The epicardium is also referred to as which of the following?
Parietal pericardium.
Fibrous pericardium.
Serious pericardial layer.
Pericardial cavity.
Visceral pericardium.
Visceral pericardium.
The pericardial cavity is the potential space between which of the following?

What best describes the site where fluid accumulates with cardiac tamponade?
Pericardial cavity
Between epicardium and heart
Between fibrous pericardium and parietal pericardium
External to fibrous pericardium
Pericardial cavity
Cardiac tamponade, also known as pericardial tamponade, is when fluid in the pericardium (the sac around the heart) builds up and results in compression of the heart.
