Normal Heart Tissues
The heart lays in a sac and is normally surrounded by a small amount of fluid within the sac. The heart normally has fat around the top (base) of it. The actual heart tissue is a dark red (liver color) and has a smooth surface. The inner surface should also be smooth. The left side of the heart is about 3 times the thickness of the right. The valves of the heart should be thin and connected to the wall of the heart by tendon like structures.
