  1. pericardiumnoun

    A serous membrane that surrounds the heart allowing it to contract.

Samuel Johnson's Dictionary

  1. Pericardiumnoun

    The pericardium is a thin membrane of a conick figure that resembles a purse, and contains the heart in its cavity: its basis is pierced in five places, for the passage of the vessels which enter and come out of the heart: the use of the pericardium is to contain a small quantity of clear water, which is separated by small glands in it, that the surface of the heart may not grow dry by its continual motion. John Quincy

    Etymology: πεϱὶ and ϰαϱδία; pericarde, Fr.


  1. Pericardium

    The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium). It encloses the pericardial cavity, which contains pericardial fluid, and defines the middle mediastinum. It separates the heart from interference of other structures, protects it against infection and blunt trauma, and lubricates the heart's movements. The English name originates from the Ancient Greek prefix "peri-" (περί; "around") and the suffix "-cardion" (κάρδιον; "heart").


  1. pericardium

    The pericardium is a thin, double-layered sac that surrounds the heart and the roots of the major blood vessels connected to it. Its purpose is to protect the heart, anchor it in place within the chest, and prevent it from overfilling with blood. The fluid between the two layers of the pericardium reduces friction as the heart beats.

Webster Dictionary
