Cardiovascular system

Your body's transportation system

Main purpose

To transport oxygen and nutrients to all tissues so diffusion can take place and every cell gets it necessary materials to function and reproduce

How it works

The circulatory system or cardiovascular system is a long system of veins, arteries, arterioles, venules, and capillaries including the heart surrounded by the pericardium all contribute to getting nutrients and oxygen to every cell in the body. Red blood cells carry oxygen and the arteries are used as a highway for nutrients and white blood cells. Almost everything uses the cardiovascular system as a transportation system. As the blood loses oxygen it goes from high pressure to lower pressure until its pumped back into the heart and is given more oxygen. Without the circulatory system in optimal health, our entire body is at risk.
