Answer:
The correct order in which the three layers of the heart meet, from the inside to the farthest from the blood is endocardium, myocardium and epicardium.
Explanation:
The three layers that make up the walls of the heart are called, from the innermost to the outermost endocardium, myocardium and pericardium.
- <em>Endocardium </em><em>is made up of specialized epithelium, called the endothelium. It covers the internal chambers of the heart, as well as the valves.
</em>
- <em>Myocardium</em><em> is the muscular layer that allows the contractile and pumping function of the heart. It is a type of muscle fiber similar to striated muscle, but called cardiac muscle fiber.
</em>
- <em>Epicardium </em><em>is the outermost layer, formed by epithelial tissue attached to the outer portion of the myocardium. It constitutes the visceral sheet of the pericardium.</em>
The three layers of the heart have a specific purpose and are necessary for the normal functioning of this vital organ.
