Kalbin olduk\u00e7a sistemli bir mekanizmas\u0131 vard\u0131r. Bu mekanizmada meydana gelen tek bir aksakl\u0131k o insan\u0131n hayat\u0131n\u0131 sona erdirebilir. Kalbin sahip oldu\u011fu mekanizmalardan en \u00f6nemlisi sa\u011f ve sol taraf\u0131nda bulunan pompalard\u0131r. Kalbin her iki taraf\u0131nda da kulak\u00e7\u0131k ve kar\u0131nc\u0131klar bulunmaktad\u0131r. K\u00fc\u00e7\u00fck pompa her iki tarafta da kulak\u00e7\u0131klard\u0131r, b\u00fcy\u00fck pompalar\u0131 ise kar\u0131nc\u0131klar olu\u015fturur. Kalbin sol taraf\u0131 temiz kan ile ilgilenir. Gelen temiz kan\u0131 organ ve dokulara ula\u015ft\u0131rmak, kalbin sol taraf\u0131nda bulunan sol kulak\u00e7\u0131k ve sol kar\u0131nc\u0131\u011fa d\u00fc\u015fer. Kalbin sa\u011f taraf\u0131 ise kirli kan ile ilgilenir. Sa\u011f kar\u0131nc\u0131k ve sa\u011f kulak\u00e7\u0131k kirli kan\u0131 temizlenmek \u00fczere akci\u011ferlere ula\u015ft\u0131rmak i\u00e7in g\u00f6rev ba\u015f\u0131ndad\u0131r.<\/p>\n
Temiz kan kalbe ula\u015ft\u0131\u011f\u0131nda \u00f6nce \u00fcst taraftaki k\u00fc\u00e7\u00fck pompaya, yani sol kulak\u00e7\u0131\u011fa dolar. Buradan alt tarafta bulunan b\u00fcy\u00fck pompaya yani sol kar\u0131nc\u0131\u011fa iletilir. Kirli kan da, yine ayn\u0131 \u015fekilde sa\u011f kulak\u00e7\u0131ktan sa\u011f kar\u0131nc\u0131\u011fa iletilir. Kalpteki her kulak\u00e7\u0131k birbirlerinden farkl\u0131 g\u00f6r\u00fcnseler de asl\u0131nda yapt\u0131klar\u0131 i\u015f ayn\u0131d\u0131r. Her biri belirli bir hedefe do\u011fru kan\u0131 iletmekle g\u00f6revlidir.<\/p>\n
Mekanizman\u0131n sistemli \u00e7al\u0131\u015fmas\u0131, bahsetti\u011fimiz bu s\u0131ral\u0131 i\u015flem nedeniyle \u00e7ok \u00f6nemlidir. Her\u015feyin s\u0131ra ile yap\u0131lmas\u0131 gerekmektedir. E\u011fer bu d\u00fczen bozulursa, kalp v\u00fccuda ya hi\u00e7 kan pompalayamayacak ya da kalbe a\u015f\u0131r\u0131 kan y\u00fcklenmesi olacakt\u0131r. Bu s\u0131ralaman\u0131n do\u011fru yap\u0131labilmesi i\u00e7in kulak\u00e7\u0131k ve kar\u0131nc\u0131klar aras\u0131nda kapaklar vard\u0131r. Bu kapaklar kan\u0131n ak\u0131\u015f y\u00f6n\u00fcne do\u011fru tek tarafl\u0131 olarak a\u00e7\u0131l\u0131rlar. Kulak\u00e7\u0131klar kas\u0131ld\u0131\u011f\u0131nda bu kapaklar a\u00e7\u0131l\u0131r ve kan b\u00fcy\u00fck pompan\u0131n yani kar\u0131nc\u0131klar\u0131n i\u00e7ine dolar. Bu i\u015flem ger\u00e7ekle\u015ftikten sonra, kan\u0131n geldi\u011fi yere geri d\u00f6nmemesi i\u00e7in kapaklar tekrar kapan\u0131r.<\/p>\n
Ana toplardamar, oksijensiz kan\u0131 bedenin sa\u011f k\u0131sm\u0131na getirir ve akci\u011fer damarlar\u0131 bu kan\u0131 akci\u011ferlere iletir. Akci\u011fer toplardamar\u0131 oksijenli kan\u0131 akci\u011ferlerden kalbin sol taraf\u0131na getirir ve aort bu kan\u0131 v\u00fccuda g\u00f6nderir. Kan\u0131n bu hareketi s\u0131ras\u0131nda kalp kapak\u00e7\u0131klar\u0131 kas\u0131larak kan\u0131n odac\u0131klar aras\u0131nda ge\u00e7i\u015fini sa\u011flar.<\/p>\n
Bu kapaklar, kalbin kar\u0131nc\u0131klar\u0131nda da vard\u0131r. Kar\u0131nc\u0131klar kas\u0131ld\u0131\u011f\u0131nda bu kapaklar a\u00e7\u0131l\u0131r ve kan\u0131n v\u00fccuda do\u011fru akmas\u0131 sa\u011flan\u0131r. Pompalama i\u015flemi durdu\u011funda ise kapaklar kapan\u0131r ve pompalanan kan\u0131n kalbe geri d\u00f6nmesi engellenir. Bizim “kalp at\u0131\u015f\u0131” olarak alg\u0131lad\u0131\u011f\u0131m\u0131z ses ise, san\u0131ld\u0131\u011f\u0131 gibi kalbin kas\u0131l\u0131p gev\u015femesi sonucunda \u00e7\u0131kan ses de\u011fildir. Kalp at\u0131\u015f\u0131n\u0131 dinlerken, asl\u0131nda bu d\u00f6rt kapak\u00e7\u0131\u011f\u0131n \u015fiddetle a\u00e7\u0131l\u0131p kapanma seslerini duyar\u0131z.<\/p>\n
Bu kusursuz sistemin sahip oldu\u011fu \u00fcst\u00fcn komplekslik bir yana, evrimciler a\u00e7\u0131s\u0131ndan b\u00f6ylesine ritmik bir d\u00fczen ile kapaklar\u0131n a\u00e7\u0131l\u0131p kapanmas\u0131 bile tek ba\u015f\u0131na b\u00fcy\u00fck bir sorundur. \u00c7\u00fcnk\u00fc hi\u00e7bir canl\u0131n\u0131n b\u00f6ylesine ritmik bir d\u00fczeni elde edinceye kadar bekleyecek zaman\u0131 yoktur.

Kapaklar\u0131n a\u00e7\u0131lma ve kapanma d\u00fczeninin, her canl\u0131da hen\u00fcz bir cenin halindeyken bile muntazam i\u015flemesi gerekmektedir. B\u00f6yle seri bir hareketin tesad\u00fcfen meydana gelen mutasyonlarla olu\u015fmas\u0131 ve bunun hi\u00e7bir aksama g\u00f6stermeden t\u00fcm canl\u0131larda tesad\u00fcfen kusursuz i\u015flemesi ise mant\u0131kl\u0131 hi\u00e7bir insan\u0131n kabul edemeyece\u011fi b\u00fcy\u00fck bir aldatmacad\u0131r.<\/p>\n
