The heart has three walls, or layers, of tissue. These layers work together to ensure proper heart function.
Here's a breakdown of each layer:
-
Epicardium: This is the outermost layer of the heart. It's a thin, protective layer.
-
Myocardium: This is the middle and thickest layer. It's made of cardiac muscle tissue responsible for the heart's contractions. This layer allows the heart to pump blood throughout the body.
-
Endocardium: This is the innermost layer, lining the heart chambers. It's a smooth layer that helps to prevent blood clots from forming inside the heart.
In summary, these three distinct layers - the epicardium, myocardium, and endocardium - form the wall of the heart.
