesini kontrol ederek, d\u00fczenli \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flad\u0131\u011f\u0131 kabul edilmektedir. Hipofiz ve epifiz bezlerinin salg\u0131lad\u0131\u011f\u0131 hormonlar v\u00fccudun b\u00fcy\u00fcmesi ve geli\u015fmesini sa\u011flar. Bu bezlerin fazla \u00e7al\u0131\u015farak fazla hormon salg\u0131lamas\u0131 \u201cdevlik\u201d, az \u00e7al\u0131\u015fmas\u0131 \u201cc\u00fccelik\u201d ad\u0131 verilen anormal geli\u015fmeler g\u00f6r\u00fcl\u00fcr.
\n\u2022 Tiroit Bezi :
\nTiroit bezi, g\u0131rtla\u011f\u0131n alt\u0131nda soluk borusunun iki yan\u0131nda yer al\u0131r. \u0130\u00e7 k\u0131sm\u0131nda d\u00f6rt tane k\u00fc\u00e7\u00fck bez vard\u0131r. Bu bezlere \u201cparatiroit\u201d denir. Tiroit bezi \u201ctiroksin\u201d ad\u0131 verilen hormonu salg\u0131lar. Bu hormon v\u00fccut metabolizmas\u0131n\u0131 ve zihinsel ve bedensel geli\u015fmeyi sa\u011flar. Bu hormonun az salg\u0131lanmas\u0131 zeka gerili\u011fine, c\u00fcceli\u011fe, yorgunlu\u011fa ve deri kurumas\u0131na sebep olur. Fazla salg\u0131lanmas\u0131 ise terlemeye, kan bas\u0131nc\u0131n\u0131n artmas\u0131na ve sinirlili\u011fe sebep olur. \u0130yot olmaks\u0131z\u0131n tiroksin hormonu salg\u0131lanamaz. V\u00fccuda yeterince iyot al\u0131nmad\u0131\u011f\u0131nda hipofiz bezi tiroit bezini uyararak tiroit bezinin a\u015f\u0131r\u0131 \u00e7al\u0131\u015fmas\u0131na ve hacmini art\u0131rmas\u0131na sebep olur. Tiroit bezinin b\u00fcy\u00fcmesi ile \u201cguatr\u201d ad\u0131 verilen hastal\u0131k meydana gelir. Bu hastal\u0131k ilk a\u015famada A vitamini kullan\u0131larak, ileri hallerde ameliyatla tedavi edilebilir. Paratiroit hormonu \u201ckalsitonin\u201d hormonu salg\u0131lar. Bu hormon kandaki kalsiyum miktar\u0131n\u0131 kontrol ederek, kemiklerin sertle\u015fmesini sa\u011flar.
\n\u2022 B\u00f6brek \u00dcst\u00fc Bezleri :
\nHer iki b\u00f6bre\u011fin \u00fcst\u00fcnde, b\u00f6breklere yap\u0131\u015f\u0131k fasulye b\u00fcy\u00fckl\u00fc\u011f\u00fcnde bezlerdir. D\u0131\u015fta kabuk, i\u00e7te ise \u00f6z b\u00f6lgesi vard\u0131r. Bezlerin kabuk k\u0131sm\u0131 \u201ckortizol\u201d hormonu, i\u00e7 k\u0131sm\u0131 ise \u201cadrenalin\u201d hormonu salg\u0131lar. Kortizol, proteinlerin karbonhidratlara d\u00f6n\u00fc\u015f\u00fcm\u00fcn\u00fc sa\u011flar. Adrenalin, kandaki karbonhidrat metabolizmas\u0131n\u0131 d\u00fczenler. Korku ve heyecan halinde adrenalin hormonu fazla salg\u0131lan\u0131r.
\n\u2022 Pankreas :
\nKar\u0131n bo\u015flu\u011funda, midenin alt\u0131nda hem i\u00e7 salg\u0131 hem de d\u0131\u015f salg\u0131 bezidir. Alfa ve beta h\u00fccrelerinden olu\u015fur. Alfa h\u00fccreleri \u201cglukagon\u201d hormonu, beta h\u00fccreleri ise \u201cins\u00fclin\u201d hormonu salg\u0131lar. Bu iki hormon beraber \u00e7al\u0131\u015farak kandaki \u015feker miktar\u0131n\u0131 ayarlarlar. Glukagon hormonu kanda \u015feker d\u00fc\u015ft\u00fc\u011f\u00fcnde karaci\u011ferden kana \u015feker ge\u00e7mesini sa\u011flar. \u0130ns\u00fclin ise kandaki \u015fekerin h\u00fccrelere ge\u00e7mesini sa\u011flar. Yani kan \u015fekerini d\u00fc\u015f\u00fcr\u00fcr. Ayr\u0131ca ins\u00fclin yemeklerden hemen sonra fazla \u015fekeri akci\u011fere ge\u00e7irerek depolar. Bu hormonlar\u0131n yeterli salg\u0131lanamamas\u0131 halinde \u201c\u015feker hastal\u0131\u011f\u0131\u201d meydana gelir. Bu hastal\u0131k v\u00fccuda ins\u00fclin hormonu verilerek tedavi edilebilir.
\n\u0130nsanda y\u00f6netimi ve iletimi sa\u011flayan sistemdir. V\u00fccudumuzdaki organ ve sistemlerin uyumlu \u00e7al\u0131\u015fmas\u0131nda i\u00e7 salg\u0131 bezleri de g\u00f6rev yapar.<\/p>\n","protected":false},"excerpt":{"rendered":"
