Endocardium the thin inner lining of the heart chambers that also forms the surface of the valves. The heart cavity is divided down the middle into a right and a left heart which in turn are subdivided into two chambers. A thin layer of tissue the pericardium covers the outside and another layer the endocardium lines the inside.
In most people the heart is located on the left side of the chest beneath the breastbone.
