MEMEL\u0130LER\u0130N V\u00dcCUT YAPISI
\n Memelileri ay\u0131rt etmek kolayd\u0131r. \u00c7\u00fcnk\u00fc memelilerin \u00e7o\u011funun v\u00fccudu k\u0131l, y\u00fcn ya da postla kapl\u0131d\u0131r. Post ya da k\u00fcrk leriden \u00e7\u0131k\u0131p b\u00fcy\u00fcr. Derinin alt\u0131nda bir kas ve ya\u011f tabakas\u0131 vard\u0131r. Kaslar iskelete ba\u011fl\u0131d\u0131r. Memelilerin iskeleti bir*\u00e7ok bak\u0131mdan s\u00fcr\u00fcngenlerle kurba\u011fagillerin iske*letine benzerse de,.karada ya\u015famaya daha uygun bi\u00e7imdedir. Memelilerin beyni korumaya yara*yan bir kafataslar\u0131, v\u00fccudu dik tutmaya ve sinir \u015feridini korumaya yarayan bir omurgalar\u0131, y\u00fc*re\u011fi ve akci\u011ferleri koruyan ve hayvan\u0131n solu*mas\u0131na yard\u0131m eden kaburga kemikleri ve d\u00f6rt “ayaklar\u0131” vard\u0131r. \u00c7o\u011fu memelilerde omurga bir kiri\u015f gibi v\u00fccudu ta\u015f\u0131r, d\u00f6rt ayak da destek i\u015fi g\u00f6r\u00fcr. Yaln\u0131z insanla maymun arka ayaklan \u00fczerinde dengede dururlar. Ancak iki ayak \u00fczerinde durmak d\u00f6rt ayak \u00fczerinde durmak kadar kolay de\u011fildir. \u00c7\u00fcnk\u00fc d\u00f6rt aya\u011fa da\u011f\u0131lan a\u011f\u0131rl\u0131k insan*da ve maymunda yaln\u0131z iki aya\u011fa da\u011f\u0131lm\u0131\u015ft\u0131r.
\n Memelinin v\u00fccudunu beyni ve sinir sistemi denetler. Sinirler beyinden \u00e7\u0131karak v\u00fccudun her yanma da\u011f\u0131l\u0131r. Ayr\u0131ca ikinci bir sinir sistemi daha vard\u0131r. Bu sistemin merkezi omuriliktir. Bu ikinci sinir sistemi, \u00f6rne\u011fin y\u00fcre\u011fin at\u0131\u015f\u0131 gibi hareketleri denetler. Hayvan uykuda ya da bilin\u00e7siz de olsa, sistem \u00e7al\u0131\u015fmas\u0131n\u0131 s\u00fcrd\u00fcr\u00fcr.<\/p>\n
Memeli besinini a\u011fz\u0131yla al\u0131r, midesinde sindirir. Besin mideden sonra ba\u011f\u0131rsaklara ge\u00e7er. Sindirim i\u015fi burada da devam eder. Sonra sindi*rilmi\u015f besin ba\u011f\u0131rsak duvarlar\u0131ndan kana kar\u0131\u015f\u0131r. Kan besini depolama organlar\u0131na \u2014karaci\u011fer gibi\u2014 ve v\u00fccudun geri kalan kesimlerine ta\u015f\u0131r.
\n Memeli solunmas\u0131 i\u00e7in gerekli havay\u0131 burun ****klerinden al\u0131r. Hava buradan akci\u011ferlere ge\u00e7er. Havadaki oksijen ci\u011ferlerde \u00e7\u00f6z\u00fclerek kana kar\u0131\u015f\u0131r. Besin kullan\u0131ld\u0131ktan sonra a\u00e7\u0131\u011fa \u00e7\u0131kan karbon dioksit de akci\u011ferlerde kandan ayr\u0131la*rak d\u0131\u015far\u0131 at\u0131l\u0131r. Balina, fok gibi deniz memelileri suya dalmadan \u00f6nce v\u00fccutlar\u0131ndaki karbon diok-sitten “temizlenebilirler”. Suyun alt\u0131ndayken ak*ci\u011ferlerinde daha \u00e7ok miktarda karbon dioksit toplan\u0131r. Hayvan su y\u00fcz\u00fcne \u00e7\u0131k\u0131nca bu karbon dioksiti d\u0131\u015far\u0131 p\u00fcsk\u00fcrt\u00fcr. P\u00fcsk\u00fcren bir balina az \u00f6nce bir dal\u0131\u015f yapm\u0131\u015f, suyun y\u00fcz\u00fcne yeni \u00e7\u0131km\u0131\u015ft\u0131r. Hayvan p\u00fcsk\u00fcrme s\u0131ras\u0131nda akci\u011ferlerin-deki \u0131l\u0131k, \u0130slak, karbon dioksitli havay\u0131 d\u0131\u015far\u0131 atar.
\n Besinle oksijen, kanla v\u00fccudun her yanma da\u011f\u0131l\u0131r. Y\u00fcrek kan\u0131 atardamarlara pompalar. Kullan\u0131lan kan toplardamarlar arac\u0131l\u0131\u011f\u0131yla y\u00fcre\u011fe d\u00f6ner. Toplardamarlar\u0131n i\u00e7indeki kan yaln\u0131z y\u00fc*re\u011fe do\u011fru akabilir. \u00c7\u00fcnk\u00fc damarlar\u0131n i\u00e7inde kan\u0131n gerisin geri d\u00f6nmesini \u00f6nleyen kapak\u00e7\u0131klar vard\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
