   Aug 31, 2023 · The leaflets and cusps that make up the heart valves are made up of layers of connective tissue that are histologically divided into three layers. The semilunar valves are divided into: Ventricularis - which is in direct contact with pulsatile blood and directed toward the ventricles.

   • The Heart Wall Is Composed of Three Layers. The muscular wall of the heart has three layers. The outermost layer is the epicardium (or visceral pericardium).
   • The Atria Are the Heart’s Entryways for Blood. The left atrium and right atrium are the two upper chambers of the heart. The left atrium receives oxygenated blood from the lungs.
   • Each Heart Beat Is a Squeeze of Two Chambers Called Ventricles. The ventricles are the two lower chambers of the heart. Blood empties into each ventricle from the atrium above, and then shoots out to where it needs to go.
   • The Valves Are Like Doors to the Chambers of the Heart. Four valves regulate and support the flow of blood through and out of the heart. The blood can only flow one way—like a car that must always be kept in drive.

   Layers. The wall of the heart is composed of three layers of unequal thickness. From superficial to deep, these are the epicardium, the myocardium and the endocardium (see Figure 6.1.4). The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier.
