The cardiovascular system is made up of the heart, arteries, veins and capillaries. It is responsible for moving vital blood, oxygen and nutrients throughout the body. The cardiovascular system is very important in the survival and maintaining homeostasis. The cardiovascular system functions to provide consistent movement of blood throughout the body so that it can provide nourishment to every cell and tissue in the body. Without constant circulation of blood, the tissues of the body will be deprived of nutrients and will sustain irreversible damage that may lead to death. For this reason, it is so important to maintain a healthy cardiovascular system, yet we still see an extraordinarily high incidence of cardiovascular pathology in the United States.
