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.he heart contains four chambers. The two upper chambers are the atria and the two lower chambers are the ventricles. On the cranial surface of each atrium is a pouch-like appendage called an auricle which is thought to increase the capacity of the atrium slightly.

Cardiomyopathy- Weakened Heart Muscle Your heart is divided into four sections called chambers. The chambers are separated by the septum, a thick wall. The two top chambers are called atria, and they receive blood coming into the heart. The two bottom chambers are called ventricles, and they send blood out from the heart. Your heart contains a left and right pumping system. The left-sided pumping system consists of the left atrium and the left ventricle.

- The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes.The heart is located in the middle compartment of the mediastinum in the chest.n a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.

List the membranes that cover the heart.? The epicardium is the layer immediately outside of the heart muscle proper (the myocardium). In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity. It is normally lubricated by a film of pericardial fluid. Too much fluid in the cavity (such as in a pericardial effusion) can result in pericardial tamponade (compression of the heart within the pericardial sac).

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.

Boundless Biology The outer layer of cells is called the epicardium, the second layer of which is a membranous layered structure (the pericardium) that surrounds and protects the heart; it allows enough room for vigorous pumping, but also keeps the heart in place, reducing friction between the heart and other structures.

What is the Myocardium? 10 most extreme places on Earth. The myocardium is the muscle layer of the heart, responsible for the heart's pumping action, which supplies the entire body with blood. The myocardium consists of cardiac muscle, a type of muscle unlike any other muscle in the body.

Heart The middle layer of the heart wall is the myocardium, which is the cardiac muscle – a layer of involuntary striated muscle tissue surrounded by a framework of collagen. The myocardium is also supplied with blood vessels, and nerve fibers by way of the epicardium that help to regulate the heart rate.

Human Heart: Anatomy, Function & Facts The heart's outer wall consists of three layers. The outermost wall layer, or epicardium, is the inner wall of the pericardium. The middle layer, or myocardium, contains the muscle that contracts. The inner layer, or endocardium, is the lining that contacts the blood.

Endocardium The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart. The outer layer of the heart is termed epicardium and the heart is surrounded by a small amount of fluid enclosed by a fibrous sac called the pericardium.he endocardium is the innermost layer of tissue that lines the chambers of the heart. Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels.

Library of Notes The pericardium is the double walled sac that contains the heart and the roots of the great vessels that leave from or enter the heart. There are two layers of the pericardial sac: Fibrous Pericardium: The fibrous pericardium is a strong layer which covers the heart. It is made up mostly of connective tissue. Its job is to protect the heart from overstretching and also anchor it in place. This layer is the most superficial layer of the pericardium.

What is the membranes that surround the heart called? The pericardium is in the thoracic cavity and partially surrounds the heart. The heart is also supported by parietal and visceral pericardium. These all are serous membranes. Serous membranes secrete a watery fluid that lubricates and helps minimize friction between organs and membranes.

What is pericarditis? Pericarditis (PER-i-kar-DI-tis) is a condition in which the membrane, or sac, around your heart is inflamed. This sac is called the pericardium (per-i-KAR-de-um). The pericardium holds the heart in place and helps it work properly. The sac is made of two thin layers of tissue that enclose your heart. Between the two layers is a small amount of fluid.

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.
