What organ of the body has a pericardium, pulmonary trunk, and superior vena cava?
Pericardium which is fused to and inseparable from the fibrous pericardium, and the "visceral pericardium", which is part of, or in some textbooks synonymous with, the epicardium. Both of these layers function in lubricating the heart to prevent friction during heart activity. The visceral layer extends to the beginning of the great vessels (the large blood vessels serving the heart) becoming one with the parietal layer of the serous pericardium. This happens at two areas: where the aorta and pulmonary trunk leave the heart and where the superior vena cava, inferior vena cava and pulmonary veins enter the heart. In between
Fold of left vena cava the vein of the left atrium (oblique vein of Marshall), which opens into the coronary sinus. Fold of left vena cava The fold of the left vena cava, ligament of the left vena cava, or vestigial fold of Marshall, is a triangular fold of the serous pericardium that lies between the left pulmonary artery and subjacent pulmonary vein. It is formed by the folding of the serous layer over the remnant of the lower part of the left superior vena cava (duct of Cuvier), which becomes obliterated during fetal life, and remains as a fibrous band stretching from the highest
