What Is the Pericardium?

The pericardium is a saclike structure located just under the skin on either side of your heart. It contains blood vessels (the main one being the pulmonary artery) and nerves that are vital to life. The pericardium is made up of two layers: the outer layer, which is mostly connective tissue; and the inner layer, which consists of muscle fibers.

Pericardium, also known as the pericard, is a sac-like structure that encloses the heart. It has unique blood vessels, nerve supply, and lymphatics.


The pericardium plays a number of important roles in the body, including:

It provides a physical barrier between the central nervous system (Nervous system, or the brain and spinal cord) and the exterior of the body.

It acts as a reservoir for blood.
