FDA Statement: Original Opana ER Relisting Determination.

The heart is a vital organ located in the center of the chest with a slight tilt to the left. Using rhythmic muscle contractions, it circulates blood through veins and arteries, which supplies tissues with oxygenated blood and disposes waste.
The heart is located in a central tissue mass that divides the ribcage into two cavities between the two lungs. This central tissue consists of the heart, its associated blood vessels, the esophagus, and the trachea. The axis of the heart is tilted so that the apex (tip) of the heart points toward the lower left.
