ANATOMY

Detailed explanation-1: -Endocardium: The endocardium is a thin, smooth squamous endothelium layer that lines the inside of the heart. The endocardium is the inner most layer of the heart wall and is responsible for keeping blood clots from sticking to the inside of the heart in order to avoid potentially deadly blood clots.

Detailed explanation-2: -The endocardium is the innermost layer of the heart and lines the chambers and extends over projecting structures such as the valves, chordae tendineae, and papillary muscles.

Detailed explanation-3: -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.

Detailed explanation-4: -The heart is protected by the PERICARDIUM which is the protective membrane surrounding it. The heart has FOUR CHAMBERS, in the lower heart the right and left Ventricles, and in the upper heart the right and left Atria.

Detailed explanation-5: -The endocardium is composed of the endothelium and the subendothelial connective tissue layer. The subendocardium is found between the endocardium and myocardium and contains the impulse-conducting system.
