Study Notes
Layers of the Heart
- The myocardium is responsible for the pumping action of the heart, making it a crucial layer.
Composition of the Endocardium
- The endocardium, the inner layer of the heart, is composed of epithelial tissue.
Composition of the Myocardium
- The myocardium, the middle layer of the heart, is composed of muscle fibers.
Space between the Visceral and Parietal Layers
- The space between the visceral and parietal layers of the pericardium is filled with pericardial fluid, which reduces friction between the layers.
Function of the Pericardium
- The pericardium, a sac-like structure surrounding the heart, protects the heart, reduces friction, and anchors the heart to surrounding structures.
