What is the white tissue covering the heart called?

The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. It provides lubrication for the heart, shields the heart from infection and malignancy, and contains the heart in the chest wall.

What is the epithelial lining of the heart?

Endocardium
Endocardium. The endocardium can be compared to the tunica intima of blood vessels. It forms the luminal surface of the heart and is composed of simple squamous epithelium. Deep to the endocardium is the subendocardial tissue, which contains loose vascularized connective tissue.

What is the white structure in the heart?

The parietal pericardium, in turn, forms the inner lining of the fibrous pericardium, thus the two membranes form a pseudo-tri layered structure. The fibrous pericardium is a tough, protective sac composed largely of white fibrous connective tissue.

What is the inner endothelial lining of the heart?

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.

Can pericarditis be fatal?

Two serious complications of pericarditis are cardiac tamponade and chronic constrictive pericarditis. These conditions can disrupt your heart’s normal rhythm and/or function. If left untreated, they may lead to death.

Why is the heart lined with squamous epithelium?

Simple Squamous Epithelia A single layer of thin, flattened epithelial cells lines the interior of blood vessels. They provide a slick surface that promotes a smooth flow of blood cells through the vessel.

Which of the following consists of epithelial tissue and inner lining of the heart?

The endocardium is composed of simple squamous epithelial cells which form the inner lining of the heart chambers. The endocardium connects to blood vessels that supply the heart muscle and contributes to the regulation of heart contractions.

What is the heart wall made of?

The heart wall consists of three layers: the endocardium, myocardium and epicardium.
