Yes. He needs to cut through both the layers of pericardium.

What does the percardium do?
The pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.
The membrane that lies the heart and also forms the valve flaps is the?
This membrane is known as the endocardium. From the inside out, the heart's layers go as so : endocardium, myocardium, epicardium (visceral pericardium), pericardial cavity, and parietal pericarium.
Surface of the heart?
The pericardial fluid acts as a lubricant and reduces friction between the opposing surfaces as the heart beats (contacts). The pericardial fluid is secreted by the pericardial membranes.
Is visceral pericardium deep to the parietal pericardium?
Yes, the visceral pericardium adheres to the outside surface of the myocardium (heart muscle), while the parietal pericardium lies outside of the visceral pericardium. There is a small amount of lubricating fluid between these two membranes in the potential space known as the pericardial space. If an abnormal amount of fluid of any kind builds up in this space, it is called a pericardial effusion.
What is the pericardial space and where is it located?
The pericardial space is located in between the parietal and visceral pericardium, contains 10-20 ml of fluid to cushion and protect the heart.
What is the heart covered with?
fibrous pericardium (tough, dense Connective tissue), parietal pericardium (pericardial cavity) , visceral pericardium (pericardial cavity)
What is the Functions of pericardial fluid?
Surrounding the heart is a fibrous sac called the pericardium. This sac protects the heart, and is actually composed of two layers: an inner visceral one and an outer parietal one. When the heart moves (i.e. when the heart beats), these two layers move with it. For this to happen, it is important that there is no friction between the two layers of the pericardium, which is why pericardial fluid lines the inner space between the them. Much like oil in an engine, the pericardial fluid makes for less friction between the inner and outer layer of the pericardium.
How does the pericardium work?
pericardium consists of two layers 1 fibrous layer which prevents overstretching of heart and anchors it in the mediastinum. 2 serous pericardial which again consists of two layers a- parietal pericardial that covers the heart and fuses the organ with fibrous layer b- visceral layer that lines the wall of heart and adheres tightly to the heart surface. in b/w parietal and visceral there's a fluid cavity known as pericardial cavity, filled with pericardial fluid that resists friction b/w two layers.
What is the space between the parietal and visceral layers of the pericardium normally filled with?
The space between the parietal and visceral layers of the pericardium is called the pericardial cavity and it is filled with a thin layer of fluid called pericardial fluid. The pericardial fluid lubricates the two membranes, allowing them to glide over each other without any friction when the heart beats.
What is the fluid sac that surrounds the heart?
Yes, it is.
What is water in the pericardium?
this is not water this a fluid called pericardial fluid which prevent friction between heart and pericardium.
Is water in the pericardium?
this is not water this a fluid called pericardial fluid which prevent friction between heart and pericardium.
What is pericardial?
Peri 'cardial or Pericardium, is the membranous sac enclosing the heart.
What does the pericardial membrane cover?
visceral pericardium,myocardium,endocardium
What does the percardium do?
The pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.
The outer covering of the heart?
The heart is encased in two protective layers. The outer layer -- the pericardium -- covers the heart. It folds in on itself at the aorta forming the epicardium of the heart. Between these layers is a small amount of fluid (10-50 ml) that affords the layers a non-stick surface.
What is the function of the pericardium in the rat?
A double membranous sac which envelops and protects the heart. The layer in contact with the heart is referred to as the visceral layer, the outer layer in contact with surrounding organs is the parietal pericardium. In between the two layers is the pericardial space. A double-layered serous membrane that surrounds the heart.
