pericardial sac - (pronounced) (PAYR-ih-KAR-dee-um) The thin, fluid-filled sac that surrounds the heart, including the apex, which connects to large blood vessels such as the aorta and vena cava. The pericardium is an outer layer of connective tissue that holds the heart in place in the chest, protects it from inflammation, and acts as a barrier against infection. It also keeps the heart from expanding and filling with too much blood. The pericardium is also made up of two thin, inner layers of tissue with a small amount of fluid between them. The fluid keeps the tissues from rubbing against each other as the heart moves in the pericardium
