pericardium - Correct Answer-parietal pericardium
Covering of the heart made of tough, white fibrous connective tissue -
Correct Answer-pericardium
Space between the parietal and visceral layers - Correct Answer-
pericardial cavity
Serous fluid secreted by the pericardial membranes that reduces
friction between the pericardial membranes as the heart moves inside
