Introduction:
The circulatory system is one of the most important systems in the human body. It is also called as the cardiovascular system; it nourishes organs with oxygen along with other important minerals and at the same time takes away carbon di-oxide and other waste products from the blood. The circulatory system flows with blood through vessels; there are three different vessels, namely the arteries, veins, and capillaries. The arteries carry oxygenated blood to organs, and veins carry de-oxygenated blood from organs, while the capillaries act as a connection in between veins and arteries.
