What is the muscular, middle layer of the heart?

Explanation:
The heart wall has three layers, and the muscular middle layer is the myocardium. This layer is made of cardiac muscle and is responsible for the heart’s pumping action, contracting to push blood out to the body and lungs. The inner lining, the endocardium, covers the chambers and valves and is smooth to reduce friction. The outer layer, the epicardium, forms part of the heart wall itself, while the pericardium is a surrounding sac that protects the heart and provides lubrication. So, the muscular middle layer that actually contracts to pump blood is the myocardium.
