Yes, it is.
The pericardial sac is lined with a double-layered membrane called the serous pericardium. The inner layer is the visceral pericardium (or epicardium) which is in contact with the heart, and the outer layer is the parietal pericardium which is attached to the surrounding structures.
Peri 'cardial or Pericardium, is the membranous sac enclosing the heart.
serous pericardium
The pericardial sac contains the heart and pericardial fluid which serves to protect the heart. The fluid is secreted by the serous visceral pericardium and is similar to the cerebral spinal fluid that cushions the brain.
The pericardial sac is filled with pericardial fluid, a clear fluid that acts as a lubricant between the layers of the pericardium to allow the heart to move smoothly during contractions.
The space between the epicardium and the parietal pericardium is called the pericardial cavity. This cavity contains a small amount of pericardial fluid that acts as a lubricant to reduce friction between the membranes during heart contractions.
The visceral pericardium, also known as the epicardium, is the innermost layer of the pericardium that directly covers the heart. On top of the visceral pericardium lies the parietal pericardium, which is the outer layer of the pericardial sac. Between these two layers is the pericardial cavity, which contains pericardial fluid that reduces friction during heart movement. Additionally, surrounding the parietal pericardium, there may be fat and connective tissue that provide cushioning and support.
The pericardial sac (or pericardium) is a dual-walled sac that contains the heart and the roots of the great vessels (vena cavae, pulmonary arteries, pulmonary veins, aorta, brachiocephalic arteries and veins, carotid artery and subclavian artery).
Pericardial means pertaining to the pericardium, the sac around the heart.
The pericardial sac contains the pericardial fluid, which serves to lubricate the heart and reduce friction during its contractions. This double-walled structure encases the heart, providing protection and stability while allowing for the necessary movement of the heart as it beats. The outer layer, called the fibrous pericardium, is tough and helps anchor the heart in place, while the inner layer, or serous pericardium, produces the fluid that fills the sac.
Yes. He needs to cut through both the layers of pericardium.
