where does the pericardium attached to the heart
Pericardium The pericardium fixes the heart to the mediastinum, gives protection against infection, and provides the lubrication for the heart. It receives its name from Ancient Greek peri (περί; "around") and cardion (κάρδιον; "heart").
Heart The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.[1] Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes.[2] In humans, the heart is located between the lungs, in the middle compartment of the chest.[3]
