Kan dola\u015f\u0131m\u0131, insan v\u00fccudunun hayati fonksiyonlar\u0131ndan biridir. Bu yaz\u0131da, kan\u0131n damarlar i\u00e7inde nas\u0131l hareket etti\u011fini ve bu hareketin ard\u0131nda yatan temel prensipleri inceleyece\u011fiz.<\/p>\n
Kan, kalbin pompalama g\u00fcc\u00fc sayesinde damarlar i\u00e7inde hareket eder. Kalp, kan\u0131 y\u00fcksek bir bas\u0131n\u00e7la arterlere (atardamarlara) pompalar. Bu bas\u0131nc\u0131n etkisiyle kan, arterlerden ince k\u0131lcal damarlara ve ard\u0131ndan daha b\u00fcy\u00fck damarlara (venlere) ge\u00e7er.<\/p>\n
