What is the Visceral Pericardium? Parietal pericardium: The outer layer of the pericardium which is a conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels.his small amount of fluid, the pericardial fluid, acts as a lubricant to allow normal heart movement within the chest. The word pericardium means around the heart. The inner part of the pericardium that closely envelops the heart is called the visceral pericardium or epicardium.

Pericardium The pericardium (from the Greek περί, around and κάρδιον, heart) is a double-walled sac containing the heart and the roots of the great vessels.The pericardial sac has two layers, a serous layer and a fibrous layer.It encloses the pericardial cavity which contains pericardial fluid. transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural cavity and the pericardial cavity are exaggerated since normally there is no space between the pleurae or between the pericardium and heart. Pericardium is also known as cardiac epidermis.

Equine Cardiovascular System - Horse Anatomy The pericardium is the membrane that surrounds and protects the heart. It is composed of two layers separated by a narrow cavity. The inner layer is firmly attached to the heart wall and is known as the visceral layer or epicardium. The outer layer is composed of relatively inelastic connective tissue and is termed the parietal layer. This fibrous layer prevents distension of the heart, thus preventing excessive stretching of the heart muscle fibres.

The Three Layers of the Heart Wall The fibrous pericardium encases, protects, and secures the heart. Inside the pericardium is the heart wall, and this is organized into three main layers. The outermost layer of the heart wall is the epicardium, which is also the innermost layer of the pericardium. The middle layer of the heart wall is the myocardium; this is the actual muscular layer of the heart responsible for contracting and pumping blood throughout your body.

Pericardium In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity, which contains a supply of lubricating serous fluid known as the pericardial fluid. When the visceral layer comes into contact with heart (not the great vessels) it is known as the epicardium.he pericardial sac has two layers, a serous layer and a fibrous layer. It encloses the pericardial cavity which contains pericardial fluid. The pericardium fixes the heart to the mediastinum, gives protection against infection, and provides the lubrication for the heart.

Pericardium - definition and function What is Pericardium, definition and function. Pericardium is a tough, two-layer membranous sac that encloses the HEART. The pericardium’s fibrous outer layer, called the fibrous pericardium, protects the heart from contact with the chest wall and other structures in the chest, including the LUNGS and the sternum.he inner layer of the pericardium is a filmy envelope. Its two surfaces are the parietal pericardium, which contacts the fibrous pericardium, and the epicardium, which covers the MYOCARDIUM somewhat like a wet tissue.

pericardium The serous membrane (covering membrane) which, in humans and other vertebrates, forms the wall of the pericardial cavity and holds the heart in place. The pericardium is made of two thin layers of tissue. Immediately surrounding the heart, and attached to it, is the visceral pericardium, or epicardium.The heart can slide easily on the visceral pericardium, thus allowing it to beat freely. The visceral pericardium has an external layer of flat mesothelial cells, which lies on a stroma of fibrocollagenous support tissue.ow, if you pretend that your fist is your heart, the two layers of the football bladder will be like the two layers of the pericardium which surround it. At the top, your wrist will represent the large blood vessels which carry blood to and from the heart.

Pericardium Parietal layer of serous pericardium: It lines the fibrous pericardium and is reflected around the roots of great blood vessels. At the region of reflection, it becomes continuous with the visceral layer of serous pericardium, which covers the heart closely.Visceral layer of serous pericardium: This layer is closely applied to the heart and is often called the epicardium.There exists a slit like space between the parietal and visceral layers of serous pericardium. This space is known as pericardial cavity and it contains a small amount of tissue fluid called pericardial fluid.ericardium is a fibroserous sac, which encloses the heart and roots of great vessels. It has two primary functions. Firstly, it restricts excessive movements of the heart so that injury to this vital organ of human body is avoided.

Pericardium In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity, which contains a supply of lubricating serous fluid known as the pericardial fluid. When the visceral layer comes into contact with heart (not the great vessels) it is known as the epicardium.he serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium. Both of these layers function in lubricating the heart to prevent friction during heart activity.

The Effects of Mixing Alcohol & Diet Pills Mixing alcohol and diet pills can cause undesirable side effects. Alcohol and diet pills both contain stimulants, but the stimulants found in each substance are different. Diet pills often contain stimulants known as uppers that increase heart rate, breathing and blood pressure. Alcohol contains stimulants known as downers that slow reflexes, thin the blood and make you drowsy.
