The Heart Wall Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels. The endocardium of heart atria consists of smooth muscle, as well as elastic fibers.

- The Pericardium. The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. It shields the heart from infection or malignancy and contains the heart in the chest wall.It also prevents the heart from over-expanding when blood volume increases, which keeps the heart functioning efficiently.he Pericardium.

Infective Endocarditis Infective endocarditis is infection of the endocardium, usually with bacteria (commonly, streptococci or staphylococci) or fungi. It causes fever, heart murmurs, petechiae, anemia, embolic phenomena, and endocardial vegetations.

Endocarditis Endocarditis (EN-do-kar-DI-tis) is an infection of the inner lining of your heart chambers and valves. This lining is called the endocardium. The condition also is called infective endocarditis (IE). The term endocarditis also is used to describe an inflammation of the endocardium due to other conditions. This article only discusses endocarditis related to infection. IE occurs if bacteria, fungi, or other germs invade your bloodstream and attach to abnormal areas of your heart.

- The word endocarditis comes from the word endocardium. The endocardium is the innermost tunic of the heart, including the endothelium and subendothelial connective tissue; in the atrial wall, smooth muscle and numerous elastic fibers also occur.

- The myocardium, or cardiac muscle, is the thickest section of the heart wall and contains cardiomyocytes, which are the contractile cells of the heart. As type of muscle tissue, the myocardium is unique and distinct compared to all other muscle tissues in the human body.

The Heart The atria and the ventricles are separated by valves, which allow the blood to flow through the heart in one direction and prevent back flow of blood. The wall of the heart is made up of three layers. The outer layer is called the epicardium. The middle layer is the actual heart muscle and is called the myocardium. The inner layer of the heart is called the endocardium. The heart is contained within a sac called the pericardium. The sole purpose of the heart is to pump blood to and from the rest of the body. The right side of the heart pumps blood without oxygen to the lungs where oxygen is picked up by the red blood cells.

- Pericardium: The conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels. The pericardium's outer coat (the parietal pericardium) is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone.

- Heart valves are made up of connective tissue that is collectively called the endocardium. Depending on the specific valve it can also be referred to as a cusp/s(aorta & pulmo … nary) or leaflet/s(mitral & tricuspid).

Histology Testbank: Cardiovascular System 1a The heart wall consists of three layers: the endocardium, myocardium and epicardium. The endocardium is the thin membrane that lines the interior of the heart. The myocardium is the middle layer of the heart. It is the heart muscle and is the thickest layer of the heart.

Endocarditis: What you need to know Endocarditis is inflammation of the heart lining, heart muscles and heart valves. Endocarditis is a rare condition. Endocarditis is also known as infective endocarditis, bacterial endocarditis, infectious endocarditis, and fungal endocarditis.

Heart The myocardium is the muscular middle layer of the heart wall that contains the cardiac muscle tissue. Myocardium makes up the majority of the thickness and mass of the heart wall and is the part of the heart responsible for pumping blood. Below the myocardium is the thin endocardium layer.

The intervening space between these layers is filled with pericardial fluid.

Endocarditis URL of this page: //medlineplus.gov/ency/article/001098.htm. Endocarditis is inflammation of the inside lining of the heart chambers and heart valves (endocardium). It is caused by a bacterial or, rarely a fungal infection. Endocarditis can involve the heart muscle, heart valves, or lining of the heart. Some people who develop endocarditis have a: Birth defect of the heart.

Overview Endocarditis is an infection of the inner lining of your heart (endocardium). Endocarditis generally occurs when bacteria or other germs from another part of your body, such as your mouth, spread through your bloodstream and attach to damaged areas in your heart. Left untreated, endocarditis can damage or destroy your heart valves and can lead to life-threatening complications.

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. 1 Function.

Endocardium Illustration depicting the layers of the heart wall including the innermost endocardium. The 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. The endocardium also provides protection to the valves and heart chambers.
