Nov 3, 2023 · The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. Branches of the heart’s conduction system are immersed into the subendocardial layer.

- Epicardium. Epicardium (epi-cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.
- Myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.
- Endocardium. 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.

- Summary
The heart, tasked with pumping blood throughout the body, is composed of four chambers, and these are lined with endocardium. As the innermost layer of the heart’s walls, it serves two important functions: 1. Anatomic function: A tissue covering the inside of the heart, the endocardium keeps the blood flowing through the heart separate from the myo...
Alongside what it does, it’s also important to get a sense of the location and structure of the endocardium.
The endocardium, an inner lining of the heart, contains blood vessels and transmits electrical impulses that keep the heart beating properly. It is found on the inside walls of all four chambers of the heart. Inflammation, infection, and tissue changes in the endocardium can lead to significant and often life-threatening health conditions. Talk to ...
Mar 2, 2024 · Right Atrium. 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 epicardium (the outer layer). Location The endocardium is located inside.
Aug 4, 2023 · The epicardium is the outermost layer of the heart wall made up of mesothelium, fats, and connective tissues. It forms the inner serous layer of the pericardium; hence, it is also known as the visceral serous pericardium. Epicardium encloses the heart as well as the root of major blood vessels emerging from the heart like the aorta and the two ...
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.

What are the layers of the heart wall?
The inner layer of the heart wall is the endocardium, composed of endothelial cells that provide a smooth, elastic, non-adherent surface for blood collection and pumping. The endocardium may regulate metabolic waste removal from heart tissues and act as a barrier between the blood and the heart muscle, thus controlling the composition of the extracellular fluid in which the cardiomyocytes bathe.
