If we increased the enzymes, our food would break down too fast to process it. If there were no enzymes, the food wouldn't break down. Enzymes are so important, that without them in our saliva, we wouldn't be able to swallow or chew our food.

Answer:
The parietal layer of the serous pericardium is also known as the epicardium of the heart wall.
Explanation:
The pericardium is a sac composed of two layers which surround the pericardial cavity. The two layers of the pericardium are the fibrous and serous pericardium and the serous pericardium is further divided into two layers: the visceral and the parietal layers.
The fibrous pericardium is composed of the thick connective tissue and thus prevents overfilling of the ventricles.
The parietal pericardium lines the internal surface whereas the "visceral pericardium layer" is the innermost layer and is known as the epicardium of the heart wall.
Thus, the selected option is correct.
