Question 2 of 13

1

Functions of pericardium

Select one or more of the following:

Facilitation of secure intrathoracic cardiac stability
Friction reduction between heart & the mediastinum structures
Nutrition of the heart
Limitation of cardiac distention and chamber dilation
Uniform cardiac distribution of pericardial cavity hydrostatic pressure
Formation of a barrier to stop infection
Facilitation of atrial filling by promoting negative pericardial pressure during ventricular systole
(pericardium + pleural fluid): formation of a system that automatically applies compensating hydrostatic pressures to the cardiac periphery when accelerating forces act
