It's All In The Heart

While the circulatory system is busy providing oxygen and nourishment to every cell of the
body, let's
not forget that the heart, which works hardest of all, needs nourishment, too. Coronary
circulation
refers to the movement of blood through the tissues of the heart. The circulation of blood
through the
heart is just one part of the overall circulatory system.
Serious heart damage may occur if the heart tissue does not receive a normal supply of
food and
oxygen. The heart tissue receives nourishment through the capillaries located in the
heart.
