Explanation:

The pericardial cavity is the space between the visceral and parietal layers of the pericardium. The heart is enfolded (surrounded) by the pericardial sac (which includes the pericardial cavity around it), while "inside" is less anatomically accurate as the cavity is a potential space around the heart, not a container the heart is simply placed in. So the correct term is "enfolded by".

Answer:

enfolded by
