Document Summary

* the heart sits within a sac formed by pericardium (pericardial sac) * pericardium is a fibrsouserous membrane that covers the heart and the great vessel roots. * serous pericardium: a single layer of serous membrane that lines the internal surface of the fibrous pericardium and at the root of the great vessels it reflects away from the root and lines the surface of the heart. *the serous pericardium that covers the surface of the heart is the visceral layer of serous pericardium. The serous pericardium that covers the fibrous pericardium is the parietal layer of serous pericardium. A potential space between the parietal and visceral layers of serous pericardium. Contains a small amount of fluid, (it lubricates the surface between the two layers of serous pericardium pleural & visceral) providing a frictionless environment. * during development our heart rotates towards the left leads to right chambers lying at the front and left chambers lying mostly at the back.
