Pericardial Fluid is Located in a Space External (Superficial) to the Visceral

Question

Pericardial fluid is located in a space external (superficial) to the visceral pericardium.

Accepted Answer

Pericardial fluid is located in the pericardial cavity, which is between the visceral layer of the serous pericardium (which closely adheres to the heart muscle) and the parietal layer of the serous pericardium (which lines the inner surface of the fibrous pericardium), thus making it external or superficial to the visceral pericardium.
