The heart is contained within the pericardial sac. Image above shows the pericardial sac in situ.
Image above shows removal of the pericardial sac revealing the heart.
This young girl with connective tissue disease shows "water bag" sign, which indicates presence of pleural effusion. This sign is due to gravitational accumulation of the pericardial fluid towards the dependent base of the heart, hence appearing as if a bag filled with water is being laid on a flat surface.
