The circulatory system is one of the main systems in the human body. It is a large web of organs and vessels. The human body relies on this system to deliver nutrients, oxygen and other gases through the blood. This system is made up of three separate structures that work together: the heart, lungs, arteries, veins, coronary and portal vessels. The heart, which is the main organ in the circulatory system, beats about 3 billion times in an averages person's life. About 2,000 gallons of blood travel through the body daily. Without this system, the body would not be able to fight diseases, or maintain a normal body temperature.Thursday, June 5, 2014
