pericardium

pericardium A conical bag which holds the heart. There is an outer fibrous covering, and within this a more delicate membrane: a closed sac, into which the heart is invaginated from behind, so that the two layers of membrane are in contact with each other. There is thus a potential space between the layers, which may be expanded with fluid in the condition of pericarditis, or with blood in penetrating injuries; since there is no exit, accumulated fluid interferes with the pump action, and needs to be aspirated.
