The endocardium (pl.: endocardia) 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. [1]

Jul 26, 2024 · 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 the heart atria consists of …

Jun 9, 2024 · The endocardium is a thin, smooth tissue that makes up the lining of the chambers and valves of the heart. The innermost layer of the heart’s walls, it serves as a barrier between cardiac muscles and the bloodstream and contains necessary blood vessels.

Nov 3, 2023 · The endocardium is the innermost layer of the heart. It lines the inner surfaces of the heart chambers, including the heart valves. The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells.

Jan 20, 2025 · The endocardium is the innermost lining layer of the heart, which covers the internal surfaces of the heart chambers and valves. It is one of the three main layers of the heart wall, the other two being the myocardium (the muscular middle layer) and the …

Jan 4, 2024 · The innermost layer of the cardiac wall is known as the endocardium. It lines the cavities and valves of the heart. Structurally, the endocardium is comprised of loose connective tissue and simple squamous epithelial tissue – it is similar in its composition to the endothelium which lines the inside of blood vessels.

The developing endocardium demonstrates diverse plasticity given its potential to differentiate and transform into many cell types that contribute to the valves and myocardial chambers during embryogenesis.

The endocardium is a specialized form of endothelium that lines the inner side of the heart chambers and plays a crucial role in cardiac development. While comparatively less studied than other cardiac cell types, much progress has been made in ...

In this article, we review recent developments in the understanding of the embryonic origins of the endocardium. Specifically, we summarize vasculogenesis and specification of endothelial cells from mesodermal precursors, and we review the transcriptional pathways involved in …

The endocardium consists of a single layer of endothelial cells that create a smooth surface to facilitate efficient blood flow within the heart chambers. It helps prevent blood clotting by producing substances that inhibit platelet aggregation and regulate local vascular tone.
