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.

  1. Endocardium is made up of specialized epithelium, called the endothelium. It covers the internal chambers of the heart, as well as the valves.
  2. Myocardium 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.
  3. Epicardium is the outermost layer, formed by epithelial tissue attached to the outer portion of the myocardium. It constitutes the visceral sheet of the pericardium.

The three layers of the heart have a specific purpose and are necessary for the normal functioning of this vital organ.
