The outerside would be the Epicardium. The second layer would be the Myocardium. The last layer would be the Endocardium. There is also another layer which completely covers the heart. Its called the Percardium.

What is the Heart Sack?
The sac surrounding the heart is called the pericardium. The pericardium has two layers with fluid between them, and it serves to protect and anchor the heart.
Why do the two layers of the pericardium have to be cut in order to remove the heart from the pericardial sac?
Yes. He needs to cut through both the layers of pericardium.
Protective membrane that protects the heart?
The membrane that protects the heart is called the pericardium. It has two layers: - the visceral pericardium (the inner layer which touches the heart) - the parietal pericardium (the outer layer which touches other organs)
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 another name for the visceral layers of the pericardium?
The visceral pericardium is the outer sac that surrounds the heart. Another name for the visceral pericardium is the endocardium.
What are the layers of tissue that make up the pericardium?
Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
What is the layer of tissue or skin that encompasses the entire heart?
the heart muscle is enclosed by the 3 layers of tissue.the closest to the heart is the visceral layer of serous pericardium then parietal layer of serous pericardium and then the fibrous pericardium
Membrane that covers the heart?
The membrane surrounding the heart is called the pericardium. It is a fluid sac that serves several purposes. One of the purposes of the pericardium is it contains the heart in the chest cavity. The pericardium also prevents the heart from overexpanding when the blood volume in the heart increases.
What are the layers of the heart wall from superficial to deep?
The heart consists of three tissue layers: endocardium, myocardium, and pericardium. The endocardium, the innermost layer, lines the hearts chambers and is bathed in blood. The myocardium is the thick middle layer of the heart. Its cells are unique in that they physically resemble skeletal muscle but have electrical properties similar to smooth muscle. These cells also contain specialized structures that help to rapidly conduct electrical impulses from one muscle cell to another, enabling the heart to contract. The pericardium is a protective sac surrounding the heart, which consists of two parts: the inner serous pericardium and the outer fibrous pericardium. The serous pericardium has two layers--the visceral and the parietal. The visceral pericardium, also called the epicardium, is the inner layer, in contact with the heart muscle itself. The parietal pericardium is the outer, fibrous layer. In the pericardial cavity, between these two layers, is about 25 milliliters of pericardial fluid, a lubricant that reduces friction as the heart beats and changes position. The fibrous pericardium encases the serous pericardium. It is made of dense connective tissue and is attached to both the diaphragm and the base of the great vessels.
What is the transparent tissue that covers the heart called?
The pericardium. It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
What are the 4 walls of the human heart?
Actually, the heart is surrounded by a pericardium and its wall is made of 3 layers. Therefore, the terminology "4 walls of the human heart" is quite misleading. So, from outside to inside, we have: *Pericardium *Heart wall: -Epicardium -Myocardium -Endocardium
What is the fibrous sac of connective tissue that encloses the heart called?
The fibrous sac of tissue that encloses the heart is the pericardium. It provides protection for the heart.
