Canadian Cardiac Vascular Nursing - Test Reviews Sample Questions

The internal layer of the heart is covered with which of the following?
 

Correct Answer:
endocardium


the correct answer to the question regarding which layer covers the internal surface of the heart is the endocardium. the endocardium is a thin layer of endothelial tissue that lines the interior of the heart chambers and valves. it plays a crucial role in maintaining the function of the heart by providing a smooth lining for the chambers of the heart, which minimizes surface resistance to the blood flowing through the heart.

it is important to distinguish the endocardium from other layers of the heart. above the endocardium is the myocardium, which is the thick, muscular middle layer responsible for the pumping action of the heart. the outermost layer of the heart wall is the epicardium, which is a thin layer of connective tissue that also covers the coronary arteries and veins that are situated on the surface of the heart.

the pericardium is another important structure, but it is not a layer of the heart wall itself; rather, it is a double-walled sac that encloses the heart. the pericardium consists of two parts: the fibrous pericardium (the outer layer) and the serous pericardium (the inner layer). the serous pericardium is further divided into two layers: the parietal layer, which lines the inner surface of the fibrous pericardium, and the visceral layer, which is the same as the epicardium.

therefore, when asked about the internal layer covering the heart, the endocardium is the accurate response. the epicardium and the pericardium, although important, are associated with the external aspects of the heart's structure, either as the outermost layer of the heart wall or as a protective sac surrounding the heart.
