Pericardial cavity is lubricated and reduces friction as the heart constantly rubs against its surroundings. It also adds a small amount of mechanical protection against direct physical injury to the heart. However the pericardial cavity is better known for its capacity to accumulate fluid (blood, interstitial fluid, pus) in diseased conditions (perforation, inflammation - pericarditis, infection) and press on the heart, reducing its pumping capacity in a condition called cardiac tamponade.
