\u0097 Kar\u0131nc\u0131klar ve kulak\u00e7\u0131klar aras\u0131nda kapaklar vard\u0131r. Bu kapaklar sadece tek y\u00f6ne do\u011fru a\u00e7\u0131l\u0131r. Kapaklar, kalbin i\u00e7indeki kan ak\u0131\u015f\u0131n\u0131n tek y\u00f6ne do\u011fru olmas\u0131n\u0131 sa\u011flar, kan\u0131n geriye do\u011fru akmas\u0131n\u0131 engeller.<\/p>\n

\u0097 Bu beyaz h\u00fccreler, v\u00fccudun mikroplara kar\u015f\u0131 savunmas\u0131nda g\u00f6revlidirler.<\/p>\n
\u0097 Kanda bulunan bir ba\u015fka h\u00fccre kan pulcuklar\u0131d\u0131r.<\/p>\n
\u0097 Kan pulcuklar\u0131, boyutunun \u00e7ok k\u00fc\u00e7\u00fck olmas\u0131 nedeniyle mikroskopta g\u00f6r\u00fclemeyebilir.<\/p>\n

\u0097 Kirli kan, toplardamar ile kalbin sa\u011f kulak\u00e7\u0131\u011f\u0131na gelir. Kar\u0131nc\u0131k ve kulak\u00e7\u0131klar aras\u0131ndaki kapak, kirli kan\u0131n kulak\u00e7\u0131\u011fa gelmesi ile a\u00e7\u0131l\u0131r ve kan sa\u011f kulak\u00e7\u0131ktan sa\u011f kar\u0131nc\u0131\u011fa g\u00f6nderilir.<\/p>\n
\u0097 Sa\u011f kar\u0131nc\u0131k, temizlenmesi i\u00e7in kan\u0131 akci\u011ferlere yollar. Akci\u011ferlerde temizlenen kan, kalbin sol kulak\u00e7\u0131\u011f\u0131na gelir. Aradaki kapak yine a\u00e7\u0131l\u0131r ve kan sol kar\u0131nc\u0131\u011fa ge\u00e7er.<\/p>\n
\u0097 Sol kar\u0131nc\u0131k kan\u0131 v\u00fccuda pompalar.<\/p>\n
KAN GRUPLARI: Kan gruplar\u0131 ki\u015fiye \u00f6zg\u00fc olan bir \u00f6zelliktir. D\u00f6rt \u00e7e\u015fit kan grubu bulunmaktad\u0131r. Bunlar; A, B, AB ve 0 gruplar\u0131 olarak adland\u0131r\u0131l\u0131r. Kan gruplar\u0131n\u0131n adland\u0131r\u0131lmas\u0131, kan\u0131n i\u00e7inde bulunan proteinlere g\u00f6re yap\u0131l\u0131r.<\/p>\n
\u0097 Kana ihtiyac\u0131 olan insanlara kan verilmesine kan nakli denir. Kan nakli, kan gruplar\u0131n\u0131n uygunlu\u011funa g\u00f6re yap\u0131lmal\u0131d\u0131r.<\/p>\n
\u0097 Her kan grubu kendi i\u00e7erisinde birbirinden kan al\u0131p verebilir.<\/p>\n
\u0097 S\u0131f\u0131r ve AB kan gruplar\u0131 farkl\u0131 bir \u00f6zelli\u011fe sahip olarak bilinmektedir.<\/p>\n
\u0097 S\u0131f\u0131r kan grubu, di\u011fer t\u00fcm kan gruplar\u0131na kan verebildi\u011fi i\u00e7in genel verici, AB kan grubu ise di\u011fer t\u00fcm kan gruplar\u0131ndan kan alabildi\u011fi i\u00e7in genel al\u0131c\u0131 olarak adland\u0131r\u0131l\u0131r. Oysa g\u00fcnl\u00fck ya\u015famda b\u00f6yle bir uygulama yoktur. Yani hastanede AB kan grubundan bir insandan al\u0131nan kan A, B ya da s\u0131f\u0131r kan grubu insanlara verilmez.<\/p>\n
\u0097 Farkl\u0131 kan gruplar\u0131 aras\u0131nda kan al\u0131\u015f veri\u015fi bir\u00e7ok sa\u011fl\u0131k problemine, hatta \u00f6l\u00fcmlere yol a\u00e7abilir.<\/p>\n
\u0097 Kan gruplar\u0131 tayin edilirken bir de Rh fakt\u00f6r\u00fc belirlenir. Kan gruplar\u0131 Rh fakt\u00f6r\u00fcyle beraber adland\u0131r\u0131l\u0131r. Rh fakt\u00f6r\u00fc baz\u0131 bireylerde Rh pozitif, baz\u0131 bireylerde ise Rh negatiftir.<\/p>\n
\u0097 Kan gruplar\u0131yla beraber Rh fakt\u00f6r\u00fc de kan naklinde \u00f6nemlidir.<\/p>\n","protected":false},"excerpt":{"rendered":"
