The Human Heart

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest.

The buildup of plaque occurs over many years. (nhlbi.nih.gov) CHD AND TREATMENTS: CHD is the most common type of heart disease. In the United States, CHD is the #1 cause of...
