The human body has a unique structure. The cornerstones of this unique structure are Movement, digestive, respiratory, excretory and circulatory systems. The circulatory system, also called the cardiovascular system, distributes the nutrients and oxygen required for the body systems to work in a coordinated way among the systems.

About a quarter of a million people have heart attacks every year in our country, and this number will continue to increase in the future.
